How UK phone numbers are formatted
UK numbers start with a trunk 0 followed by an area code — 020 for London, 0161 for Manchester — or 07 for mobiles. Internationally the 0 is dropped: +44 20 7946 0958.
Each landline uses the real area code of a city such as London, Manchester, Birmingham, so numbers look exactly like those your users will type.
