Quick facts

About the 028 dialling code

028 is the UK geographic dialling code for Northern Ireland, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Northern Ireland area.

A full Northern Ireland number is normally written as 028 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 028 number no longer guarantees the caller is physically in Northern Ireland. Fraudsters also "spoof" local codes like 028 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 028 safe?

Most 028 calls are ordinary local calls from Northern Ireland homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 028 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 028 (Northern Ireland) number from outside the UK, drop the leading zero and dial +44 28 followed by the local number.
