Who called me from 07309 742 316?

073 097 XXXXX is a UK mobile number block. UK mobiles use prefixes 071–075 and 077–079, with 076 reserved for radiopagers and 070 for personal-numbering services. A number such as 0730971234 could be active on any of the four UK mobile networks — EE, O2, Vodafone or Three — or any of the dozens of MVNOs (mobile virtual network operators) that lease capacity from them, including Tesco Mobile, Sky Mobile, giffgaff, Smarty, Lebara and Voxi.

This block — 073 097 XXXXX — was allocated by Ofcom to Hutchison 3G UK in 2017. Hutchison 3G UK either operates the numbers directly or sub-allocates them to resellers and downstream carriers, which is why a single 073 097 XXXXX prefix can be used by many different organisations. You can verify any allocation against Ofcom's National Telephone Numbering Plan, which is updated weekly.

One important caveat applies to every UK number, including this one: caller-ID spoofing means the number you see is not guaranteed to be the line actually calling. If a call from 07309 742 316 claims to be your bank, HMRC or a delivery company and asks you to act urgently, hang up and contact the organisation directly using a number you've verified yourself — for banks you can simply dial 159.

• Don't act on the call alone. If the caller claimed to be your bank, HMRC, a courier or a utility, hang up and contact the organisation on a number you find yourself — never one the caller gives you. For banks, dial 159.
• Never share security details. Full passwords, PINs and one-time passcodes are never requested by legitimate UK organisations on an outbound call.
• Don't return a missed call you don't recognise. One-ring 'wangiri' scams rely on call-backs, sometimes routed to premium-rate lines.
• Report what happened. Use the report form above to warn other UK users, and report fraud attempts to Action Fraud (or 101 in Scotland).
• If money or details were given, contact your bank immediately on 159 and report to Action Fraud.

Energy-rebate and 'green grant' scams have been linked to UK landline blocks like 073 097 XXXXX. The caller claims you're eligible for a government rebate or smart-meter grant and pressures you into giving bank details to receive it. Real government rebates apply to your bill automatically — no outbound call is needed.
