List of entities that have issued postage stamps
This is a
list of entities that have issued postage stamps at some point since
1840. The list includes any kind of governmental entity that issued a distinct type of stamp, including post offices in foreign countries, military occupations, colonies, and city-states. The list excludes the current members of the
UPU that are listed at
postal organizations.
Philatelists and stamp collectors often refer to the entities no longer issuing stamps as dead countries.
The dates are the generally-agreed-upon dates of first and last stamp issues (which may not match the years of existence).
