Compulsory ID cards
Non-compulsory ID cards
This is a list of identity document policies by country.
A national identity document is an identity card with a photo, usable as an identity card at least inside the country, and which is issued by an official authority.
Driver's licenses and other cards issued by state or regional governments indicating certain permissions are not counted here as national identity cards. So for example, by this criterion, the United States driver's license is excluded, as these are issued by local (state) governments.
