Is 070 a mobile number? UK 070 numbers explained (and the scam)
070 numbers look like UK mobiles but they're not. Calls cost up to 50p/min and scammers use them for ring-back fraud. Here's how to spot, block and report one.

An 070 UK number looks like a mobile number (07-something) but is not — it's a 'personal numbering' service. Calls to 070 are routed to whatever number the holder has set as their forwarding destination, and they can cost up to 50p per minute. That price difference, plus the visual similarity to a mobile, makes 070 a favourite of UK scammers in 2026.
Why people fall for it
Personal numbering services (070) are not mobile numbers. They forward calls to a number of the holder's choosing, and they can cost significantly more to call than a UK mobile. Treat any unexpected 070 call with caution.
Caller ID shows 07-something so the recipient assumes 'mobile, presumably a person'. They miss the third digit. Calls back to the 070 number cost money the recipient may not realise — and in some scams, the holder collects a revenue share on incoming calls (the 'wangiri' / one-ring scam pattern).
Genuine uses of 070
070 numbers do have legitimate uses — privacy redirects for journalists, freelance contacts who want to forward calls without exposing their personal mobile, certain old call-centre routing setups. But unsolicited calls or texts from 070 should always be treated as high-risk.
How to identify a 070 number
If a UK number's third digit is 0 (i.e. the form is 070X-XXXXXX), it's a personal-numbering service, not a mobile. Mobile numbers have the form 071X to 079X with limited sub-blocks. The full mobile-vs-personal-numbering breakdown:
| Prefix | Type | Cost to call (typical) |
|---|---|---|
| 070 | Personal numbering (call forwarding) | Up to 50p/min |
| 071–075 | Mobile (various MNOs) | Inclusive in most bundles |
| 076 | Pager (legacy) | Inclusive in most bundles |
| 077–079 | Mobile (various MNOs) | Inclusive in most bundles |
What to do if a 070 number called you
- Don't call back until you've identified it.
- Look it up on this site — Range Holder + AI internet check tells you who Ofcom assigned it to and whether others have reported it.
- If you've already called and you suspect a wangiri scam, report to Action Fraud.
- Block the number on your device and at network level (most UK carriers offer free anti-fraud filters).
Bottom line
If your phone shows an unknown UK number whose third digit is 0, treat it as a paid personal-numbering line, not a mobile. Identify it before you call back, and report any one-ring patterns to Action Fraud.

Frequently asked questions
Is 070 a mobile number?
No. UK mobile numbers start 071–079 (with limited sub-blocks). 070 is the personal-numbering range — calls are forwarded to whatever number the holder has set, and can cost up to 50p per minute.
Are 070 numbers safe?
Treat them with caution. 070 has legitimate uses (privacy forwarding for journalists, freelancers) but is heavily abused for one-ring 'wangiri' scams that profit from your callback. Always identify before dialling back.
How much does an 070 number cost to call?
Up to 50p per minute from a UK mobile, sometimes more if you call from abroad. The exact rate is set by the holder and your network's access charge.
Can I block all 070 numbers?
Some UK networks (BT Call Protect, Sky Talk Shield) let you block whole prefix ranges. Otherwise, block individual numbers on your handset and turn on the network's free spam filter.
