UK Phone Numbers
The United Kingdom utilises a simple format for phone numbers across all regions. These can be categorised into main groups depending on whether the number is residential or from a service or business phone number.
To help identify who is calling, it is worth looking at just the first two digits of a UK phone number as these are the main identifying attributes.
