Quick facts

About the 015242 dialling code

015242 is the UK geographic dialling code for Kirkby Lonsdale, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Kirkby Lonsdale area.

A full Kirkby Lonsdale number is normally written as 015242 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 015242 number no longer guarantees the caller is physically in Kirkby Lonsdale. Fraudsters also "spoof" local codes like 015242 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 015242 from abroad

From outside the UK, dial your international access prefix, then the UK country code 44, then 15242 (the area code without its leading zero) and the local number.

Is a call from 015242 safe?

Most 015242 calls are ordinary local calls from Kirkby Lonsdale homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 015242 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 015242 (Kirkby Lonsdale) number from outside the UK, drop the leading zero and dial +44 15242 followed by the local number.
