If a 0333 number called you

No clear pattern in reports for these numbers yet. If a call worried you:

  1. 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. 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. 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. 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.
