Scam and nuisance call checker for UK numbers
Over 129 million fraudulent robocalls were received by UK subscribers in 2024, and half of all mobile users received a suspicious text or call within any given three-month period. Despite Ofcom guidance requiring operators to block international calls spoofing UK numbers, and BT alone blocking up to one million calls per day, scammers constantly find new ways through. Checknumber collects reports from users who received the same call, categorises each number by caller type and displays activity statistics so you can spot fraud before it reaches you.
Real user reports from the UK and around the world
Every number page on Checknumber is built from reports submitted by people who received that exact call across all 24 countries where the service runs. Each contribution from UK users and those abroad makes the database more accurate and the community better protected.
