Global Document Type Identifier (GDTI)
The Global Document Type Identifier (GDTI) is used to uniquely identify a document type or an individual document.
The optional serial component is assigned to a single document for its lifetime. When combined with a
Global Document Type Identifier 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.
