Frequently Asked Questions

What is an FCC call sign?

An FCC call sign is a unique identifier assigned to every licensed radio station in the United States. Depending on the service, this could be an amateur radio operator, a GMRS user, a ship or aircraft, a business running a land mobile radio system, or many other types of licensees. Call signs allow the FCC to track and manage the use of the radio spectrum.

What services are in the ULS database?

The FCC's Universal Licensing System covers dozens of radio services including Amateur Radio (ham), GMRS (General Mobile Radio Service), Ship/Maritime, Aircraft, Land Mobile (private and commercial), Microwave, Paging, Cellular, and more. CallSignLookup indexes all major service categories from the publicly available ULS bulk data files.

What is GMRS?

GMRS (General Mobile Radio Service) is an FCC-licensed radio service for short-distance two-way communications. A single GMRS license covers the licensee and their immediate family. GMRS radios operate on UHF frequencies and are commonly used for outdoor recreation, emergency preparedness, and family communications. A license is valid for 10 years.

Where does this data come from?

All data comes from the FCC Universal Licensing System (ULS) bulk data files, which are published as free public downloads and updated weekly. Records are joined across multiple FCC data files (HD, EN, AM, SH) to build a complete licensee profile.
