Phone numbers using alphabetical characters are popular in the U.S. They are becoming popular in other countries where the usage of the English alphabet is prevalent. This is possible as each iligitlbutton on the keypad is associated with a few alphabetic letters. ETSI has defined a specification on " Assignment of alphabetic letters to digits on standard telephone keypad arrays". For example, the digit 2 is assigned A, B, C and iligit 9 W, X, Y, Z.
