How much does it cost to call a 01420 number?

Calls to 01420 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 01420 number — is it a scam?

Not necessarily, but be careful: scammers spoof local codes such as 01420 so a call looks like it’s from Alton 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 Alton number from abroad?

Drop the leading 0 and add +44. A number written as 01420 XXXXXX becomes +44 1420 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 01420 area code?

The 01420 dialling code is the UK geographic area code for Alton. Because 01420 is a geographic (01/02) code, a number using it is tied to the Alton dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01420 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 397 number blocks under 01420, of which 142 are allocated to 96 communications providers.

Alton phone number format

A Alton 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 01420 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01420; for on-screen examples it recommends the unused 01632 960000–01632 960999 range.

Who holds 01420 number ranges?

Ofcom allocates 01420 numbers to providers in blocks. These providers hold the largest allocations under 01420:

Range holder (allocated by Ofcom)	Number blocks	Example range
BT	24	`01420 22XXXX`
Vodafone Ltd (C&W)	9	`01420 391XXX`
Sky UK Limited	5	`01420 257XXX`
TalkTalk Communications Limited	4	`01420 352XXX`
GCI Network Solutions Limited	3	`01420 21XXXX`
AQL Wholesale Ltd	2	`01420 375XXX`

Digital Space Group Limited	2	`01420 33XXXX`

…and 88 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 01420 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Alton (01420) number you might trust. Remember:

A familiar 01420 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.
