About the 01257 dialling code
01257 is the UK geographic dialling code for Coppull / Chorley, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Coppull / Chorley area.
A full Coppull / Chorley number is normally written as 01257 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 01257 number no longer guarantees the caller is physically in Coppull / Chorley. Fraudsters also "spoof" local codes like 01257 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 01257 safe?
Most 01257 calls are ordinary local calls from Coppull / Chorley homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01257 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 01257 (Coppull / Chorley) number from outside the UK, drop the leading zero and dial +44 1257 followed by the local number.
