How much does it cost to call a 01633 number?

Calls to 01633 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 01633 number — is it a scam?

Not necessarily, but be careful: scammers spoof local codes such as 01633 so a call looks like it’s from Newport 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 Newport number from abroad?

Drop the leading 0 and add +44. A number written as 01633 XXXXXX becomes +44 1633 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 01633 area code?

The 01633 dialling code is the UK geographic area code for Newport. Because 01633 is a geographic (01/02) code, a number using it is tied to the Newport dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01633 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 469 number blocks under 01633, of which 322 are allocated to 109 communications providers.

Newport phone number format

A Newport 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 01633 XXXXXX (the Xs stand for the local digits).

Who holds 01633 number ranges?

Ofcom allocates 01633 numbers to providers in blocks. These providers hold the largest allocations under 01633:

Range holder (allocated by Ofcom)	Number blocks	Example range
BT	94	`01633 20XXXX`
Virgin Media Limited	30	`01633 66XXXX`
Sky UK Limited	20	`01633 300XXX`
Gamma Telecom Holdings Limited	19	`01633 358XXX`
Vodafone Ltd (C&W)	16	`01633 350XXX`
TalkTalk Communications Limited	11	`01633 370XXX`

…and 101 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 01633 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Newport (01633) number you might trust. Remember:

A familiar 01633 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.
