Quick facts

About the 013873 dialling code

013873 is the UK geographic dialling code for Langholm, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Langholm area.

A full Langholm number is normally written as 013873 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 013873 number no longer guarantees the caller is physically in Langholm. Fraudsters also "spoof" local codes like 013873 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 013873 from abroad

From outside the UK, dial your international access prefix, then the UK country code 44, then 13873 (the area code without its leading zero) and the local number.

Is a call from 013873 safe?

Most 013873 calls are ordinary local calls from Langholm homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 013873 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 013873 (Langholm) number from outside the UK, drop the leading zero and dial +44 13873 followed by the local number.
