How much does it cost to call a 01780 number?

Calls to 01780 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 01780 number — is it a scam?

Not necessarily, but be careful: scammers spoof local codes such as 01780 so a call looks like it’s from Stamford 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 Stamford number from abroad?

Drop the leading 0 and add +44. A number written as 01780 XXXXXX becomes +44 1780 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 01780 area code?

The 01780 dialling code is the UK geographic area code for Stamford. Because 01780 is a geographic (01/02) code, a number using it is tied to the Stamford dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01780 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 424 number blocks under 01780, of which 144 are allocated to 95 communications providers.

Stamford phone number format

A Stamford 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 01780 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01780; for on-screen examples it recommends the unused 01632 960000–01632 960999 range.

Who holds 01780 number ranges?

Ofcom allocates 01780 numbers to providers in blocks. These providers hold the largest allocations under 01780:

Range holder (allocated by Ofcom)	Number blocks	Example range
BT	13	`01780 41XXXX`
Barritel Limited	9	`01780 280XXX`
Gamma Telecom Holdings Limited	7	`01780 430XXX`
Vodafone Ltd (C&W)	7	`01780 42XXXX`
Magrathea Telecommunications Limited	6	`01780 400XXX`
Lumen Technologies UK Limited	4	`01780 790XXX`

…and 87 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 01780 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Stamford (01780) number you might trust. Remember:

A familiar 01780 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.
