GMRS vs FRS: same channels, different rules
We research products from makers' specs, manuals and safety agencies; we do not run hands-on tests. Links to Amazon may earn us a commission at no cost to you. How this works.
Quick answer
FRS and GMRS radios share the same 22 channels, but the rules differ. FRS is license-free, limited to 2 watts on most channels and 0.5 watt on channels 8 to 14, with a fixed antenna. GMRS needs an FCC license, but allows up to 50 watts on mobile and base radios, external antennas and repeaters for more range. Buy FRS for simple family use without paperwork; buy GMRS when you need distance and are willing to get the license.
FRS and GMRS side by side
| Rule | FRS | GMRS |
|---|---|---|
| License | None; FCC calls it licensed by rule | Individual FCC license; new licensees must be 18 or older |
| Channels | 22, all shared with GMRS | 30: 16 main and 14 interstitial |
| Power limit | 2 W ERP on channels 1 to 7 and 15 to 22; 0.5 W on 8 to 14 | Up to 50 W output for mobile and base stations on main channels; 5 W ERP on 462 MHz interstitials; 0.5 W on 467 MHz interstitials |
| Antenna | Built in, not removable | Not bound by the FRS built-in antenna rule |
| Repeaters | No | Yes, on the 467 MHz main channels |
| Identification | No call sign, since no license is issued | Call sign at the end of transmissions and every 15 minutes |
| Text and location data | Brief texts and location allowed | Brief texts and location allowed |
All rule details come from FCC Part 95 and FCC's service pages.
Channels: why FRS and GMRS radios can talk
- Shared frequencies: FCC says all 22 FRS channels are also allotted to GMRS, so an FRS radio and a GMRS radio on the same channel and privacy code can hear each other.
- Channels 8 to 14: these 467 MHz interstitial channels are capped at 0.5 watt for both services.
- Repeater inputs: GMRS adds eight 467 MHz main channels that handhelds and mobiles use only to talk through a repeater, plus brief test transmissions.
- Etiquette: FCC describes FRS channel sharing as listen-before-talk, so check that a channel is quiet before you transmit.
Range: power, antenna and repeaters
- Power: a GMRS mobile or base radio may run up to 50 watts on main channels, while an FRS radio is capped at 2 watts ERP. More power helps, but terrain and buildings matter more.
- Antenna: FRS antennas must be integral, with gain no higher than a half-wave dipole; GMRS radios can use a better, higher antenna such as one on a vehicle roof.
- Repeaters: a GMRS repeater on a hill or tower retransmits your signal over a wider area. See our Midland GMRS radio guide for repeater-capable MicroMobiles.
- Advertised miles: mileage claims on boxes assume open, unobstructed areas; Midland marks its FRS 30-mile figure with an asterisk.
Getting a GMRS license
- Who: FCC rules require an individual license to operate a GMRS station, and new licensees must be at least 18.
- Family: FCC says the license covers the licensee's immediate family members.
- Term: FCC lists a 10-year license term.
- On the air: say your call sign at the end of a transmission or series of transmissions, and at least every 15 minutes during long ones.
FRS needs none of this, which is why FRS radios are the simplest choice for kids and casual family use.
Which should a household buy?
- Neighborhood, campsite, store aisles: FRS handhelds are enough and need no license.
- Farms, rural properties, convoys: GMRS with a mobile radio and a vehicle antenna, plus handhelds for people on foot.
- Outage plans: both can carry NOAA weather alerts on many models; Midland's FRS LXT600 and GMRS GXT1000 both list weather alerts.
- Mixed groups: FRS and GMRS radios interoperate on the shared channels, so licensed family members can use GMRS while kids use FRS.
