12 GS1 Identification Schemes / Encoding Schemes and Their Uses

Published by on

GS1 is a non-profit, global organization that creates and maintains global standards for business-to-business and supply chain communication. In essence, a standard is created so that when a barcode is scanned or an RFID tag is read, the stored data can be interpreted and understood. Without standards, a custom barcode could be created and placed on a product, but without a standard in place and software to make sense of that number, it is simply a number. However, with GS1 standards to help interpret that data, the barcode or RFID tag’s EPC number becomes a unique set of data that provides information about the associated asset.

GS1 currently has 12 Identification Schemes, which are also called encoding schemes or identification keys. They are CPID, GTIN, GIAI, GLN, SSCC, GSIN, GINC, GRAI, GDTI, GCN, GSRN, GMN. These identification keys are used for identifying specific items or assets across the world, and that key data is assigned and kept in a global registry managed by GS1.

When a company signs up with GS1, they are assigned a company prefix and then asked to upload information about their items/assets that will need to receive a GS1 Verified number. GS1 asks companies to upload 7 core product attributes for most items/assets, which includes GTIN (each item must be assigned a GTIN if not already), brand name, product description, product image URL, global product classification code (each item must be categorized with a GPC), net content, unit of measure, and country of sale.

After all the item/asset data is uploaded to GS1’s secure Cloud, each product can be assigned a number based on the Identification Key / Identification Scheme that the company is using. The type of Identification Scheme or Encoding Scheme that a company will use depends on what the current practice is in that industry as well as the type of product/service that needs to be identified.
