Step 3 - Enhance Your GTIN Data

The Step 3 - Enhance Your GTIN Data page includes the following attributes. When GS1 US Data Hub View/Use subscribers search for consumer trade items in GS1 US Data Hub, or GS1 global members search the GS1 Registry Platform, they will see the Verified by GS1 check mark if the product detail record contains these attributes:

Product Image URL:

Insert a web address that represents the photo(s) of this product. The address must start with either http:// or https://. If the URL is a valid web address and contains a PNG, JPG, GIF or BMP file, “Validated” will display in green text after you save. If the validation fails, "Validation Failed" will display but the web address will still be saved in GS1 US Data Hub. 


For more details, view this fact sheet.

Global Product Classification (GPC):

This is the “Brick” code associated with your product category, based on the GS1 Global Product Classification (GPC) standard. Visit the GS1 GCP Browser tool displayed on the Step 3 page to identify the GPC for your product. View this GPC Browser instructional module to learn more.

Net Content and Unit of Measure:

Net Content 1: This is made up of two fields:

  • Count: this is the amount of the consumable product of the trade item contained in a package, as claimed on the physical label. For a multi-pack, you should indicate the net content of the total trade item (10, 4, 11.nnn). This number may be represented in whole numbers or up to four decimals.
  • Unit of Measure: this is the type of measure representing the Count, as claimed on the physical label, and may include net weight, volume, count, units, etc. A list of the most common Unit of Measures are available from the pull-down menu.

After you set the product to In Use, the Net Content 1 fields CANNOT be changed. Optional: To add a secondary Net Content that’s displayed on your packaging, such as Unit of Measure in metric, click Add Additional Net Content. You can also add a third Net Content, if desired.

Other Fields on the Step 3 Page:

The following three fields are displayed on the Step 3 - Enhance Your GTIN Data page, but are not required to display the Verified by GS1 check mark:

  • Sub-Brand Name: This is a second level of the brand. This could be a trademark. It is the primary differentiating factor that a brand owner wants to communicate to the consumer or buyer.
  • Product Description - Short: a free form short length description of the trade item that can be used to identify the trade item at retail point-of-sale (POS). This allows for the representation of the same value in different languages you should not enter multiple values. 
  • Label Description: a literal reproduction of the text featured on a product’s label in the same word-by-word order in which it appears on the front of the product’s packaging.
