What to do if one of these numbers calls you

A number appearing here means other people have reported unwanted calls from it — but treat each entry as a caution, not proof: numbers can be spoofed, reassigned, or reported in error. If one of these numbers calls you, don't share bank details, passwords or one-time security codes, and if in doubt hang up and call the organisation back on a number you've verified yourself.

Block or report a reported number

You can block a reported number directly from your recent-calls list on iPhone or Android, and forward scam texts free to 7726.
Scam or fraud calls should be reported to Action Fraud (0300 123 2040) or Police Scotland (101); persistent marketing calls to the ICO / TPS.

Full step-by-step instructions for every phone, network-level blocking and all UK reporting routes are in our guide: How to block and report unwanted calls in the UK.

How the ranking is built

Every number on this page is ranked from our own moderated community reports. When a visitor looks up a number on our UK Number Checker they can report the type of call they received — scam, spam, telemarketing, silent / robocall or unknown. We approve genuine reports, then rank each number by how many it has received, breaking ties by how often the number is looked up. Numbers reported only as legitimate are excluded, and the list rebuilds nightly. Mobile numbers are part-masked for privacy.
