What are 0306 numbers?
Numbers starting 0306 are UK uk-wide non-geographic
numbers in Ofcom’s 03 numbers
range. They are not tied to any town or city. Ofcom currently lists
1,000 number blocks under 0306, of which
7 are allocated to
5 providers.
0306 999 0000 is in the range Ofcom reserves for TV and radio dramas, so it can never connect to a real subscriber — that’s why we use it as the live example above.
Who uses 0306 numbers?
Public bodies, charities and national businesses that want one number for the whole UK without tying it to a town.
Who holds 0306 number ranges?
| Range holder (allocated by Ofcom) | Number blocks | Example range |
|---|---|---|
| Resilient Limited | 3 | 0306 790 XXXX |
| BT | 1 | 0306 770 XXXX |
| Fuse 2 Communications Ltd | 1 | 0306 800 XXXX |
| Nodemax Limited | 1 | 0306 565 XXXX |
| TelecomIQ Limited | 1 | 0306 464 XXXX |
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.
Scam & cost warnings
0306 numbers are low-risk for callers because Ofcom caps their cost at the 01/02 rate — but scammers still use and spoof them precisely because they look official. An 0306 caller ID is not proof you’re talking to a government body or bank.
