List of Canada–United States border crossings

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.
