How to Find All Licenses Associated With a Person's FRN

Every individual and organization that does business with the FCC has a unique FCC Registration Number (FRN). Because the FRN is the linking identifier across all FCC systems, you can use it to find every radio license — across all radio services — associated with a single person or entity. This is more powerful than searching by call sign, which only returns one license at a time.

Why One Person Might Hold Multiple Licenses

It is common for active radio operators to hold licenses in more than one service:

• An amateur radio operator who also holds a GMRS license
• A maritime pilot with both a ship station license and a Restricted Operator Permit
• A business owner with amateur, GMRS, and land mobile licenses
• A club trustee who holds both their personal amateur license and the club license under their FRN

How to Search by FRN in the ULS

In the FCC ULS at wireless.fcc.gov, navigate to License Search and select the FRN field. Enter the ten-digit FRN and submit. The results page shows all active, expired, and cancelled licenses associated with that FRN across all radio services.

Finding an FRN Without Already Knowing It

If you do not know a person's FRN but know their call sign, look up the call sign first. The license record will display the associated FRN. From there, you can search by FRN to see all other licenses tied to that number.

Practical Uses

• Verifying that a person holds all the licenses they claim
• Reviewing your own complete licensing history
• Researching a business's complete radio licensing portfolio
• Checking whether a club trustee has a current personal amateur license (required for the club license to remain valid)

The FRN-based search is one of the most powerful tools in the FCC ULS. Combined with the name-based entity search, it gives a complete picture of any licensee's FCC history.
