Common questions about UK phone numbers
How do I find out who called me from a UK number?
Type the number into our free UK Phone Number Checker. It runs a longest-prefix lookup against live Ofcom range-holder data and shows you which UK communications provider Ofcom originally allocated that number block to, plus the number type, geographic area (for 01/02 landlines), call-cost guidance and a risk flag for scam-prone ranges.
Is there a free UK reverse phone lookup?
Yes — our checker at /check-uk-phone-number is completely free, no signup, no ads. It works for any UK number (mobile, landline, freephone, premium, personal-numbering) and returns Ofcom range-holder data instantly.
Which UK prefix is most often a scam?
070 (personal-numbering) is the most scam-prone UK prefix — calls are expensive (up to £1+/min) and the range is heavily abused for callback fraud. Specific 07-mobile prefixes like 07441 and 07379 have also been reported repeatedly in 2025-26 for HMRC, Royal Mail and bank impersonation scams.
How can I block UK spam calls?
For individual numbers, use your phone's block function (iPhone: Phone app → Recents → (i) → Block; Android: Phone app → Recents → long-press → Block). For ongoing protection, enable iPhone's "Silence Unknown Callers" or Android's "Filter spam calls". For sales-call reduction, register with the Telephone Preference Service (TPS) at tpsonline.org.uk.
What is an Ofcom "range holder"?
The range holder is the UK communications provider (BT, Gamma, Vodafone, Sky, EE, O2, Three, Virtual1 and others) that Ofcom originally allocated a block of numbers to. It is the most reliable public-data answer to "whose number is this?" Numbers can be ported to other providers after allocation, but the range holder remains the standard industry reference.
