Alphanumeric is a description of data that is both letters and numbers. For example, "1a2b3c" is a short string of alphanumeric characters. Alphanumeric is commonly used to help explain the availability of text that can be entered or used in a field such as an alphanumeric password.

Tip

A character that is not a letter or number is considered a non-alphanumeric character.
