How much does it cost to call a 01737 number?

Calls to 01737 numbers are standard geographic landline calls, charged at your provider’s normal UK landline rate and usually included in inclusive minutes — the same as calling an 03 number.

I had a missed call from a 01737 number — is it a scam?

Not necessarily, but be careful: scammers spoof local codes such as 01737 so a call looks like it’s from Redhill and you’re more likely to answer. If in doubt, hang up and call the organisation back on a number you find independently.

How do I dial a Redhill number from abroad?

Drop the leading 0 and add +44. A number written as 01737 XXXXXX becomes +44 1737 XXXXXX when dialled internationally.

Can this tool tell me who owns the number?

No. It shows the area of the dialling code and the provider Ofcom allocated the number range to — not the individual or business holding a specific number, which may also have been ported to another network.

Where is the 01737 area code?

The 01737 dialling code is the UK geographic area code for Redhill. Because 01737 is a geographic (01/02) code, a number using it is tied to the Redhill dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01737 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 433 number blocks under 01737, of which 212 are allocated to 103 communications providers.

Redhill phone number format

A Redhill 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 01737 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01737; for on-screen examples it recommends the unused 01632 960000–01632 960999 range.

Who holds 01737 number ranges?

Ofcom allocates 01737 numbers to providers in blocks. These providers hold the largest allocations under 01737:

Range holder (allocated by Ofcom)	Number blocks	Example range
BT	24	`01737 19XXXX`
Virgin Media Limited	18	`01737 21XXXX`
Sky UK Limited	12	`01737 200XXX`
Vodafone Ltd (C&W)	11	`01737 32XXXX`
Gamma Telecom Holdings Limited	9	`01737 30XXXX`
GCI Network Solutions Limited	8	`01737 39XXXX`

…and 95 more providers hold smaller allocations in this range.

Ofcom’s data shows the provider each number range was originally allocated to — not who holds an individual number today. 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 01737 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Redhill (01737) number you might trust. Remember:

A familiar 01737 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.
