Arab Post Day update and more to come

Both previous blog pages triggered attention from collectors and resulted in additional information that help complete the catalogue:

Regarding the Arab Postal Day issue [T20250803], two additional countries have to be added to the already reported list (Algeria, Iraq, Tunisia, and the United Arab Emirates) namely, Egypt and Oman which issued their stamps respectively on August 3, 2025 and August 10, 2025 (Information provided by Mohamed Achour Ali Ahmed, Algeria and Ali Allawati, Oman).

The 80th Arab League anniversary issue from March 22, 2025 [T20250322] was also completed by two stamps issued in miniature sheets of 3 pairs from the United Arab Emirates. These stamps were issued on August 18, 2025 (Information provided by Kenneth Sequeira, Singapore).

The previous blog page was also missing the image of the Russian stamp jointly issued with North Korea on August 15, 2025. Illustration was provided by Kenneth Sequeira, Singapore, confirming the twin character.

I also made a comment earlier that embroided stamps are never used postally. Henri Aronis (France) provided a proof that this can happen with a Swiss stamp (year 2000), although not part of a joint issue. As expected, the thickness of the ‘stamp’ makes cancellation illegible. This cover was sent from Switzerland to Niger. Thanks Henri.

Jaap Sarelse (the Netherlands) reacted on the comments provided earlier about the July 5, 2025 Cape Verde – Portugal joint issue and at the same time provided information about Angola, a third country joining this issue, with the following:

The text suggests that it is a joint issue in which only Cape Verde and Portugal are involved. However, Angola is also involved with an identical stamp. Not to commemorate Angolan independence, but purely focused on the independence of Cape Verde. Some evidence:

  • In the leaflet of the Portuguese Post (6 pages) the text on page 5, 7th and 8th line from the bottom reads: ‘To help consolidate the historic memory of the founding of the Republic of Cabo Verde, a joint stamp issue is being released by Angola, Cabo Verde and Portugal’.
  • On page 5, one can find the stamps of Angola on the top row. Cabo Verde is also mentioned on this stamp at the bottom right.
  • Finally, only Cabo Verde is mentioned in the logo on page 1. I suspect that in the context of ’50 anos Independência Nacional’ Angola will get its own joint issue and that the name Angola will then adorn below the stars in the logo

Thanks, Jaap for this complement. Catalogue will be updated. Here are the additional illustrations (Angola stamp illustrations provided by Kenneth Sequeira):

Additional information relative to issues to come include the following:

  • The Oman – Russia originally scheduled for April 22, 2025, is now postponed to September 26, 2025 (Oman source) or October 15, 2025 (Russian source), not clear at this stage. It will show maps and honour Omani explorer Ahmed bin Majid and the Russian traveler Afanasy Nikitin
  • Kenneth Sequeira reported also two modifications in the Russian philatelic programme for 2025: a) the RCC stamps will be issued on August 23, 2025, but over the past years these stamps involving all CIS countries were not anymore considered as joint and there is no hint that this will change this year; b) the anniversary of the liberation of Korea will be celebrated by overprinting the August 15, 2025 joint issue with North Korea. These stamps will be issued on September 2, 2025
  • On October 7, 2025, the France – Japan is also confirmed. Japan stamp designs became available (information provided by Dominique Josse, France)

  • On August 15, 2025, Argentina issued a stamp to celebrate 60 years of immigration from Korea. No stamps related to the same topic was seen so far in the South Korea philatelic program. This issue may remain unilateral (information provided by Enzo Cafaro, Italy)

  • Our friend Luis Alejandro Malanco Reyes (Mexico) is working on a Mexican stamp catalogue (which of course includes also joint issues involving Mexico) and brought on line the first part of his work (years 2001-2025) with free access: Catálogo Filatélico México . Congratulations Luis and keep doing the good job.

Finally, some information about the next joint crypto-stamps issue (not recommanded to include in the joint issue collection as explained earlier): This will be the fourth crypto joint issue after the 2022 Austria-Netherlands (Ox), 2023 Austria-Luxembourg-Netherlands (Lion) and 2024 Austria-Belgium-Luxembourg-Netherlands (dragon) issues. The theme for this fourth issue is the Greek world of the gods. Five countries will participate and they made the following choice: Portugal – Poseidon, Austria – Zeus and Hera (2 stamps), Belgium – Athena, Luxembourg – Artemis and the Netherlands – Hermes.

Jaap Sarelse has succesfully created joint stamp covers with the previous crypto stamps and will try again this year with the six stamps. He provided the picture of the copy from year 2024. Such documents are close to unique.

The catalogue was update with all above new data. See updated Vol 1, Vol 15 and Vol 16

Arab Postal Day 2025

On August 3, 2025, Arab countries join to celebrate the Arab Postal Day with a stamp showing an identical design ‘Towards more innovative postal services’. So far, this issue involves Algeria (August 3), Iraq (August 3), Tunisia (August 3), and United Arab Emirates (August 3). More countries will probably be added (Information provided by Mohamed Achour Ali Ahmed, Algeria and Kenneth Sequeira, Singapore).

Additionally to earlier information related to the 80th anniversary of Arab League [T20250322], Kenneth Sequeira (Singapore) informed us that Sudan issued three stamps with three different denominations, not a single one as previously announced.

In the meantime, Qatar became also another country to be added to this series. The stamp was issued on June 15, 2025. There are still some chances that additional Arab countries will have to be added to this series.

Unilateral issues update

The previous page on Unilateral Issues triggered a lot of answers leading to some new joint issues to be confirmed for the end of the year 2024.

Let us first start with the Kazakhstan – Morocco issue. A Kazakhstan stamp, in miniature sheets of 8 units, was released as early as September 30, 2024 with a topic related to the 30th anniversary of relationship depicting local Gastronomy (camel milk, kumis, dates), but above all with a stamp bearing the words “Joint issue Kazakhstan – Morocco”. Eventually, the Moroccan stamp was released on December 25, 2024, in sheetlet of 10 stamps. This issue can now be reported in the catalogue as a Concerted issue with the entry code [C20240930].

Similarly, the Egyptian counterpart for the Hungarian souvenir sheet issued on November 28, 2024, was discovered. We can therefore confirm that these two sheets from Egypt and Hungary form a joint issue that is described in the catalogue under the heading [T20241128]. The Egyptian souvenir sheet was issued at only 7,000 samples from which 700 were taken to prepare first day covers.

There is an interesting on-going discussion about a potential Italy – Peru joint issue related to the 150th anniversary of diplomatic relations between both countries. On August 28, 2024, Peru issued two stamps, so far without counterpart from Italy. In the 2025 Italian philatelic program, we discover now that Italy intends to issue stamps on January 30, 2025, celebrating the same event, but even claiming it should be joint. Italian Post just informed that there was a delay as they were not ready by the time of issue of the Peruvian stamps. As Peru issued their stamps unilateraly (without joint character claim), this announcement looks surprising. We have not seen the design of the Italian stamp and we will probably have to wait until January 30, 2025 to define the real characters of this stamp and decide afterwards how to consider them. There is one important point however to take in account: there should be no confusion between joint stamps and a joint event. So, decision to integrate these stamps in the catalogue, is still on hold.

The situation is clearer with the Peruvian – Dominican Republic issue. On November 13, 2024, Peru also issued stamps at the occasion of the 150th anniversary of the relationship between both countries. It appears that Dominican Republic issued a single stamp the same day, reproducing the buildings that are reproduced on the Peruvian stamps. In this case we are in presence of a real twin issue that will be described in the catalogue under entry number [T20241113]

In the meantime, a Mauritius – India mixed FDC became available. This item is based on an illustrated Mauritius first day cover celebrating the 200th anniversary of Maharishi Dayanand Saraswati (1824-2024), on which was added an India stamp with exactly the same design itself cancelled from December 12, 2024. By further inquiries about this document, Jaap Sarelse could confirm that this stamp release is not a joint issue. The design was made available by the Organization supporting the anniversary events, which any post office could use to issue a stamp. It happens that both countries used the logo alone to fill the space within the stamp which resulted to very similar items. Collectors created mixed FDCs only on the basis of the stamp similarities, but postal administrations never collaborated. Suriname issued also stamps at this occasion, using only the same portrait but not the full logo.


During this search activity, a new joint issue appeared that has been forgotten so far: Morocco and the United Arab Emirates celebrated historical relationship through identical stamps and souvenir sheets. These stamps were released on November 13, 2024. they represent symbols, flags of both countries, the “Hassan II” Mosque in Casablanca and the “Sheikh Zayed Grand Mosque” in Abu Dhabi.

For all this information, thanks to Ali Ahmed Med Achour (Algeria), Don Birschel (USA), Tolga Caglayankaya (the Netherlands), Enzo Cafaro (Italy), Fabio Bonacina (Italy), Kenneth Sequeira (Singapore), Jaap Sarelse (the Netherlands), Cesar Ittmann (The Netherlands), Eric Chan (Hong Kong) and Eric Contesse (France) through his Facebook blog Joint Stamp Issues (and of course all the collectors participating to this blog).

UPU 150th anniversary

The Universal Postal Union (UPU) is a specialized agency of the United Nations (UN) that coordinates postal policies among member nations and facilitates a uniform worldwide postal system. It comprises 192 member states and is headquartered in Bern, Switzerland. It was established on October 9, 1874, exactly 150 years ago.

Since more than one year, we know that this anniversary will be celebrated with a stamp which common design was proposed by UPU. In the past, the 75th (1949) UPU anniversary was celebrated, but in a non-coordinated way, mainly by colonial entities (British, Dutch and French – D19490704, D19491001, D19491010, D19491018) and the 100th (1974) anniversary with stamps that remained different for all participating countries (N19741009). The same situation happened in 1999, with absence of concertation for the 125th anniversary celebration (N19991009). Eventually, so far, only the 145th anniversary in 2019 (T20191009b) could be considered as a Twin issue.

During this year of 2024, a very large number of countries are participating. In the strict sense, this has to be considered as a true joint issue, even if there was no real cooperation between countries, but a proposal of a design accepted by most of them and translated in a locally adapted stamp, for a large part of them issued at the anniversary date. It is not an Omnibus series, as Omnibus is defined by a central printing, not by the large number of participating countries. The 2024 stamps will be reported in the catalogue as a Twin issue under [T20241009]. It is easily understandable that some joint issues collectors do not integrate such large series in their collection, in the same way Europa-CEPT stamps are not acceptable for them. Each individual collector has to decide on the basis of the following.

In the catalogue, the countries will be divided in subgroups:

  • A: the countries which take the exact original design proposed by UPU and issue the stamp(s) on October 9, 2024 (or actually around this date, plus or minus a week, roughly between October 1 and October 17, 2024), according to the definition of a twin issue [T]
  • B: the countries which take the exact original design but issue the stamp at a different date. It should not be surprising if some countries may issue their stamp in 2025 or even 2026. This is the equivalent of a Concerted issue [C]
  • C: the countries which use only a part of the design, actually integrating only the “150” logo and add some other illustrations. This logo can appear within the stamp, or on the margin of a souvenir sheet or within a label. Those stamps are also considered as twin or concerted issues of Type [T2] or [C2]
  • D: the countries which use a completely different design, but still issue their stamp(s) around October 9, 2024. This is the equivalent of a Parallel issue [P]. In this case, the original logo may appear on the stamp, but at a size that remains smaller than the half of the surface of the stamp
  • E: finally the countries that do not want to stick to design and date, and work on their own, just referring to the UPU anniversary. These countries are simply listed, without details, as they cannot be considered as joint [N].

We will have again to take care of stamps that are created by agencies that are producing stamps for certain countries but which have been given the freedom to issue stamps without a real control from the reference countries. These stamps are easily recognized by the number of stamps issued in a series and they are produced to fool collectors. In order to better identify these stamps and because they remain real stamps but never reach the originating country, they will be reported in the catalogue, but in italics. In the same way, some other stamps such as the French stamp with a full common logo are of private origin (personalized stamp) that cannot be considered as part of this joint issue either. This will be true for any other privately produced stamp from other countries, if any, and also described in italic characters.

The countries for which we already have information are reported below. If a date between brackets is missing behind the country name, this means that this stamp(s) was issued on October 9, 2024. If the content of the brackets remains empty, this means that the exact issue date is not known yet. A large number of images were provided by Enzo Cafaro (Italy). The following list is of course not yet complete.

Countries of type A (Twin [T1]): Algeria – Andorra (French) (October 10) – Andorra (Spanish) – Armenia – Bangladesh – Belarus – Bosnia Herzegovina (Bosnia) – Brazil – China (PR) – Croatia – Cyprus – Dominican Republic – Greece – Guernsey – India – Indonesia – Ivory Coast – Jordan – Latvia – Lithuania (October 4) – Mauritius – Moldova – Myanmar – Paraguay – Peru – Romania – Sri Lanka – Thailand – Turkmenistan (October 8) – Ukraine – United Arab Emirates

Countries of type B (Concerted [C1]): Argentina (August 28) – Azerbaijan (February 1)Burundi (September)Central Africa (September)Djibouti (September) – Georgia (June 1) – Guinea (September)Guinea-Bissau (September)Liberia (September)Mali (September) – Monaco (May 30) – Mongolia (September 25) – Sierra Leone (September)Togo (September)

Countries of type C (Twin or concerted [T2] or [C2]): Bosnia (Serbia) – Egypt () – France (October 14) – Hong Kong – Hungary (July 24) – Isle of Man (August 30) – Japan – Kyrgyzstan (October) – Luxembourg (September 10) – Macau – Malaysia – Morocco – Pakistan – Portugal – San Marino – Saudi Arabia () – Singapore – Slovenia – Spain – Syria – Tunisia – Türkiye – Uruguay – Uzbekistan () – Vietnam

Countries of type D (Parallel issue [P]): Australia (October 1) – Austria (October 4) – Brunei Darussalam () – Bulgaria – Czech Republic – French Polynesia – Germany (October 10) – Macedonia (North) – Mexico – Montenegro – Qatar () – Russia – Slovakia – Switzerland (September 5) – Tajikistan (May) – Vatican (September 16) – Wallis and Futuna

Countries of type E (not considered as joint): Belgium (June 10) – Serbia (May 25) – United Nations – Geneva (May 30) – United Nations – New York (May 30) – United Nations – Vienna (May 30).

So far, 86 countries are listed above to which one has to add 2 postal authorities that have issued stamps that cannot be considered as joint (Type E – United Nations offices are not taken in account as countries, UPU being a sub-unit of the United Nations). The UPU counts presently 192 members, which means information from 106 countries (!) is missing. Obviously there will be an update of this page. A great help is needed here to recover information from other participating countries. We are also missing better quality images for stamps from Ivory Coast and Ukraine. Thanks a lot in advance for providing name of missing countries, exact dates of issue, and when possible illustrations, printing runs, sizes of panels and by-product lists.

The catalogue pages should be updated within the next week.

Update February 2023

On February 28, 2023, the joint issue between Armenia and Slovakia was released as scheduled. It celebrates the 30th anniversary of relationship and the stamps depict the Tatev Monastery, in Syunik region (Armenia) built during the ninth century, included now in the UNESCO World Cultural Heritage list and the St George’s Church, in Nitrianska Blatnica (Slovakia) also from the ninth century. The particularityy of this issue comes from the way the stamps are produced. The stamps are printed in a pane size [5×9] containing both stamps, type A in the top half, type B in the bottom half, together with 5 central labels forming a central cross. The overall structure looks the following: 3 rows of 5 stamps A, a row containing 2 pairs of stamp A separated by a label, then a row with one stamp A, three labels and one stamp B, and a row containing 2 pairs of stamp B separated by a label, and at the bottom 3 rows of 5 stamps B. This structure leads to a sheet containing 20 stamps A, 20 stamps B and 5 labels. Each sheet can contain vertical pairs of se-tenant A-B stamps, but limited to two units per pane. Knowing that the total printing of stamps is 2×20,000 for Armenia and 2×100,000 for Slovakia, only respectively 1,000 and 5,000 panes have been printed containing a maximum of 2,000 and 10,000 vertical pairs respectively.

These miniature sheets could be cut a different way, by keeping in one piece the five central labels with the 2 stamps A and 2 stamps B in the four corners. Only a maximum of 1,000 units for Armenia and 5,000 for Slovakia of these cut outs of printed panels can theoretically exist. The central labels represent the flags of both countries, and the coat of arms of Armenia, respectively Slovakia. The two other labels contain the words ‘Armenia – Slovakia joint issue’ in English and Armenian for Armenia, in Slovak and Armenian for Slovakia.

Jaap Sarelse (The Netherlands) provided some information about the potential Cambodia-South Korea joint issue that was supposed to be released on February 10, 2023. The original source was the South Korean Philatelic Service. However, Jaap learned from two Cambodian sellers that no such an issue is mentioned in the 2023 list of Cambodian stamps. Also a seller from South Korea confirmed this is not a joint issue. The top margin of the souvenir sheet printed by South Korea is entitled “Protecting Endangered Species in Korea – Cambodia REDD+ Joint Project Area”, meaning the ‘joint’ character is refering to an area between both countries, and a common project, but not to this stamp issue. This entry is removed from the catalogue.

Don Birschel (USA) reports also about stamps released at the occasion of the Kuwait 62nd national day by both Kuwait (February 22, 2023) and the United Arab Emirates (February 25, 2023). Even if the Kuwait 62nd national day is celebrated by the UAE, there are no hints of collaboration between both countries and stamps are different. These cannot be considered as a joint issue.

A surprising joint issue between India and Luxembourg will be released on March 14, 2023. The information was first provided by Souvik Ghatak (India) and Kenneth Sequeira (Singapore). The Luxembourg post made the announcement as early as March 2, 2023, but it took some time for India to confirm, despite the fact that the designer of the miniature sheet is of Indian origin. The stamps relate to the 75th anniversary of the relationship between both countries and is illustrated by sculptures by Amar Nath Sehgal (1922-2007), an Indian sculptor, painter and poet who spent a large part of his life in the Grand Duchy of Luxembourg.

Up to now, there are no news from the Israel-India issue supposed to be released in the course of the month of February. In the meantime, however, the first image of the Israel stamp to be realeased on April 4, 2023 jointly with Cyprus was released. Topic is aerial firefighting. The Cyprus stamps has not been seen so far.


The following information has been added to or modified in the new version of Volume 15 (Vol 15 V4.03):

  • The above mentioned Armenia – Slovakia issue [T20230228] as well as the Poland – Slovenia [T20230306], the Poland – Vatican [T20230227] and the Ascension – British Antarctic Territories – Falkland Islands – South Georgia – Tristan da Cunha [D20230215] stamps have been integrated in the catalogue
  • Confirmation of the existence of mixed FDCs for the 2022 Argentina – Spain Juan Domingo Peron issue [C20220914]
  • Update of the list of new issues including Pakistan – Sri Lanka (2023), Japan – Peru (August 21, 2023), Japan – Vietnam (September 21, 2023)

The information related to complete descriptions of new sets of joint issues is also dispatched in Vol 1. Note that the page “Philatelic resources” is constantly updated to maintain the most accurate level (which is not easy, corrections and additions welcome) and changes will not be reported here.


50 Years of Egyptian – Emirati Relations

Two flags, the figure “50” and a logo illustrate the common stamps of the EgyptUnited Arab Emirates issue celebrating the 50 years of bilateral relations between both countries. These twin stamps were released on January 19, 2023 in form of souvenir sheets with a single stamp. We are still missing details such as printing runs and size, but it seems these items are quite large (estimated 100×80 mm for Egypt and about 80×56 mm for UAE) (Information provided by Kenneth Sequeira, Singapore and Don Birschel, USA).


This issue has of course been added in the catalogue Vol 15. Some collectors asked for getting some details about the information updated in each catalogue when replacing a previous edition, as it is not obvious to see in a quick way what really was modified or added. We will try to supply this information whenever relevant at the end of a post like this one to help improving this identification. Here is the first set of information related to the modified content appearing in Vol 15 V4.02:

  • The new Egypt Emirati joint issue described above [T20230119]
  • Confirmation of the existence of mixed FDCs for the 2022 Romania – SMOM issue [N20220916], the mixed crypto stamp FDC from Austria and the Netherlands [T20220922], as well as for the older Colombia – Indonesia issue from 2020 [T20200915] (all mixed items produced and provided by Jaap sarelse – The Netherlands)
  • Introduction of the new Ecuador souvenir sheet in the joint issue [T20220728]
  • Update of the list of new issues to be released during 2023, mainly involving Morocco and Slovakia

Note that the page “Philatelic resources” is constantly updated to maintain the most accurate level (which is not easy, corrections and additions welcome) and changes will not be reported here.


Arab League countries latest issues

Kenneth Sequeira (Singapore) was the first to discover and provide all pictures from the most recent GCC Arab countries stamps. Starting on December 12, the six countries Bahrain (), Kuwait (December 21), Oman (December 13), Qatar, Saudi Arabia () and the United Arab Emirates (December 12) issued the same souvenir sheet portraying the 6 Heads of States and a stamp showing the flags and one building from these states. These stamps were issued to commemorate the 40th anniversary of the Gulf Cooperation Council.

In a previous blog, we announced the issue of a common stamp created by the Arab Postal Union on the basis of a Qatar model to celebrate the FIFA Soccer World Championcup organized in Qatar. Only little information came through so far, but Mohamed Essawy (Egypt) and Ali Ahmed Med Achour (Algeria) could provide the first pictures of stamps from Jordan and Oman, apparently issued on December 18, 2022. We have to continue looking for similar stamps issued by other countries belonging to the Arab Postal Union, as this series is definitely not complete.

Algiers Summit 2022 (2)

The 2022 Arab Postal Union Algiers Summit took place on November 1 and 2, 2022 as announced. A stamp with a common design was supposed to be released by most of the participating members. Unfortunately, the information remains difficult to obtain. Most of the below was obtained from our friend Med Achour Ali Ahmed (Algeria), but the list still seems uncomplete.

So far, we had already reported about the following countries which had issued a stamp each: Egypt (August 3, 2022), Algeria (August 20, 2022), Oman (October, 2022), Djibouti (October 9, 2022) and Tunisia (October 25, 2022).

To this previous list, we can now add Iraq, Jordan, Palestine, Saudi Arabia, and United Arab Emirates, all of them having issued stamps on November 1, 2022.

These stamps represent 10 countries out of the 22 member states of the Arab League. So, another 12 potential participants could still participate or even may already have issued stamps. These include: Bahrain, Comoros, Kuwait, Lebanon, Libya, Mauritania, Morocco, Qatar, Somalia, Sudan, Syria, and Yemen. Story to be followed …

2022 UAE-India issue delay to be explained

Jaap Sarelse (the Netherlands) just provided a sample of the first day cover of the UAE stamps, dated June 30, 2022. Stamps from this country were supposed to be released at the same date as the Indian counterpart, namely on February 18, 2022. Actually, a long unexplained delay affected the release of this UAE issue. As a consequence, in the catalogue, this joint issue has to be re-attributed the category of Concerted [C] issue and is now filed under [C20220218] instead of [T20220218]. By looking closer it appears that the design of the final UAE product is also slightly different from what was presented in the February 2022 project, in particular regarding the building depicted in the margin of the souvenir sheet. Take a look below on the illustrations to see the differences in lengths and position of texts in the margin (four lines instead of three) but also on building representations and compare them to the issued Indian souvenir sheet. The delay was probably not only due to logistics issues, but also to the agreement needed from India regarding the depicted buildings. In other words, it may be possible that the UAE stamps had to be reprinted due to this design mistake. We do not know if the first design was printed on time and needed to be destroyed. There is a need to dig further and any information is welcome.

UAE FDC cover dated June 30, 2022
Original February 2022 UAE project – not released (wrong building on the bottom right side)
Final design of the UAE souvenir sheet issued on June 30, 2022
Indian souvenir sheet issued on February 18, 2022, for comparison

Unexpected UAE – India relationship issue

Discovered by Don Birschel (USA) and confirmed by Kenneth Sequeira (Dubai), here is an unexpected joint issue linking the United Arab Emirates with India and released on February 18, 2022 at the occasion of the 50th anniversary of their relationship. Both countries offer a nice souvenir sheet with flags, but also governmental buildings. Actually, this souvenir sheet refers to the celebration of the Year 2022 of the 50th anniversary of the UAE’s formation and the 75th anniversary of the independence of India.

This was also the occasion to update Catalogue 15 – 2022-2024 V3.04.
