All international numbers MUST be prefixed with "+" followed by the country code and MUST be a minimum of 12 characters in length. Any leading zero in the area code MUST be omitted except where the area code has been incorporated into the subscriber's number and a leading zero has been retained (the only known instance of this is with Italian landlines, international prefix +39).

Text SHOULD NOT be included within the telephone number (apart from when used as part of the extension number convention).
Visual separators (e.g. hyphens, dots and brackets) MUST NOT be included.
