Rules note: You need an FCC license to transmit on GMRS (47 CFR 95.1705). Use only FCC-certified GMRS radios, and stay within the power and channel limits for your station type. This is general information, not legal advice. The eCFR text of Part 95 Subpart E is the authority.
Many low-cost UHF handhelds can be programmed to many UHF frequencies, including the GMRS channels. That doesn’t make them legal GMRS radios. The FCC rules here are short and strict.

The three rules that decide it
- Only certified transmitters may be used. “No person shall operate a transmitter in any Personal Radio Service unless it is a certified transmitter,” one certified for that service. Using a non-certified transmitter “voids the user’s authority to operate that station” (95.335).
- GMRS radios must be certified for GMRS. “Each GMRS transmitter … must be certified” under Subpart E and Part 2 (95.1761(a)).
- GMRS certification excludes ham capability. “No GMRS transmitter will be certified for use in the GMRS if it is equipped with the capabilities to operate in services that do not require equipment certification, such as the Amateur Radio Service” (95.1761(c)).
Put together: a radio built to transmit on amateur bands can’t hold a GMRS certification. Transmitting with it on GMRS channels uses a non-certified GMRS transmitter.
Does a ham license change anything?
No. A ham license authorizes amateur operation under Part 97. GMRS needs its own individual license (95.1705) and a GMRS-certified radio (95.335). The FCC notes that its equipment authorization program “does not generally apply to amateur station transmitters” (FCC). That’s exactly why those radios don’t qualify for GMRS.
Modifying radios
- No unlocking or “opening up” GMRS radios. No one may modify a Personal Radio Service transmitter in a way that causes a rule violation, such as adding transmit frequencies, raising power or changing modulation. Such a modification “voids the certified status” (95.337).
- Controls must be internal. GMRS frequency-determining circuitry and programming controls must not be accessible from outside the radio (95.1761(c)).
- No add-ons that break the rules. You may not operate a transmitter with an external device that causes a rule violation (95.339).
Sellers have obligations too
No one may manufacture, import, sell or offer for sale non-certified equipment for the Personal Radio Services, with narrow exceptions (95.391). A listing that says “GMRS compatible” isn’t the same as an FCC grant. You can check the grant yourself; see how to check a GMRS radio’s FCC ID.
What to buy instead
- For GMRS: a radio whose FCC grant lists Part 95 GMRS (Part 95 Subpart E). Check before you buy and compare current prices: Shop gmrs radio on Amazon →.
- For ham bands: keep the amateur radio for amateur frequencies under your ham license.
- For both: two radios. There’s no legal single-box answer for transmitting on both services, and combination GMRS/FRS radios have also been banned from sale since September 30, 2019 (95.1791).

FAQ
Can I listen to GMRS on a ham radio? The certification rules (95.335, 95.1761) apply to transmitters.
What about emergencies? Any GMRS channel may be used for emergency communications (95.1731(a)), but 95.335 has no general emergency exception; the GMRS exception section it cross-references (95.1735) is reserved in the current rules. Plan ahead with certified radios; see GMRS for emergencies.
My radio came “GMRS unlocked.” Is that okay? If it can transmit on amateur bands, it can’t be certified for GMRS under 95.1761(c). Check its FCC ID.
