Is an FCC ID a Serial Number?
FCC IDs themselves are not serial numbers, but they can contain serial numbers. The first 3 to 5 characters of an FCC ID are chosen by the Federal Communications Commission. This is the body that approves the FCC ID certification numbers. The remaining characters of the FCC ID may be the same as the serial number or model number of the device.
Serial numbers tend to be unique for each device, that is, a new serial number will be made for each device coming off the manufacturing line. FCC IDs, however, are unique for all of the same models coming off the manufacturing line. In this way, an FCC ID is much similar to a model number than a serial number. If an FCC ID begins with a 2, the first 5 characters of the code are the “business registration ID / Grantee Code” and the remaining numbers may be the model number. If the FCC ID does not begin with a 2, only the first 3 characters make up the grantee code.
