A
border checkpoint is
a place, generally between two countries, where travelers or goods are inspected. Authorization often is required to enter a country through its borders. Access-controlled borders often have a limited number of checkpoints where they can be crossed without legal sanctions. Arrangements or treaties may be formed to allow or mandate less restrained crossings (e.g. the
Schengen Agreement). Land border checkpoints (land ports of entry) can be contrasted with the
customs and
immigration facilities at
seaports,
international airports, and other
ports of entry.
