All trending monthsHow these lists are generated
The leaderboards above come from two real signal sources — both live, both auditable:
- Community reports. Approved threads in the WhoCalledLookup community that tag a specific UK number. Every thread is moderated before publication; threads that fail moderation never appear in the counts below.
- Search activity. Anonymised counts from the lookup form on the homepage and every per-number page. We store the E.164 number, an IP hash, and the timestamp — never the IP, never the user agent fingerprint, never the referrer. See the privacy policy for full detail.
Numbers that appear here are not necessarily scams. A number frequently searched or reported in our community is a strong signal that the public wants to identify it — sometimes because it’s a legitimate national contact-centre most people don’t recognise, sometimes because it’s an active scam campaign. Click any number for the per-number Ofcom range-holder data and the AI internet check, which together give you a confident answer.

FAQs
How often are these lists updated?
The leaderboards re-build every six hours from live database queries. New community threads enter the count as soon as they pass moderation; new searches enter the count immediately. Monthly trend pages aggregate calendar months, so the current month grows day by day until the next month opens.
Are the numbers on these lists definitely scams?
No — and we deliberately don't claim they are. A number appears here because either (a) someone in the community moderated and approved a thread about it, or (b) a real visitor searched for it. Both are signals of public interest, but they don't constitute proof of fraud. Use the per-number page (click any row) for the Ofcom range-holder data plus a live AI internet check before deciding how to respond to the call.
Can I add a number to one of these lists?
Yes — start a thread in the relevant <a href="https://whocalledlookup.co.uk/community" class="link">community category</a> and tag the UK number you're reporting. Once it passes moderation it counts toward the leaderboards. There is no paid promotion or pay-to-rank — every entry is here on the strength of community engagement and real search demand.
I think a number on the leaderboard is wrong. How do I get it removed?
Send an email to hello@whocalledlookup.co.uk with the number and the reason — incorrect attribution, mistaken identity, defamation concerns, or a takedown request. See our <a href="https://whocalledlookup.co.uk/editorial-policy" class="link">editorial policy</a> for our correction and takedown SLA (two working days to acknowledge, ten working days to resolve).
