How we get this data
FCC ULS data as of Sep 27, 2026Everything FreqKeeper shows about a license comes from one place: the FCC's public weekly database download for private land mobile (Part 90) licenses, l_LMpriv.zip, published at data.fcc.gov.
- The FCC builds the file every weekend. Every Monday our loader downloads it, checks that each data file has exactly the number of lines the FCC's own counts file says, and rejects the load if anything looks truncated.
- We read two record types: license headers (status, radio service, grant and expiration dates) and entities (licensee and contact names, emails, FRN).
- We compare the new file with last week's and record what changed: status, expiration, licensee name, emails, FRN, and new licenses.
- Your board, reminders and weekly digest are computed from that comparison. Every screen shows the as-of date of the file behind it.
What we don't do
- We never scrape FCC web pages or any third-party site.
- We don't log in to ULS or CORES, and we don't file anything with the FCC.
- We don't use frequency or location records yet, and we don't cover other radio services (Part 22/101, amateur, GMRS).
Because the source is weekly, a renewal filed today shows up after the FCC processes it and publishes the next file. Always confirm important dates in the FCC's license search.
