What is GMRS?

The General Mobile Radio Service (GMRS) is a licensed two-way radio service in the United States, authorized by the FCC under Part 95 of its rules. It operates on UHF frequencies in the 462 and 467 MHz range and is designed for short-distance personal and family communications. Unlike CB radio or walkie-talkies from a toy store, GMRS gives you real power, real range, and access to a nationwide repeater network.

How it compares to FRS and ham radio

GMRS sits between the completely license-free FRS (Family Radio Service) and the exam-required world of amateur (ham) radio. Understanding the differences helps you pick the right service for your needs - see our full GMRS vs. FRS vs. Ham comparison for details.

• FRS is license-free but capped at 2W on most channels with no external antennas allowed. GMRS and FRS share channels 1–22, so FRS and GMRS radios can talk to each other on those channels.
• Ham radio requires passing a written exam (even the entry-level Technician test covers electronics and regulations). Ham offers enormous frequency flexibility but is overkill for most people who just want reliable everyday comms.
• GMRS requires a license but no exam. One $35 license covers your entire immediate family for 10 years. You get more power, external antennas, and repeater access that FRS can never touch.

Who uses GMRS

GMRS attracts a wide range of users - it's practical enough for casual family use but capable enough for serious applications:

• Families and neighborhoods - coordinating at theme parks, events, or around a large property
• Overlanders and off-roaders - vehicle-to-vehicle comms on the trail where cell service doesn't exist
• Preppers and emergency prep groups - reliable fallback when cell networks are down or overloaded
• Campers and hikers - staying in touch across a campground or between split groups on a trail
• Community networks - some neighborhoods and towns coordinate local repeater systems for day-to-day use
• Event staff and volunteers - sporting events, races, festivals, and fairs where cell-based push-to-talk apps aren't reliable

The 30 GMRS channels

GMRS has 30 designated channels across the 462/467 MHz band. Channels 1–7 and 15–22 are shared with FRS. Channels 8–14 are low-power FRS-only (interoperability only). Channels 15–22 are the higher-power GMRS simplex channels. Channels 23–30 are GMRS-only repeater output/input pairs.

See the full channels and frequencies guide for a complete channel chart with power limits and usage notes.

Repeaters and extended range

One of GMRS's biggest advantages over FRS is legal access to repeaters. A repeater is a radio station - usually mounted on a hill, tower, or building - that receives your signal and instantly re-transmits it at higher power. A single repeater can give handheld radios coverage across an entire metro area or mountain range.

Many GMRS repeaters are community-owned and open to licensed users. Some require a tone code (CTCSS) to access. Learn more in our repeater guide.

Getting licensed

The GMRS license application takes about 15 minutes on the FCC's website. There's no exam - you fill out the form, pay $35, and you're licensed for 10 years. Your license covers you and your immediate family members per 95.1705(c)(2) — a broad list including spouse, children, parents, siblings, grandparents, aunts, uncles, nieces, nephews, and in-laws.

See the step-by-step walkthrough in our getting licensed guide.

What equipment do you need

To get on GMRS you need a Part 95-accepted radio - not just any radio that happens to transmit on those frequencies. Most major brands (Midland, Wouxun, Baofeng with GMRS-specific models, Radioddity) sell FCC-accepted GMRS handhelds. For vehicle or base station use, mobile radios offer more power and better antenna options.

Prices range from around $30 for a basic pair of handhelds to $150+ for a capable mobile radio. You do not need an expensive setup to get started. Our radio buying guide covers the categories and what to look for.

The GMRS community

GMRS has a growing community of enthusiasts who go well beyond family walkie-talkie use. There are GMRS nets (scheduled on-air check-ins), regional repeater groups, and active online forums. If you're looking for repeaters near you, local nets, or clubs to connect with, our finding communities guide points you in the right direction.
