Historically, GM dealers used CD-based systems or the legacy GMWizard. Today, the "Global" designation is critical. GM merged its North American, European, and Asian part databases into a single, unified platform.

The GM Global Electronic Parts Catalogue (EPC) is a centralized, digital parts-information system used across General Motors’ global dealer network, independent repair shops, parts distributors, and other aftermarket stakeholders. It provides standardized identification, cataloging, and ordering information for vehicle parts and assemblies across GM’s brand portfolio and global markets. The EPC aggregates technical parts data, illustrations, fitment and application details, service bulletins, supersessions, part interchangeability, and pricing references to support accurate parts selection, inventory management, repair procedures, and warranty processing.

Automotive parts are constantly revised. The EPC automatically handles part number changes (supercessions). If you search for an obsolete number, the system provides the new, interchangeable part and notes if it "replaces" or is "replaced by" another number.
