Question

alphanumeric Back in the 1950s, we always spoke our phone numbers in alphanumeric form, using the letters printed on the dial: for example, “TErrace 5-6642,” instead of “835-6642.” ˌælfənuˈmɛrɪk

Accepted Answer

Having or using both letters and numbers. Alphanumeric passwords are much harder for a hacker to crack than plain alphabetic passwords, since the number of possible combinations is so much greater. License plates usually contain both letters and numbers, since, for a big state or country, the plate wouldn't be large enough to fit enough numbers for everyone. In computing, the standard alphanumeric codes, such as ASCII, may contain not only ordinary letters and numerals but also punctuation marks and math symbols
