Ther are 48 places where one can legally cross between the United States and Mexico. These places are known as Ports of entry. These Ports of Entry are official crossing points where U.S. Customs and Border Protection (CBP) officers
regulate the flow of people and goods between the United States and Mexico. Along the vast U.S.-Mexico border, some ports of entry lie hundreds of miles apart. Some ports are only for commercial trucks, hauling cargo between the two
countries; some are rail crossings, where only trains are allowed to cross.
Of the 48 total ports, only the 24 depicted on the map above had travelers cross on foot in September 2018. The map shows that typically larger number of travelers enter on foot closer to large cities, and that number is smaller at the
more remote ports. Foot traffic at the ports has historically been commuters and those coming to visit famiy; however, in recent months, the number of asylum seekers arriving both at and between the ports has been growing.
The numbers are reported to the US Department of Transportation by Customs and Border Patrol Office of Field Operations agents. The number of outbound pedestrians is not tracked by the US CBP, as they are counted by the Mexican
authorities.
