0333 numbers are examples of a non-geographic phone numbers. These are numbers that are not linked to any locality within the UK. They were introduced in 2007 as an alternative to the traditional landlines that were usually assigned geographically through the use of a system of location-specific area codes. All 0333 numbers are landline numbers. However, unlike the ‘01’ or ‘02’ landline numbers, you cannot identify the area 0333 numbers are associated with.
