On a shotgun, where is the serial number typically located?

The serial number of a shotgun is typically found on the receiver. This is where the primary components are housed, including the trigger mechanism and action. The receiver acts as the central part of the shotgun, connecting the firing mechanism to the barrel and stock. The Federal law mandates that all firearms, including shotguns, must have a unique serial number for identification purposes, and placing it on the receiver ensures that it is both accessible for recordkeeping and protected within the firearm's structure.

While other parts such as the barrel, trigger guard, or fore end could potentially bear markings or information, they do not serve as the standard location for the serial number due to considerations of safety, accessibility, and compliance with regulations surrounding firearm manufacturing and tracking.
