To prove something to be sound or logical. Also to certify conformance to an accepted standard. Contrast with verify
For example, data entry validity checking determines whether the data make sense (numbers fall within a range, numeric data are all digits, etc.), but "validity" checking does not "verify" that the data are correct.

In practice, the terms "validate" and "verify" are used synonymously. See validity checking
, check digit
and HTML validator
