About the 029 dialling code
029 is the UK geographic dialling code for Cardiff, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Cardiff area.
A full Cardiff number is normally written as 029 XXXXX. You can dial the local part on its own from within the same area, or the full number from anywhere in the UK.
Because of UK number portability and internet calling, a 029 number no longer guarantees the caller is physically in Cardiff. Fraudsters also "spoof" local codes like 029 so an unknown call looks like a nearby business or neighbour — so treat an unexpected call on what is actually said, not on the area code alone.

Is a call from 029 safe?
Most 029 calls are ordinary local calls from Cardiff homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 029 prefix so you are more likely to answer. Never share bank details, passwords or one-time security codes with an unexpected caller, even when the number looks local — hang up and call the organisation back on a number you have verified yourself.
To call a 029 (Cardiff) number from outside the UK, drop the leading zero and dial +44 29 followed by the local number.
