- E.123
ITU-T Recommendation E.123, or the Notation for national and international telephone numbers Recommendation E.123 defines a standard way to writetelephone number s,e-mail address es, andweb address es. It recommends the following formats (when dialling the area code is optional for local calling):Telephone number, national notation: (042) 123 4567 Telephone number, international notation: +31 42 1234567 E-mail address: name@example.com Internet address / URL: www.example.com
E.123 recommends that only spaces be used to visually separate groups of numbers, "...unless an agreed upon explicit symbol (e.g. hyphen) is necessary for procedural purposes..." in national notation. Only spaces should be used to visually separate groups of numbers in international notation. In national notation, parentheses are used to indicate digits that are sometimes not dialled. Parentheses should not be used in the international notation. A slash (/) may be used to indicate alternate numbers.
In case of emergency
A standardized language-independent way to identify a
next-of-kin (or other emergency contact) in a mobile handset’s directory, in case of an emergency, has in May2008 been adopted as a new clause in Recommendation E.123.It proposes to store emergency contact numbers prefixed with
arabic numerals in the form “0nxxxx”; “n” is a digit from 1 through 9 and “xxxx” is any meaningful descriptive character string in any language or script (e.g. “Anna” or “Spouse”).In the handset's directory this would be displayed as "01Anna" or "01Spouse" enabling easy identification by the emergency services. The handset’s directory entry (in the “contact number” field) would contain the actual number of the person to call in case of emergency.

This scheme is a language-independent version of the ICE scheme that became popular in certain parts of the world from
2005 onwards. [ [http://new.cambridge-news.co.uk/cn_news_newmarket/displayarticle.asp?id=198611 Bob's idea has global impact (Cambridge Evening News)] ]References
