Where this data comes from

The FCC publishes its amateur license and application tables as bulk files: a complete set every Sunday, and each day's changes the next morning. A job loads them into SANDARC's copy nightly, so every query here is current to the previous business day. Records from before amateur licensing moved into ULS in August 1999 are not in those files.

Looking for a single current record? The callsign lookup also shows the live FCC record through ExamTools, and SANDARC files renewals for free.
