Scope

This European Telecommunications Standard (ETS) defines the assignment of alphabetic letters to digits on standard telephone keypad arrays. The assignment of characters with diacritical marks, e.g. á, å, ç, ë, ñ, etc. on the standard telephone keypad array, or the assignment of other non-Latin character sets is outside the scope of this ETS.
