Live community leaderboard
Top reported UK phone numbers
The UK numbers visitors have reported most often: moderated community threads plus caller verdicts that mark a number as scam or nuisance (verdicts marking a number as safe are not counted). Updated every six hours. Click any number for the free per-number report — Ofcom range holder, area code, caller verdicts and the original community discussion.
Reading this all-time report leaderboard
The most-reported UK number on record here is +44 7961 677001 with 4 visitor reports. The drop from rank 1 to rank 10 is 2 reports (10th place sits on 2). A long tail like this is the signature of moderation: it takes sustained, repeated first-hand reports to climb, so the top of the table moves slowly and the entries there have the most corroboration.
By number family across the 100 ranked numbers: 72% are mobiles (07), 24% are geographic landlines (01/02) and 3% are 03 non-geographic numbers. The mix matters — campaigns that lean on spoofed mobile CLIs and 084x/087x service ranges tend to dominate the report board, whereas a genuine landline rarely accumulates enough complaints to rank.
How “most reported” is measured
The leaderboard above counts visitor reports: approved community threads tagged to each UK number, and caller verdicts that mark the number as scam or nuisance. A thread is approved only after passing moderation against our editorial policy — duplicates, vendettas, defamatory claims and unmoderated PII are removed before a thread enters the count. A verdict counts once per person per number per day. Verdicts that mark a number as safe, example threads our editors wrote in April and May 2026, and verdicts left while we were testing the site are not counted.
A high rank here is a strong indicator that a number is generating real UK consumer concern — but it is not the same as a confirmed scam ruling. Some entries are known scam campaigns; others are legitimate national contact centres that happen to call out-of-the-blue and surprise recipients (HMRC genuine outbound numbers, courier redelivery desks, fraud-prevention departments at major banks). Always read the per-number page for the structured Ofcom range-holder data and the caller verdicts before deciding how to respond.

FAQs
Is everyone on this list a scammer?
No. The leaderboard ranks numbers by community-report volume — a strong indicator of public interest, not a confirmed fraud ruling. Some entries are legitimate UK contact centres whose outbound calls confuse recipients; others are active scam campaigns. Use the per-number page for the Ofcom range-holder data and caller verdicts before judging.
How often does the ranking change?
Every six hours. The page is rebuilt from a live database query, so a number that gets a new approved community thread in the last cycle will move up the ranking on the next rebuild.
What stops people gaming this list?
Every community thread is moderated before publication. Repeat-author thread floods, vendetta-style targeting and unsourced accusations are removed at moderation; the same IP/account can't artificially inflate a single number's count.
How do I get a number removed?
Send the number and reason to hello@whocalledlookup.co.uk. Editorial reviews every takedown request against our published <a href="https://whocalledlookup.co.uk/editorial-policy" class="link">editorial policy</a> — two working days to acknowledge, ten working days to resolve.
