How 0300 & 0303 Numbers Work

0303 & 0300 numbers work in exactly the same way as other non-geographic numbers (e.g. 0845 numbers), except they are cheaper to call, even from mobiles. 030 numbers are the same as 033 numbers, but are exclusively reserved for non-profit organisations.

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 a customer dials your 030 number the call is automatically (and instantly) routed to your existing landline number or mobile number. You can change this target number at anytime online using My Windsor, or via the phone with Instant Call Rerouting. 030 numbers can be set-up quickly and you don't need to install and maintain any software or hardware.

You can also choose to use an 03 number as a fax to email line.
