Inclusion of United States in Name by Country 2025

While we tend to think of the United States of America when we hear the words “United States,” you might be surprised to learn that the USA isn’t the only one bearing the phrase.

Inclusion of United States in Name

At this time, there are 2 countries that include the words “United States” in their official name:

• United States of America
• United States of Mexico/United Mexican States

These neighboring countries are both located on the North American continent and share a border along the United States of America’s southern region and Mexico’s northern region.

Both countries feature independent states that operate like miniature countries-within-a-country, all united under each entity’s federal government.

The United States of America includes 50 states under the federal union with 48 of those residing directly inside the physical borders of the country.

Two states, Alaska and Hawaii, are noncontiguous and lie outside the United States of America’s borders but are still united with the other 48 by the federal government.

The United States of Mexico includes 32 independent states (technically 31, since the capital, Mexico City, isn’t considered a true state) bound and united by the Mexican federal government.

Why Do Countries Include United States in Their Names?

Including the words “United States” in a country’s name is no accident. These words carry meaning and that meaning doesn’t apply to every country.

For a country to bear the words “United States” in the official name, the country should feature a group of independent states that share a federal government to unite them all.

This is why many countries include the word “United” in their name, but only 2 include “United States.”
