If a 029 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.

    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.

029 history and number format

Number format: Numbers on 029 use Ofcom's 2+8 format: the 3-digit code (including the leading 0) followed by a 8-digit local number — written like 029 2345 6789.

Before 2000: 029 dates from the Big Number Change on 22 April 2000. Cardiff moved from 01222 to 029 with 8-digit local numbers.

Local dialling: Traditionally not from another 029 landline, but it now depends on your provider: Ofcom stopped requiring providers to offer local (code-free) dialling on 11 March 2022. Dialling 029 first always works, and mobiles always need it.

Allocation record: the oldest number block still visible on 029 was allocated on 26 May 1999, and the most recent on 10 July 2026. 3 blocks were allocated in the last 12 months — newly-activated ranges with no call history, which is worth knowing when an unfamiliar 029 number rings (see the weekly numbering changelog for every new allocation.)
