What is a GS1 Application Identifier?
A GS1 Application Identifier (AI) is the two-to-four-digit prefix that defines the meaning and format of the data that follows it in an element string. For example (01) marks a GTIN, (10) a batch or lot number and (17) an expiry date in YYMMDD form. Fixed-length AIs have a set number of characters; variable-length AIs run until an FNC1 (Group Separator) or the end of the data.
