GS1 Application Identifier Standard Format

Certain barcode symbologies (including GS1-128, GS1 DataBar Omnidirectional, GS1 DataMatrix and GS1 Composite 2D components) represent standardized GS1 data and require that their data field is provided in GS1 Application Identifier standard format, consisting of a concatenated string of AIs along with their corresponding values.

The AIs are a set of approximately one hundred two-, three- or four-digit prefixes written within parentheses that represent physical attributes and business information, e.g.

• (00) is an eighteen digit SSCC.
• (01) is a fourteen digit GTIN.
• (403) is a variable length routing code.

The following input represents GTIN 0061414199996; Expiration Date 1 January 2010; Batch 123ABC; Serial 1234567890:

(01)0061414199996(17)100101(10)123ABC(21)1234567890

Encoders for barcode symbologies that expect data in GS1 Application Identifier standard format will take care of parsing the input and inserting any necessary FNC1 characters to delimit variable length fields.

GS1 Application Identifier Definitions

ISO/IEC 15418 defines the Application Identifiers and limits associated with each AI. The Application Identifier definitions are also provided in the GS1 General Specifications.
