What is GPC?
To ensure products are classified correctly and uniformly, GDSN uses GS1 Global Product Classification (GPC), a system that gives buyers and sellers a common language for grouping products in the same way, everywhere in the world.
This improves the Global Data Synchronisation Network's data accuracy and integrity, speeds up the supply chain's ability to react to consumer needs, and contributes to breaking down language barriers. It also facilitates the reporting process across product silos.
The foundation of GPC is called a "Brick;" GPC bricks define categories of similar products. Using the GPC brick as part of GDSN ensures the correct recognition of the product category across the extended supply chain, from seller to buyer. Bricks can be further characterised by Brick Attributes.

GPC and UNSPSC
Under the leadership of the user community, GS1 launched an initiative to align GPC with another classification system managed by GS1, the United Nations Standard Products and Services Code (UNSPSC). UNSPSC is a global, multi-sector classification system supporting primarily spend analysis and procurement. Download an update on GPC-UNSPSC alignment.
