What Are 03 Numbers?

03 numbers are a non-geographic alternative to 0800 and 01/02 numbers, allowing businesses and organisations to establish a national presence without being tied to a location. Unlike 0800 numbers, they are charged at standard local rates from mobiles and landlines, making them affordable for both businesses and callers.
