=== Error correction code ===
{{Main|Error correction code}}
Any error-correcting code can be used for error detection. A code with ''minimum [[Hamming distance]]'', ''d'', can detect up to ''d'' − 1 errors in a code word. Using minimum-distance-based error-correcting codes for error detection can be suitable if a strict limit on the minimum number of errors to be detected is desired.

Codes with minimum Hamming distance ''d'' = 2 are degenerate cases of error-correcting codes and can be used to detect single errors. The parity bit is an example of a single-error-detecting code.
