In order to provide tagging marks on the shell of bullets fired through the barrel of firearms, the invention suggests a firearm barrel (1) with means for providing identification bar code on the shell of bullets fired through the barrel, said barrel (1) comprising a rifled or smooth bore (2), wherein the barrel (1) comprises marker pins (6) circumferentially arranged in the barrel (1) under different angles ( alpha i, beta i) in relation to a reference angle position (0 DEG ), said marker pins (6) penetrating into the bore (2) of the barrel (1) up to its base diameter (d), and being capable of producing bar code markings on the shell of the bullet. The identification marks put on the bullets enable easy and reliable identification of any firearm recorded with an appropriate registration system.
