An Extraterritorial Office of Exchange (ETOE) is a facility belonging to a postal operator outside its national territory on the territory of another country. There are ETOE’s in the United States belonging to Deutsche Post (Germany), New Zealand Post, Sweden Post, Swiss Post (Switzerland), and Emirates Post (UAE).
The U.S. Department of State regulates the operation of ETOE’s in the United States.
An ETOE may serve the needs of the postal operator to which it belongs by acting on either inbound or outbound shipments of mail to/from the country in which it is located.
Commercially, an ETOE will typically assist the foreign postal operator in gaining postal revenue from businesses and other senders of mail from the territory in which it is located. For this reason, ETOE’s are usually seen as competing with the local postal administration.
