Mexico–United States border The Mexico–United States border (Spanish: Frontera entre Estados Unidos y México) is an international border separating Mexico and the United States, extending from the Pacific Ocean to the west and Gulf of Mexico to the east. The border traverses a variety of terrains, ranging from major urban areas to uninhabitable deserts. Approximately 350 million documented crossings occur annually,[1][2] and is the most frequently crossed border in the world.[3][1][4]
