About WhoCalledLookup

WhoCalledLookup answers one question: who just called me? The US edition combines four data layers, each with a different strength:

• NANPA numbering records — the official North American Numbering Plan data tells us which city, state and time zone every area code serves. We refresh it weekly from NANPA's public reports.
• Carrier prefix assignments — each 6-digit prefix (area code + exchange) is assigned to a carrier and rate center. This tells you whether a number is wireless, landline or VoIP, and which company the prefix belongs to. Numbers can be ported between carriers, so this shows the assigned carrier, not necessarily the current one.
• FCC Consumer Complaint Data — the FCC publishes every unwanted-call complaint filed by US consumers as open public data, including the caller's number. We import it nightly and aggregate complaint counts per number. This is public record, republished with attribution.
• Community reports — first-hand accounts from people who answered the call. Every report is moderated before publication; we remove personal information, profanity and unverifiable accusations against named individuals.

What we are not

WhoCalledLookup is not a consumer reporting agency under the Fair Credit Reporting Act (FCRA). Our data must not be used to evaluate anyone for employment, credit, insurance, housing or any other FCRA-regulated purpose. We are a number-reputation service — we publish information about phone numbers, not people, and we never sell personal data.

Who runs this

WhoCalledLookup is built and operated by OmegaIT, the team behind the UK edition at whocalledlookup.co.uk, led by Andrew Pickett. The site is free to use and supported by advertising.
