Where is the 01457 area code?
The 01457 dialling code is the UK geographic area code for Glossop. Because 01457 is a geographic (01/02) code, a number using it is tied to the Glossop dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01457 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.
Ofcom currently lists 514 number blocks under 01457, of which 145 are allocated to 91 communications providers.
Glossop phone number format
A Glossop number is made up of a 5-digit area code followed by a 5 or 6-digit local number. Written in full it looks
like 01457 XXXXXX (the Xs stand for the local digits).
Ofcom has not reserved a fictitious drama range for 01457; for
on-screen examples it recommends the unused
01632 960000–01632 960999 range.

Numbers are frequently moved (ported) between providers, and no public database reveals the person or business behind a specific number, so treat any service that claims to with suspicion.

Spotting spoofed 01457 scam calls
Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Glossop (01457) number you might trust. Remember:
- A familiar 01457 area code is not proof the caller is local or genuine — caller ID can be faked.
- Banks, HMRC and the police will never ask you to move money or share passwords or one-time codes over the phone.
- If a call feels off, hang up, wait a moment, and call the organisation back on a number from their official website or your statement.
- Report nuisance calls to the ICO and forward scam texts to 7726 (free).
