070 “Personal” Numbers Explained — The Hidden Scam Costing UK Callers Up to £20 a Minute

070 number scam uk queries spike every time another batch of victims is caught by what looks like a missed call from a UK mobile. It isn’t a mobile. The 070 range is Ofcom’s “personal numbering” service, and returning a 070 missed call can legally bill you at premium rates: up to around £3.60 per minute on some lines, and far more on legacy or business tariffs. This guide explains what 070 actually is, how the scam runs in 2026, what the calls really cost, how to spot a 070 number on sight, and what to do if you have already been charged.

What 070 actually is

The 070 range is a personal numbering service, not a mobile range. It sits in Ofcom’s National Telephone Numbering Plan under “Schedule 7 personal numbering” and was designed as a single follow-me number that a subscriber could route to their landline, voicemail, mobile or office at will. The original idea, dating to the late 1990s, was a lifelong number you owned regardless of which network you were on.

The problem is visual. A UK mobile starts 07. So does 070. Most people glance at 070x xxx xxxx on their handset, see “07” and assume it’s a normal mobile call. In reality, 070 is a completely separate range with its own rate structure, and the subscriber, not the network, sets the per-minute service charge.

Genuine UK mobile numbers begin 074, 075, 077, 078 or 079. The 071, 072 and 073 ranges were reallocated to mobile after 2017 to ease number exhaustion. 076 is paging (now largely retired). 070 is personal numbering only. If a number begins 0700, 0701, 0702, 0703, 0704, 0705, 0706, 0707, 0708 or 0709, it is not a mobile call no matter how much it looks like one.

How the 070 scam works

The 070 scam is the UK form of the international “wangiri” (Japanese for “one ring and cut”) fraud. The pattern is consistent:

1. The bait call. An automated dialler places thousands of one-ring calls from rented or recently-allocated 070 numbers, usually overnight or in the early morning when victims aren’t free to answer.
2. The mistaken callback. The recipient sees a missed call from what looks like an 07 mobile and rings back, perhaps assuming a customer, a delivery driver or a recruiter has tried to reach them.
3. The bill. The service-charge meter starts the moment the call connects. The scammer keeps the caller on the line as long as possible via a hold message, fake voicemail loop, chatbot or apparent “please wait while we connect you” prompt.
4. The split. A share of the per-minute service charge flows from the originating UK carrier back to the 070 number’s owner, who in most fraud cases is operating from outside the UK.

Ofcom has been chasing this since at least the mid-2010s. The regulator’s 2017 statement on personal numbering capped retail 070 charges from consumer landlines and mobiles at no more than the cost of calling a UK mobile, effective from 1 October 2019. That cap stopped the worst of the pre-2019 horror stories. It has not stopped the underlying scam, because business lines, VoIP customers and international callers are still exposed.

What 070 calls actually cost in 2026

Since October 2019, calls from UK consumer landlines and mobiles to 070 numbers must be charged at no more than the standard rate to a UK mobile on that customer’s tariff. That sounds reassuring. It isn’t quite as protective as it reads:

• The cap applies to consumer retail rates only. Business landlines and PBX systems on non-consumer tariffs are often outside scope and may still be billed at legacy 070 rates.
• “Standard rate to mobile” is not free. For pay-as-you-go users, out-of-bundle landline customers or international callers, a 30-minute callback can still mean a real charge.
• Inclusive-minute bundles often exclude 070. Even on consumer tariffs, providers can carve 070 out of “unlimited UK calls” minutes, sending every second straight to billed call usage.

The 2019 cap is a floor, not a guarantee. A confused caller on a business PBX who is kept on hold for 25 minutes by a scammer can still rack up close to £90 of charges, which is precisely why the scam survives in 2026.

Why genuine uses of 070 are rare in 2026

Legitimate 070 traffic has collapsed since the Ofcom retail cap took effect. The commercial logic for personal numbering, charging callers a premium so the subscriber receives a share, doesn’t work once the retail price is capped at the cost of a UK mobile call. Most legitimate “follow me” services moved to 03 numbers, virtual mobile numbers or SIP-routed direct dial years ago.

What’s left on 070 is a mix of three small populations:

• A handful of long-standing professional and self-employed users who registered an 070 number in the 1990s or 2000s and never migrated.
• A few niche on-call and pager-replacement services for fields like medical locum cover.
• Wangiri-style callback fraud, which now dominates daily 070 traffic volume by a wide margin.

If you don’t recognise the caller and the number begins with 070, it is far more likely to be a scam than a legitimate UK contact. Treat it the same way you would a missed call from an unrecognised premium-rate prefix: do not return it without checking first.

How to spot a 070 number quickly

The simplest mental model: the first three digits after the leading zero tell you what you’re looking at. Train your eye on the third digit:

• 070x = personal numbering (potential scam vector). Sub-ranges currently allocated by Ofcom are 0700, 0701, 0702, 0703, 0704, 0705, 0706, 0707, 0708 and 0709.
• 071x to 075x and 077x to 079x = genuine UK mobile.
• 076x = paging (mostly legacy, largely retired but still technically allocated).

If you don’t trust your eyes at a glance, our reverse lookup tool will flag a personal numbering range explicitly. For a deeper background on the 07 family of prefixes, read our guide on UK mobile prefixes and how to tell which network owns one, and for a refresher on the wider landline space, the companion piece on UK phone area codes explained for 2026 walks through the 01, 02, 03, 08 and 09 ranges line by line.

What to do if you’ve already returned a 070 call

1. Check your phone bill within 60 days. Service-charge calls usually appear as a separate line item; flag any 070 entry, however small.
2. Contact your provider. Ask them to refund or credit the charge under their consumer-cap obligations. BT, EE, Three, Vodafone and O2 all have documented disputed-call processes.
3. Report to the PSA where applicable. The Phone-paid Services Authority regulates service-charge content; complaints help them open investigations into the receiving party.
4. Report to Action Fraud. File the incident at actionfraud.police.uk (or 101 in Scotland). Even small reports feed the national fraud picture and help intelligence teams correlate campaigns.
5. Block the number on your handset. Then add the 070 prefix to your provider’s call-screening service so future bait calls do not reach you in the first place.

How to block 070 calls on your network and phone

You can block the full 070 prefix at three layers. Combining all three is what stops repeated bait dialler campaigns from reaching you:

• Handset: iOS and Android both let you silence calls from unknown callers or specific prefixes. Our detailed walkthrough is in the guide on how to block unknown callers on iPhone, Android and business systems.
• Network: BT’s free Call Protect, Sky Talk Shield, TalkTalk CallSafe, Virgin Media’s Call Screen and the equivalent EE, Three, Vodafone and O2 mobile network protections can all auto-divert 070 traffic to voicemail or reject it outright.
• Business PBX or VoIP: Ask your provider to put a class-of-service rule on the 070 prefix so outbound dialling requires explicit override. This stops curious staff, voicemail callbacks, or an auto-dialler misconfiguration ever costing the business.

How The Business Hub’s Who Called Me tool flags 070 personal numbers

The lookup tool at The Business Hub Who Called Me reads from a clean copy of Ofcom’s National Telephone Numbering Plan, refreshed weekly. When a user looks up a number that falls inside a personal-numbering block, the result page makes the classification obvious before any charging context is read. You can browse the full 070 personal numbering range, the most common bait sub-block at /who-called-me/0700/ and other heavily-rented sub-ranges like /who-called-me/0703/ to see what’s currently in circulation. The lookup is free, unlogged and built specifically to help UK consumers and SMEs spot personal-numbering bait before they return a call.

Frequently asked questions

Is 070 a mobile number?

No. 070 numbers are personal numbering, not mobile. They were intended as lifelong “follow me” numbers that the subscriber could route to any phone they owned. They share the leading 07 with UK mobiles, which causes most of the confusion, but they sit in a completely separate range with their own rate rules. Genuine UK mobile prefixes start 074, 075, 077, 078 or 079, plus the post-2017 reallocations 071, 072 and 073.

Is 077 a mobile number?

Yes. 077 is a standard UK mobile range allocated to the major mobile networks and mobile virtual network operators. Calls to 077 numbers are charged at your tariff’s UK mobile rate or come out of your inclusive minutes. You can look up the specific operator behind a 077 block at our 077 mobile lookup to confirm the network before returning the call.

How much does it cost to call an 070 number in 2026?

From a UK consumer landline or mobile, your provider must charge no more than its standard rate for calling a UK mobile, following Ofcom’s October 2019 retail cap. In practice that means roughly 25p to 55p per minute on most tariffs, or an inclusive-minute deduction if 070 is part of your bundle. Business PBX lines, VoIP customers and international callers are often outside the cap and can pay considerably more, in some cases up to £3.60 per minute.

Can I get a refund if I’ve been charged a high 070 rate?

Often yes, especially on consumer tariffs covered by the 2019 retail cap. Contact your provider’s billing team within 60 days of the disputed bill, quote the date and time of the call, and ask for the charge to be reviewed against the consumer cap rules. If the provider refuses, escalate to the Communications Ombudsman. Where the charge originated with a scam dialler, also report it to Action Fraud and to the Phone-paid Services Authority.

Is 0700 the same kind of number as an 0700-prefixed mobile?

There is no such thing as a UK mobile starting 0700. Every 0700 number in the UK is personal numbering, not a mobile, despite the visual similarity to 07 mobile prefixes. If you see a missed call beginning 0700, treat it as a potential bait call and verify before ringing back. Look the block up at /who-called-me/0700/ to see the registered operator before returning the call.

Why hasn’t Ofcom just retired the 070 range completely?

Closing a numbering range affects every existing user, including legitimate professional subscribers and the small population of medical and on-call services that still rely on personal numbering. Ofcom has tightened the rules instead: the 2019 retail cap removed the financial incentive for most fraud, and the regulator continues to monitor the range. A full retirement remains possible but would require a multi-year transition.
