AM

The two-character ISO 3166 country code for ARMENIA.

AM

1. ISO 3166-1 alpha-2 code for the Republic of Armenia. This is the code used in international transactions to and from Armenian bank accounts.

2. ISO 3166-2 geocode for Armenia. This is used as an international standard for shipping to Armenia. Each Armenian region and the city of Yerevan have their own codes with the prefix "AM." For example, the code for the Province of Ararat is ISO 3166-2:AM-AR.
