The Structure and Format of UK Phone Numbers
UK phone numbers follow a defined numbering plan car owner database regulated by Ofcom, the UK’s communications regulator. The UK dialing code is +44, and the number typically consists of an area code and a subscriber number.
Geographic Numbers: These start with a ‘01’ or ‘02’ prefix, for example, 020 7946 0018 (London).
Non-Geographic Numbers: Starting with ‘03’, ‘08’, or ‘09’, often used for business services, toll-free or premium rate calls.
Mobile Numbers: Typically start with ‘07’, such as 07123 456789.
Special Numbers: Emergency services (e.g., 999) and personal numbering (e.g., 070) also have designated formats.
UK phone numbers vary in length, usually between 10 and 11 digits after the country code. Formatting often includes spaces for readability, but the international standard E.164 format removes spaces and uses a plus sign (e.g., +447123456789).
