GS1 Application Identifiers

There are many industries which follow the GS1 (UCC/EAN) identification guidelines. In order to attribute meaning to data encoded within a bar code symbol, an Application Identifier (AI) prefix code used. Aside from denoting the meaning, this prefix also indicates the format of the data that follows it (data field). There are AIs for identification, traceability, dates, quantity, measurements, locations, and many other types of information.

For example, the AI for batch number is 10, and the batch number AI is always followed by an alphanumeric batch code not to exceed 20-characters.

The GS1 Application Identifiers provide an open standard which can be used and understood by all companies in the trading chain, regardless of the company that originally issued the codes.
