Alphanumeric

From Academic Kids

Generally speaking, the term alphanumeric refers to anything that consists of only letters and numbers. For example, "ABC123" is an alphanumeric expression. The term may also refer to a device that handles such expressions (contrary to letters-only or numbers-only processing equipment). In telecommunication and computer science, an alphanumeric entity is specifically defined as a character string that contains only letters and digits (and sometimes a few other characters, typically punctuation marks).
