Quick facts

About the 01289 dialling code

01289 is the UK geographic dialling code for Berwick-upon-Tweed, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Berwick-upon-Tweed area.

A full Berwick-upon-Tweed number is normally written as 01289 XXXXXX. 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 01289 number no longer guarantees the caller is physically in Berwick-upon-Tweed. Fraudsters also "spoof" local codes like 01289 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 01289 safe?

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.
