What is the telephone country code for the United Kingdom?

Area code 020 is used for London landlines, which have eight digit local numbers. Mobile phones (07xxx) and special-rate services (03xx and 08xx) use their own country-wide prefixes.

To call from abroad, use the country code +44 and the full UK number minus its leading zero. For example:

• Landline 020 7946 0029 becomes +44 20 7946 0029
• Mobile 07345 123456 becomes +44 7345 123456
