The Border Guard Command, commonly known as NAJA Border Guard is a subdivision of the Law Enforcement Force (NAJA) that performs border guard and border control duties for land borders, and coast guard duties for maritime borders. Between 1991 and 2000, border control was the responsibility of the Security deputy of NAJA. Prior to 1991, border control was the responsibility of the Gendarmerie.
In June 2020, Ahmad Ali Goudarzi was appointed as the chief commander NAJA Border Guard.
