GEPIR (Global Electronic Party Information Registry) provides online access to basic contact information for companies that are members of GS1. These member companies use GS1's globally unique numbering system to identify their products, physical locations, and shipments. By typing a product's bar code number into GEPIR, users can find the code owner's contact information. Physical location numbers and shipment numbers can also be used as search criteria.
This service is accessible directly using a web interface or programmatically using a SOAP-based API.
