Combinations Description Addition
AI (01) Must start with 9 for variable units
+ AI (310n) or AI (320n) For declaration of the Weight n = 0..9
+ AI (11), AI (13), AI (15), AI (17) For the Date
Table 9: AIs in GS1 DataBar Expanded / Expanded Stacked Codes
If the date is not required this order of AIs still leads to a better barcode representation.
5.3.2 AIs with Variable Lengths
5.3.2.1 AI (01) and Price
Combinations Description Addition
AI (01) Must start with 9 for variable units
+ AI (392x) For the price x = 0..3
or + AI (393x) For the price in the ISO currency format x = 0..3
Table 10: Variable length AIs in RSS Expanded / Expanded Stacked Codes
5.3.2.2 AI (01)
► If AI(01) is needed in the barcode, please ensure it is the first AI encoded (for optimal data
representation).
5.4 EAN.UCC Composite Symbology
The Composite Symbology was designed to hold primary data (like the GTIN or Shipping Container
Code) in the linear symbol and additional data in the 2D Composite Component. For specific AI
combinations in the 2D add-on symbol it is possible to perform a data compression (as shown
below). This leads to a higher data density (= smaller barcode or more encode able characters).
5.4.1 Compressed Sequences of AIs
The following AI-sequences can be compressed for higher data efficiency:
Combinations Description
AI (11) + AI (10) Date and Lot-Number
AI (17) + AI (10) Expiration Date und Lot-Number
Table 11: AIs in Composite Codes
5.4.2 AI (90)
AI (90) and the following data (which starts with an upper-case letter or a digit) may be used for
encoding of FACT IDs. Compression takes place only if AI(90) is the first data element of the
sequence.
