About the 01457 dialling code
01457 is the UK geographic dialling code for Glossop, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Glossop area.
A full Glossop number is normally written as 01457 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 01457 number no longer guarantees the caller is physically in Glossop. Fraudsters also "spoof" local codes like 01457 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.

History of the 01457 code
The code was 0457 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01457.
In the letter-dialling era the code had the mnemonic GL7 — on an old rotary dial, the letters GL (from Glossop) sat on the same holes as the digits 457, so subscribers literally dialled the start of the town's name.

Is a call from 01457 safe?
Most 01457 calls are ordinary local calls from Glossop homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01457 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 01457 (Glossop) number from outside the UK, drop the leading zero and dial +44 1457 followed by the local number.
