03 numbers are 'virtual' and sit on an existing landline or mobile, in exactly the same way as other non-geographic numbers (e.g. 0800). 03 numbers differ from other ranges as they are cheap to call - even from mobiles. This is really important for businesses receiving a lot of calls from customers on mobiles, as other non-geographic numbers are expensive to call from mobile phones. Even 0800 freephone numbers, which currently cost around 25p per minute to call from a mobile which unsurprisingly, puts a lot of people off.

We like to think of 0330 numbers and 0333 numbers as being 'fair for all', meeting the ever-growing public demand for a recognisable phone number range which is cheap to call from a both a landline and mobile. Calls to both 0330 numbers and 0333 numbers cost the same as a normal landline number (even from a mobile), or are completely free if the caller has free minutes. This is why a lot of savvy businesses are turning to 03 numbers and you might have even noticed some of the companies that use 03 numbers: BBC, EBay, Lloyds TSB, Transport for London and countless SME's.

Another great benefit of 03 numbers is you can actually choose your telephone number! We have thousands of highly memorable numbers to choose from, helping customers to easily remember you and standout from the competition. One of our customers that specialises in domestic cleaning uses our highly memorable 0330 999 0000 number and you can also use digits related to your industry. Do you offer a round the clock service? If you do, imagine in your number included '247'. Are you an advisory service? Then include '121' in your number.

When a customer dials your 0330 or 0333 number the call is instantly routed to your existing landline or mobile number (referred to as your 'target'). Conveniently, you can change this target number at any time online using My Windsor, or via the phone with our Instant Call Rerouting service. 0333 and 0300 numbers can be set up quickly and you don't need to install and maintain any software or hardware.

Diverting To Mobile

Add 250 minutes of talk time to your mobile routing facility for £10 per month. This works out at just 4p per minute instead of the Pay as you go rate of 9.95p. Another benefit of this popular package is that any extra minutes used over the 250 limit are charged at just 6p per minute. You can purchase Divert To Mobile 250 as a customer via My Windsor, our online portal. View Mobile Divert Costs.

Fax To Email

You can also choose to use a 03 number as a Fax to Email line, where faxes are received via your email. This is a great alternative to having a fax machine, which is traditionally expensive what with the on-going maintenance and material costs. What's more, you don't need a physical landline if you choose Fax to Email, again, saving you a lot money.
