The CPID is the GS1 Identification Key used to identify a Component or Part. The CPID will identify a component or part uniquely thus ensuring that it is always identified correctly anywhere in the world. Each component part that is different from another is allocated a separate, unique CPID. The CPID itself has no meaning and this allows the component / part to be looked-up in a database and its associated information be retrieved at any point or location. 

Warning: These Standards for Component Part Identification (CPID) are only to be implemented upon mutual agreement between trading partners, and are explicitly not intended for open supply chain use. If you plan to work with them, we recommend you read and use the Component Part Identification Implementation Guidelines.
