billypnats Posted June 23, 2009 Share Posted June 23, 2009 You know on some infomercials, its like 1-800-203-MAYS ? HOw do you enter that on your phone? and also some government's automated services ask you for things like postal code which have letters on it, how do you enter that? I know that theres like 3 letters for each digits, but how do they differentiate between them? how do they know if you meant 2 or A or B or C?

dezdimona Posted June 23, 2009 Share Posted June 23, 2009 phone numbers are divided into area codes.Each area code has certain prefexes assigned to it,so when you just use letters the mainframes automatically know what is and what isn't a viable number.
