A number in international format consists of a plus sign, then a country code followed by the mobile phone number (without the first ‘0′ of the number):
‘+’, country code, network prefix without the leading “0″, number, no spaces, only numerals.
- For example, the UK number 07777123456 becomes +447777123456. The number 44 is the country code for the UK.
- For example, the US number (248) 123-7654 becomes +12481237654. The number 1 is the country code for the US.
