Quick facts

About the 017687 dialling code

017687 is the UK geographic dialling code for Keswick, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Keswick area.

A full Keswick number is normally written as 017687 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 017687 number no longer guarantees the caller is physically in Keswick. Fraudsters also "spoof" local codes like 017687 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 017687 safe?

Most 017687 calls are ordinary local calls from Keswick homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 017687 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 017687 (Keswick) number from outside the UK, drop the leading zero and dial +44 17687 followed by the local number.
