gcn - Global Coupon Number

The GCN is the GS1 Identification Key used to identify a coupon. The GCN will identify a coupon uniquely thus ensuring that it is always identified correctly anywhere in the world. Each coupon that is different from another is allocated a separate, unique GCN. The GCN itself has no meaning and this allows the coupon to be looked-up in a database and its associated information retrieved at any point or location. The GCN is normally assigned by the Coupon Issuer using Application Identifier.
