Where is the serial number located on a shotgun?

The serial number of a shotgun is typically located on the receiver. This is a standardized location for serial numbers on firearms as it allows for easy identification and compliance with regulations. The receiver houses the operating parts of the shotgun, and it is the part that is considered the firearm itself from a legal standpoint. Therefore, any legal registration or identification is centered around the receiver.

Although other components like the barrel or stock might have their own part numbers or manufacturer markings, the serial number, which is essential for tracing ownership and legality, is primarily found on the receiver. This helps facilitate tracking and storage of vital information about the firearm throughout its lifecycle.
