For data corrections (a code, prefix or locality that disagrees with current NANPA records), source questions, or anything else about the site, write to [email protected] — we read everything.
If you spot outdated numbering data, please include the page URL and, if you have it, a link to the current NANPA record; the fix then makes it into the next regeneration cycle.
We do not run a lookup service for individual numbers and cannot tell you who called you — see About for why. For scam calls, the right channels are ReportFraud.ftc.gov and the FCC Consumer Complaint Center.
