Assign AI(253) to identify a Global Document Type Identifier (GDTI). The number is formed with your allocated GS1 Company Prefix, the document type reference which is assigned by the document user, and the Check Digit. The number is allocated in the same way as you allocate a number for a retail trade item. Refer to Numbering Trade Items If you have obtained a prefix to allocate twelve-digit GTINs either directly from GS1 US , GS1 Canada or via GS1 Australia, you must add a filler zero to the front of the prefix after the Application Identifier.

The optional serial component is assigned to a single document for its lifetime. When combined with a GDTI it uniquely identifies an individual document. The serial component field is numeric and may contain up to seventeen digits. The issuer of the document determines the serial component.
