Quick Scoop

  • The long, formal name is used in the constitution, on some official documents, and in diplomatic contexts.
  • In everyday speech, people almost always just say “Mexico,” and that short name is widely used around the world.
  • The official name has been in place since the first federal constitution of 1824 and was kept in later constitutions, including the current one from 1917.
  • There have been political proposals (for example in 2012) to change the official name simply to “Mexico,” but they have not been adopted.

So: on passports and in legal-constitutional terms it is the United Mexican States , but in daily life and most media, it’s just Mexico.

TL;DR: The country’s official name is United Mexican States (Estados Unidos Mexicanos), but almost everyone simply calls it Mexico.
