Callsign Lookup

Any callsign in the world: its country, zones, local time, sunrise and sunset, and your beam heading. For US and Canadian calls, also the name, license class and grid square. Free, with no sign-in.

Where the Data Comes From

Public license records from the FCC (US) and ISED (Canada), served by the free HamDB and Callook services. New licenses can take a few days to appear.
