GIAIs or Global Individual Asset Identifiers are the GS1 Identification Key used to uniquely identify a specific asset.

GIAIs are variable length up to 30 alpha numeric characters composed of a GS1 Company Prefix and an Individual Asset Reference. The GIAI is assigned by the owner of the asset and may be bar coded using Application Identifier (8004).

The GIAI is constructed as:

GS1 Company Prefix >            < Individual Asset Reference >
N1... Ni
Xi+1... Xj (j<=30)
