GS1 Application Identifiers Information
Application Identifiers appear after a
Function Code 1 (FNC1) in Code 128, Data Matrix or DataBar Expanded barcodes to encode certain types of information. After
January 1, 2010, multiple AIs may be encoded in
DataBar Expanded barcodes for use in POS systems, which can replace
common UPC and EAN symbols in the same space or less. This allows serial numbers, sell-by dates and other
vital information to be easily verified at the point of sale. Encoding AI
examples are available for
Code 128,
DataBar Expanded and
Data Matrix ECC200 barcodes.
Following are the ways FNC1 can be used to identify Application Identifiers:
- The AI is defined by the digits after the FNC1 character,
which must be the first character in the barcode.
- Multiple AIs may be included in a single barcode symbol without
additional FNC1 characters if variable length AIs (such
as 10, 21 or 92 as defined below) are included last because
the reading device understands the length of the data after each
non-variable length AI.
- If additional AIs are encoded after a variable length AI, an
additional FNC1 is required to define the end of the variable length
AI.
- FNC1 encoding in DataBar is automatic and is only specified
in DataBar Expanded with parentheses.
The following chart provides examples of common AIs as defined by the
GS1 Application Identifier Specification and should be verified
by a
GS1 Member Organization before implementation.
