This is a list of border crossings along the Canada–United States border, ordered from west to east (north to south for Alaska crossings). Several crossings are along major highways. Some crossings in remote areas are unstaffed; among those, some require travelers to report to border officials at another location, and some may not have any reporting requirement at all.
On the U.S. side, the Department of State assigns a three-letter Port of Entry code to each crossing. This code is included on the passport entry stamp or parole stamp one receives when crossing into the U.S. One code may correspond to multiple crossings.
Land ports of entry
Port of entry hours of service for road crossings, except where noted, are open year-round during the day. The yellow background indicates a border crossing where travel is permitted in only one direction. The green background indicates a border crossing that is located at a bridge or a tunnel.
