Most two-way use of a UHF radio in the United States requires a UHF radio license from the Federal Communications Commission, but a few low-power options are exempt. Which license you need depends on how you’re using the radio: GMRS for personal and family use, an amateur license for hobby and experimentation, or a Part 90 business license for commercial operations. Choose wrong and you’ll either waste money or risk an FCC violation.
When You Don’t Need a License
The Family Radio Service is license-free. FRS radios share several channels with GMRS but are capped at 2 watts with fixed antennas, giving a realistic range of roughly half a mile to a mile and a half. If that’s enough for your needs, buy the radio and start talking. No paperwork, no fee.
You cross into license territory the moment you want more power, a detachable antenna, repeater access, or dedicated business channels. Coordinating across a job site, running a farm, or reaching several miles reliably all point to GMRS or a Part 90 license.
GMRS: The Family License
The General Mobile Radio Service, governed by 47 CFR Part 95 Subpart E, is built for individuals and their families. You must be at least 18 and cannot be a representative of a foreign government.1Federal Communications Commission. General Mobile Radio Service Only individuals can hold a GMRS license; businesses and organizations are not eligible and must apply under Part 90 instead.
The big advantage is that one license covers your entire immediate family. Any family member, regardless of age, may operate stations under your call sign.1Federal Communications Commission. General Mobile Radio Service There’s no exam. You fill out the application, pay the fee, and you’re licensed.
GMRS gives you 30 channels, including 8 dedicated repeater channel pairs that FRS radios can’t touch. Mobile, base, and repeater stations can transmit at up to 50 watts on the main 462 and 467 MHz channels, with fixed stations capped at 15 watts.2eCFR. 47 CFR 95.1767 – GMRS Transmitting Power Limits Repeaters are what really separate GMRS from FRS: a 5-watt handheld through a well-placed repeater can cover 20 or 30 miles.
Amateur Radio: License by Exam
Amateur radio opens up a huge amount of UHF spectrum, but you have to pass a written test to get in. The entry-level Technician exam is 35 multiple-choice questions, and you need at least 26 correct (about 74%). General and Extra classes unlock more privileges and require harder exams; the Extra test runs 50 questions and includes 14 schematic questions.
Amateur is strictly non-commercial. You cannot use it to coordinate a business, dispatch employees, or generate revenue. It’s the right choice for technical experimentation, emergency communication, and long-distance work using voice, digital, and satellite modes. During genuine emergencies, amateur operators may use any means available to send essential information, even outside their normal frequencies.3eCFR. 47 CFR Part 95 Subpart E – General Mobile Radio Service GMRS and business licensees don’t have that flexibility.
Part 90: Business and Industrial Use
Organizations that need private radio channels for commercial operations apply under 47 CFR Part 90 through the Industrial/Business Radio Pool. Eligible entities include commercial businesses, educational and religious institutions, hospitals, and medical associations.4eCFR. 47 CFR 90.35 – Industrial/Business Pool This is the path for dispatching delivery drivers, coordinating construction crews, or managing warehouse logistics.
Frequency Coordination Is Required
Part 90 applications include a step that personal licenses skip: frequency coordination. Before the FCC will process your application, an FCC-certified coordinator has to review your power, antenna height, terrain, and existing users in your area and recommend a frequency that minimizes interference.5eCFR. 47 CFR 90.175 – Frequency Coordinator Requirements New assignments, changes to existing facilities, and temporary-location operations all require this showing. Coordinators charge their own fee on top of the FCC’s, and they typically file the application on your behalf.
Business applicants file Form 601, which asks for detailed technical information about station locations, antenna structures, transmitter power, and frequency assignments.6Federal Communications Commission. FCC Form 601 Most businesses work through a dealer or coordinator to get the technical details right.
How to Apply
Every applicant starts in the same place: the Commission Registration System (CORES). Create an FCC Username, register for a 10-digit FCC Registration Number (FRN), and use that number for every filing, payment, and authorization going forward.7Federal Communications Commission. Commission Registration System for the FCC
GMRS and amateur applicants use Form 605, the quick-form application for personal radio services.8Federal Communications Commission. FCC Form 605 The radio service code for GMRS is ZA.9Federal Communications Commission. Personal Service and Amateur Application Fees Business applicants file Form 601. Both are filed electronically through the Universal Licensing System.
Your license information becomes part of a public database. The FCC’s ULS records are freely searchable, so your name, call sign, and address are visible to anyone who looks. Some licensees use a P.O. box for that reason.
What It Costs
A GMRS license costs $35 to apply and $35 to renew, with no separate regulatory fee.9Federal Communications Commission. Personal Service and Amateur Application Fees Amateur licenses run the same $35. Over a 10-year term covering your whole family, GMRS works out to $3.50 a year.
Part 90 business licenses cost more. A new application carries a $105 processing fee plus a regulatory fee that depends on frequency band:
- Below 470 MHz (most common for UHF business use): $100 per license
- 470 MHz and above, or 220 MHz local: $250 per license
A new business license in the lower UHF range therefore runs about $205 in FCC fees alone, before any coordinator charges.10Federal Communications Commission. Site-Based Service Application Fees Renewals are $35 plus the applicable regulatory fee. Payments go through CORES by credit card or electronic funds transfer.
Your Radio Has to Be Certified for the Service
A license doesn’t authorize any UHF radio you happen to own. GMRS transmitters must be certified under Part 95 specifically. Every GMRS radio has to carry an FCC certification ID for GMRS, and its frequency-determining circuitry must be sealed with no external programming access.3eCFR. 47 CFR Part 95 Subpart E – General Mobile Radio Service A radio can’t be GMRS-certified if it also operates in services (like amateur) that don’t require certification.
This trips up plenty of new licensees. Cheap wide-range handhelds sold online are popular, but if they aren’t Part 95 certified, using them on GMRS channels violates FCC rules even with a valid GMRS license. The same principle applies to Part 90 business radios: equipment must be certified for the service you’re licensed under. Check the FCC ID on the device or its packaging before you buy.
License Term and Renewal
GMRS, amateur, and Part 90 business licenses all run for 10-year terms.1Federal Communications Commission. General Mobile Radio Service11eCFR. 47 CFR Part 90 – Private Land Mobile Radio Services The GMRS renewal window opens 90 days before the expiration date, and you must renew before that date passes. Miss it and the license expires; you’ll have to apply for a new one rather than renew. Set a calendar reminder well ahead of time.
Penalties for Operating Without a License
Federal law prohibits operating a radio station without proper authorization, and enforcement can include equipment seizure along with civil and criminal penalties.12Federal Communications Commission. Unauthorized Radio Operation
For individuals who aren’t broadcasters or common carriers, forfeiture penalties can reach $10,000 per violation or per day of a continuing violation, up to $75,000 for any single act.13Office of the Law Revision Counsel. 47 USC 503 – Forfeitures Because the cap is per violation, multiple days or multiple frequencies stack up quickly. Equipment seizure requires referral to a U.S. Attorney and a court warrant, and it does happen with repeat or intentional violators.
These penalties apply whether you never had a license or simply let one expire. Transmitting on an expired license carries the same legal exposure as transmitting without one. Set the renewal reminder.
