Companies must subscribe to a data pool, which stores the product information, to transmit product information on the GDSN. There are 44 data pools tested and certified by GS1 Global, including Salsify, GS1 U.K., and GS1 Canada. While it is not necessary to have contracts with multiple data pools, consider whether a data pool offers global market data connections.
Some companies also choose to purchase a machine-to-machine (M2M) provider, which are software packages that both connect to the GDSN data pool and streamline the process of moving data. Not all data pools, however, offer this service or maintain certification programs.
GS1 recommends that companies complete a small, controlled data pool trial before choosing a provider.
