How do 0303 & 0333 Numbers Work?

0303 & 0300 numbers work in exactly the same way as other non geographic numbers (e.g. 0845 and 0870 numbers), except they are cheaper to call, even from mobiles.

03 phone numbers meet the strong and growing public demand to have a recognisable phone number, which both identifies the type of organisation being called and offers a clearly priced call.
When somebody phones your new 03 number the call is automatically and instantly redirected to a telephone number of your choice. This is usually your existing landline number and can even be a mobile* number.
Using your inclusive call management package you can change this ‘destination’ number as often as you wish, for free. So even if you move premises or you simply want your inbound calls redirected to another person for a short period of time, your 0303 or 0300 numbers stay the same.
