Check a number freeThese guides answer one question: who called me from this kind of number? Start with who called me in the UK — that page has the checker on it — then the format guides for a +44 7 mobile and for international numbers (any + country code). Ireland has its own page because those calls are so often genuine: who called me from a +353 number.
Country-code guides cover the numbers UK phones see most often: +1 USA and Canada, +33 France, +49 Germany, +34 Spain, +39 Italy, +91 India, +92 Pakistan and +234 Nigeria. Each one explains the format, who genuinely calls, the scam pattern for that code, and what ringing back costs.
UK number types are covered separately — 03 numbers, 0800, 084 / 087, 09 premium-rate and 070 — alongside practical guides on checking if a number is a scam, blocking unwanted calls and reporting a scam number.
