GMRS: The General Mobile Radio Service (GMRS) is a land-mobile FM UHF radio service designed for short-distance two-way communication. Licensed.
FRS: The Family Radio Service (FRS) is a mobile radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band. Unlicensed.
FRS/GMRS Channels
Channel numbers commonly used on 22 channel FRS/GMRS dual service radios. Most radios of this type are not capable of repeater operation and do not include the repeater input frequencies.

Midland Extra Channels
Midland has started marketing "Extra Channels" on several of their radios. These extra channels are simply existing FRS/GMRS frequencies with hard coded tones and low power on the FRS-only channels.

GMRS
GMRS radios operate on 8 UHF frequencies that were set aside by the FCC for family use. A license is required ($85.00 for a five year term) which covers your entire family, including (grandparents, parents, brothers, sisters, cousins, aunts, uncles, in-laws, sons, daughters, and pretty much any one related by blood or marriage). The purpose is to facilitate the communications of families over a limited distance.
Applying for a GMRS license should be done online.
Ham radio license does NOT cover the GMRS frequencies.
FRS
FRS radios use narrow-band frequency modulation (NBFM) with a maximum deviation of 2.5 kilohertz. The channels are spaced at 12.5 kilohertz intervals.
FRS radios are limited to 500 milliwatts.
FRS stations on channels 1 through 7 may communicate with GMRS stations on those shared channels; the GMRS stations may use up to 5 watts of power, while the FRS stations are restricted to 500 milliwatts.
FRS radios must use only permanently attached antennas, such as walkie-talkies; there are also table-top FRS "base station" radios that have whip antennas. This limitation intentionally restricts the range of communications, allowing greatest use of the available channels. The use of duplex radio repeaters and interconnects to the telephone network are prohibited under FRS rules.
Despite manufacturer advertising claims range is typically less much less than a mile.
