Mobile (07) numbers Mixed
Numbers starting 071 to 079 (except 070) are UK mobiles. Most calls are ordinary people and businesses — but unknown mobile calls are also a very common scam channel, and 26% of people say they would answer an unrecognised UK mobile number, which fraudsters exploit.

07 is the UK mobile range (071–075, 077, 078, 079). 076 is used for pagers, and 070 is something different (a 'personal number' — see that page). A mobile number belongs to a SIM, not a place.
Who calls from 07 mobile numbers
- Individuals and sole traders
- Small businesses, tradespeople and delivery drivers
- Unfortunately, also scam call centres and spoofed-mobile fraud
How scammers use 07 mobile numbers
Fraudsters increasingly spoof UK mobile numbers because people are far more likely to answer them than an obvious international or premium number. Ofcom is introducing rules to block overseas calls that fake a UK mobile number, but until those fully land, treat an unexpected 07 call asking for money or details with caution.
Why the number on your screen isn’t proof
The single most important thing to know about any incoming call is this: the number you see can be faked. Through a technique called “spoofing”, a caller can make almost any number appear on your display — a bank’s real 0800 line, a local landline, even your own number. So the caller ID is a hint, never proof of identity.
Ofcom now requires phone networks to block many overseas calls that fake a UK landline number, and rules to block spoofed UK mobile numbers are on the way — but gaps remain. Until then, judge a call on what it asks you to do, not on the number it shows.
What to do when one of these calls comes in
- Never share security details — passwords, PINs, one-time codes or card numbers — on a call you did not start.
- If it claims to be your bank, HMRC or a company you use, hang up and call them back on a number from your card, statement or their official website.
- Don’t be rushed. Pressure to act “right now” is the most reliable scam signal.
- If money is involved, dial 159 to reach your bank safely; call 999 if you feel in danger.
Cut future nuisance calls
- Register free with the Telephone Preference Service — it becomes unlawful for UK companies to make live marketing calls to you after 28 days.
- Turn on your network’s free call protection — BT Call Protect, Sky Talk Shield, EE Scam Guard, and the O2 / Vodafone / Three apps screen known nuisance callers before your phone rings.
Where to report a bad call
- A marketing or recorded sales call → the ICO.
- A silent or abandoned call → Ofcom.
- A scam → Action Fraud on 0300 123 2040 (Police Scotland 101).
