If a 07307 number called you
No clear pattern in reports for these numbers yet. If a call worried you:
- 1
Call back on a number you trust
If a caller says they're your bank, HMRC, a courier or a council, hang up and ring the organisation on the number from its website or your statement, never the number that called you. Caller ID can be faked.
- 2
Forward it to 7726
On a mobile, copy the caller's number from your recent calls and text it to 7726 (it spells SPAM). Scam texts can be forwarded to 7726 as they are. It's free, and your network uses the reports to investigate and block numbers.
- 3
Stop sales calls
Register your landline and mobile free with the Telephone Preference Service (0345 070 0707). Legitimate UK marketers must check it; calls should drop within 28 days. It won't stop scammers.
- 4
If you lost money or shared details
Call your bank on the number on your card (or 159 to reach most UK banks safely), then report it to Report Fraud online or on 0300 123 2040. Report Fraud replaced Action Fraud on 4 December 2025 for England, Wales and Northern Ireland; in Scotland call Police Scotland on 101.
Who owns a 07307 number?
The 07307 block sits within Ofcom's 0730 mobile range — one of the newer tranches opened as the UK's earlier 077 and 078 ranges filled up. Numbers here are handed to the main networks and the MVNOs that piggyback on them, so a 07307 call could originate from almost any provider's SIM. That breadth is exactly why 07307 turns up in 'who called me' searches whenever an unsaved number rings.
07307 is not an area code: it is a slice of the national 07 mobile range that Ofcom hands to providers in blocks. The largest holder of 07307 numbers is Three (Hutchison 3G UK Ltd). A number can be ported to another network while keeping its digits, so the holder is the original provider rather than necessarily today’s. The person behind a number isn’t public: no legitimate free service can name a stranger from their mobile number. See UK mobile networks by prefix for how blocks are shared out.
