Quick facts

About the 01431 dialling code

01431 is the UK geographic dialling code for Helmsdale, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Helmsdale area.

A full Helmsdale number is normally written as 01431 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 01431 number no longer guarantees the caller is physically in Helmsdale. Fraudsters also "spoof" local codes like 01431 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.

Calling 01431 from abroad

From outside the UK, dial your international access prefix, then the UK country code 44, then 1431 (the area code without its leading zero) and the local number.

History of the 01431 code

The code was 0431 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01431.

In the letter-dialling era the code had the mnemonic HE1 — on an old rotary dial, the letters HE (from Helmsdale) sat on the same holes as the digits 431, so subscribers literally dialled the start of the town's name.

Is a call from 01431 safe?

Most 01431 calls are ordinary local calls from Helmsdale homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01431 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 01431 (Helmsdale) number from outside the UK, drop the leading zero and dial +44 1431 followed by the local number.
