How much does it cost to call a 01740 number?

Calls to 01740 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 01740 number — is it a scam?

Not necessarily, but be careful: scammers spoof local codes such as 01740 so a call looks like it’s from Sedgefield 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 Sedgefield number from abroad?

Drop the leading 0 and add +44. A number written as 01740 XXXXXX becomes +44 1740 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 01740 area code?

The 01740 dialling code is the UK geographic area code for Sedgefield. Because 01740 is a geographic (01/02) code, a number using it is tied to the Sedgefield dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01740 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 451 number blocks under 01740, of which 130 are allocated to 90 communications providers.

Who holds 01740 number ranges?

Ofcom allocates 01740 numbers to providers in blocks. These providers hold the largest allocations under 01740:

Range holder (allocated by Ofcom)	Number blocks	Example range
Virgin Media Limited	12	`01740 600XXX`
GCI Network Solutions Limited	11	`01740 67XXXX`

…and 82 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 01740 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Sedgefield (01740) number you might trust. Remember:

A familiar 01740 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.
