Family Radio Service

Overview
The Family Radio Service (FRS) is in the 462-467 MHz spectrum range. The most common use for FRS spectrum is short-distance, two-way communications using small, portable hand-held devices that function similar to walkie-talkies. The Family Radio Service (FRS) dates back to 1996 when the FCC authorized the use of 14 channels within the General Mobile Radio Service (GMRS) for use by FRS.

The FRS is licensed by rule. This means an individual license is not required to operate an FRS device. You can operate an FRS device regardless of your age and for personal or business use so long as you are not a representative of a foreign government.

The FCC service rules for the Family Radio Service (FRS) are located in 47 C.F.R. Part 95.
