About the data
Lookups come from callook.info, which mirrors the FCC's Universal Licensing System daily. Brand-new grants can take a few days to show up. Only US licenses are covered.
The grid square is geocoded from the license's mailing address, so it may not be where the station actually operates. Street addresses aren't shown here; the FCC ULS link has the full public record.
Want to know the day the FCC acts on a license? W5PRO License Alerts emails you when a call is granted, upgraded, changed or renewed, and before it expires.
Looking for a vanity call? Is this call sign available? shows when an expired or canceled call can be requested, which license classes may request it, and pending vanity applications.
