If a 07873 number called you
Most verdicts on these numbers say scam, so treat unexpected calls as possible scams.
- 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
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 07873 number?
07873 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 07873 numbers is O2 (Telefonica UK Limited), one of 2 providers on this block. 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.
