However, not all devices approved for sale and operation by the FCC rules require an FCC ID number.
These rules also require that labels with the information prescribed by the FCC be affixed or accompany the device. The FCC rules require that most devices be authorized before they can legally be imported or sold in the United States.
Check the instruction in the User Manual to find the FCC ID information. If a device has a built-in display, the FCC ID may be provided electronically.
