GS1 Application Identifiers (GS1 AIs)

 

GS1 Application Identifiers(GS1 AIs) act like a code list of generic and simple data fields for use in multi-sector and international supply chain application. Each GS1 AI consists of two or more digits and provides the definition and structure of the data field encoded in a GS1 DataCarrier. The data structure is either numeric or alpha-numeric and of fixed or variable length. AIs are finite set of defined identifiers used to connect physical and logical things to information or business messages related to them. A GS1 Application Identifier (GS1 AI) exists for each GS1 Identification (ID) Key, allowing it to be encoded in GS1 BarCodes or EPC/RFIC tags. The GS1 AIs associated with the differed GS1 ID Keys are as follows:

 

A GS1 Application Identifier (GS1 AI) exists for each GS1 Identification (ID) Key, allowing it to be encoded in GS1 BarCodes or EPC/RFIC tags. The GS1 AIs associated with the differed GS1 ID Keys are as follows:

 

GS1 Application Identifier GS1 Identification Keys
01 Global Trade Item Number (GTIN)
414 Global Location Number (GLN) – Physical Location
00 Serial Shipping Container Code (SSCC)
8003 Global Returnable Asset Identifier (GRAI)  
8004 Global Individual Asset Identifier (GIAI)  
8018 Global Service Relation Number (GSRN)
253 Global Document Type Identifier (GDTI)  
402 Global Shipping Identification Number (GSIN)  
401 Global Identification Number for Consignment (GINC)  

 

Supplementary data is often associated with a GS1 ID Key in particular GTINs, for example, expiration dates, batch or lot numbers and serial numbers. The Data Structure for dates is a fixed field of 6 numerals – the first two represent the year, the middle 2 the month and the last two the day. For example the day July 26, 2011 is encoded as 110726. The data Structure for both Batch or Lot Number and Serial Number is a variable field consisting of no more than 20 numeric or alpha-numeric numbers.

 

GS1 AI Data Content Data Structure
11 Production Date N1 N2  N3 N4 N5 N6 (YYMMDD)
13 Packaging Date 4 8 0 N1 N2  N3 N4 N5 N6 (YYMMDD)
15 Best Before Date

4 8 0 N1 N2  N3 N4 N5 (YYMMDD)
17 Expiration Date 4 8 0 N1 N2  N3 N4 N5 N6 (YYMMDD)
10 Batch or Lot Number  X1X2... X20 (alphanumeric – variable)
21 Serial Number X1X2... X20 (alphanumeric – variable)

 

Besides the use of GS1 AI (414) with the GLN to identify physical locations, other GS1 AIs can to used with the GLN to identify a party. The following table provides the use of GS1 AIs with a GLN and their definition

 

GS1 AI Identification of Keys of Location
414 Identification of Physical Location
410 Ship to – Deliver to
411 Bill to – Invoice to
412 Purchased from 
413 Ship for – deliver for – Forward to  
415 Invoicing Party

 

GS1 AIs present a standardized way to encode information in a single GS1 DataCarrier.
