GPC is like a universal language that helps businesses around the world recognise and organise products. This system is used by manufacturers, suppliers, retailers, and online stores to make it easier to find products, share information, manage stock, and analyse markets.
Do I need to allocate GPCs to my products?
In My Numberbank, we have added a field for you to record GPCs against your different products. GPC is also a useful way for you to categorise your products in a globally standardised way. Whilst it isn’t a mandatory field, if you wish to have your product searchable on Verified by GS1 (VbG), you will need to add an appropriate GPC brick against the GTIN.
How does GPC work?
GPC is a rules-based, four-tier system for classifying products into Segment, Family, Class, and Brick. A Brick groups products with common purposes, similar forms, materials, and shared category attributes.

A GTIN can be assigned to only one brick. Though, the same brick can be associated with multiple GTINs.
