Question 67 of 490
What is the maximum length of any numeric geographic area address in ITU recommendation E.164?
E.164 defines a general format for international telephone numbers.
Plan-conforming numbers are limited to a maximum of 15 digits.
The presentation of numbers is usually prefixed with the character + (plus sign), indicating that the number includes the international country calling code (country code), and must typically be prefixed when dialing with the appropriate international call prefix, which is a trunk code to reach an international circuit from within the country of call origination.
