How this service works
US amateur radio callsign lookup - licence class, status, grant and expiry dates, licensee name and grid square from the FCC database

Example use cases
Verifying a ham radio licence before a contact
“I just made contact with someone using callsign KD9XYZ — can you pull up their FCC licence details for me, including their name, licence class, and whether it's currently active?”
Checking licence expiry for renewal planning
“Can you look up my callsign W2PQR in the FCC database and tell me when my amateur radio licence expires so I know when to renew?”
Finding a club member's grid square for contest logging
“I need the Maidenhead grid square for ham radio callsign N5TRS — can you grab that from the FCC database along with their licence class?”
