The official name of the border between the United States and Canada is the International Boundary. This border is the longest international border in the world, stretching approximately 8,891 kilometers (5,525 miles) from the Atlantic Ocean to the Pacific Ocean.
The International Boundary is marked by various monuments and markers, and it is maintained by the International Boundary Commission (IBC). The IBC ensures that the boundary is clearly defined and free from obstructions. The border is not only a political boundary but also a symbol of the peaceful relationship between the two neighboring countries.
