Looking for a phone number that isn’t tied to a single town, but sounds professional right across the UK? Then a 0333 number is exactly what you need! It’s a national business number you can use the same day, with no new hardware.
With a 0333 number you show that you operate across the whole UK, not just in one town. And if you move to another city later, you simply keep the same number, so you can keep using it on your website, invoices and email signature.
For your callers, dialling you is easy. A 0333 number is charged at the standard landline rate and is included in mobile minute bundles, so for most people calling you is effectively free — and unlike 0845 or 0870, it’s never surcharged.
An incoming call on your number we forward to your existing phone, landline or mobile, or to several phones so you form a team with colleagues. You adjust where calls land in real time, so they always reach the right phone at the right moment. That way you never miss a call.
You choose a number that suits you, for example an easy-to-remember combination. Your number is activated the same working day, so you can be reached straight away.
Because such a number runs in the cloud, you get smart features included. Think of a menu, call queues, call recording and professional welcome messages you create yourself with our text-to-speech assistant.
A 0333 number is an official UK business number issued under Ofcom rules. Show it clearly on your website and in your communication, so customers who look up your number recognise your business right away and pick up.
Your new number is usually active within one working day. Request your number and we’ll get to work for you.

FAQ 0333 numbers
Common questions about UK 0333 national numbers.
Not technically “free” like 0800, but effectively free for most people. Calls to 0333 numbers are charged at the same rate as standard landlines (01 and 02) and must be included in inclusive minute bundles on mobile and landline packages. Callers without a bundle pay the standard geographic rate set by their own network, never a premium rate.
0333 is an Ofcom-regulated, standard UK business range used by banks, charities and government services precisely because it reads as legitimate. A properly registered 0333 number carries no less trust than a landline number, and CallFactory activates yours against your own business account so the calls you make and receive are tied to your company. Some scam callers do spoof numbers across every UK range, including 0333, geographic and mobile alike, but that risk comes from the caller’s conduct, not from the number type itself.
There is no technical or cost difference. Both 0333 and 0330 are “UK Wide” numbers with the same regulations. 0333 is often considered slightly more memorable.
