How many countries does Mexico border?

Mexico borders three countries: the United States to the north, Belize to the southeast, and Guatemala to the southeast. This makes Mexico a multi-border country, linking it to Central America and North America. The United States-Mexico border is one of the most significant and frequently crossed international borders globally, spanning approximately 3,145 kilometers (1,954 miles) from the Pacific Ocean to the Gulf of Mexico. The borders with Belize and Guatemala are shorter but still contribute to Mexico's overall land boundaries.
