The most-reported UK scam numbers

The single most-reported UK number right now is +44 7724 561379, tied to 2 approved community reports. Across the 479 numbers we currently track, the community has logged 482 reports in total. Reports in September 2026 are with no comparable figure for the previous month.
Broken down by number family, 78% are mobiles (07), 19% are geographic landlines (01/02), 1% are 03 non-geographic numbers and 1% are 0800/084x/087x service numbers. That mix matters: spoofed mobile (07) CLIs and 084x/087x service ranges typically dominate report volumes, while a genuine geographic landline rarely attracts enough complaints to climb the table.
Top reported UK numbers
The 100 UK numbers with the most approved community reports, ranked by report volume. Each row links to a free per-number page with the Ofcom range holder, area code and the original discussion threads.
The table has a steep head: the gap between the number at rank 1 and the one at rank 10 is 1 reports (10th place currently sits on 1 report). That long tail is the signature of moderation — it takes sustained, corroborated, first-hand reports to climb, so the worst-offending numbers at the top are also the most-evidenced.
How this report is compiled
Every figure above is derived from a single live source: approved community threads tagged to a specific UK number. A thread only enters the count after it passes human moderation against our published methodology — duplicate posts, vendetta-style targeting, defamatory claims and unmoderated personal data are removed before a report is counted. Number families and area codes are classified against the official Ofcom Numbering Data; the full list of primary references is set out on our sources page.
A high position in this report is a strong signal that a number is generating real UK consumer concern — but it is not a confirmed ruling of fraud. Some entries are active scam campaigns; others are legitimate national contact centres (banks, couriers, government departments) whose unexpected outbound calls surprise recipients. We deliberately rank by reporting volume and let readers judge each number on its per-number page. The dataset is rebuilt every six hours, so a number that attracts new reports moves up the table on the next refresh.
The report is intentionally conservative about what it claims. It measures how many people felt strongly enough to file a moderated report about a number — a proxy for nuisance and scam pressure, not a regulator’s verdict. Reporting volume is also shaped by awareness: a campaign that targets a large, vocal demographic will generate more reports than an equally harmful campaign aimed at a smaller group, so the ranking should be read as a guide to where public concern is concentrated rather than a complete census of UK scam activity. We publish the methodology in full so the limitations are as transparent as the figures themselves.
