Stamp Countries List
From Collectors Collecting Wiki
In the stamps category, the term "country" is loosely used and this list refers to any separate area or region that has issued stamps in the past, present or future.
Colnect currently lists 867 postal administrations on the main page of its stamp catalog. A reorganization process was begun in October 2019 to break apart large "group countries" so that each postal administration had its own separate listing. This process was substantially completed in August 2020, however a few new listings may be added as determined to be needed by the catalog coordinator.
