A GS1 element string looks like one long number, but it is really several fields concatenated: each one opens with an application identifier that says what the digits after it mean. This tool splits the string back into those fields and names them, so you can check a case label without going to the spec.

Nothing you paste is stored. The code is sent to our decoder, decoded, and returned.
