Why 03 Numbers Are Regulated to Landline Rates

03 numbers exist precisely so businesses and organisations can have a national, non-geographic identity without charging callers a premium.

Under the rules governing the 03 range, providers must charge calls at the same rate as calls to 01 and 02 geographic numbers, and the numbers must be included in any call package that includes 01/02 calls. This is why an 03 number is the customer-friendly, transparent choice: there is no hidden service charge and no confusion about what a call will cost.

For you, that regulatory backing is a selling point — you can advertise your 03 number knowing customers won't be surprised by their bill, which is exactly why public bodies, charities and reputable businesses have moved to 03.
