Create a Product and Generate a UPC-A Barcode

24 October 2019

Create a Product and Generate a UPC-A Barcode

If you have licensed a GS1 Company Prefix, you can create products and assign your available GTINs to them, so you can generate a barcode image.

Note: if you licensed a single GS1 US GTIN, instead of a GS1 Company Prefix, your product is already saved in GS1 US Data Hub with the In Use status. Visit the GS1 US GTIN article to learn how to generate your barcode, create a case, etc.

Follow these quick steps to create a consumer trade item that can be purchased at a store or online:

  1. Click Product, then the Add New Product link on the right.

  2. Product Description – This is a "functional description" to share with retailers, not the marketing description that is used for consumers. A best practice is to include brand name, type of product, variation (color, flavor, scent, etc), and net contents. There is a 200-character limit on this field.

  3. Brand Name – Enter the name of the product line that is used with consumers. There is a 70-character limit.

  4. Product Industry – This will help retailers and other Product View/Use subscribers filter by “industry” when searching for products.
    CPG = Consumer Packaged Goods (groceries, personal care and beauty products, home cleaning products, etc.);
    General = General Merchandise (toys, flooring, appliances, etc.)

  5. SKU (optional) - This is the Stock Keeping Unit that your company may assign to products to help track inventory. The SKU can be alphanumeric. There is a 70-character limit. You can add or change the SKU for this product, even after you set the status to In Use.

  6. Packaging Level – "Each" is the default, and is generally the consumer unit sold at check out or online. To learn about other packaging level options, view this Packaging Level article.

  7. Purchasable by Consumer? – “Yes” is the default selection when you select the “Each” packaging level. Selecting “Yes” will make the UPC-A barcode image available in a later step. 

  8. For Shipping Purposes Only? – Keep "No" selected, as this is the default when “Yes” is selected for Purchasable by Consumer?. You should only select “Yes” if the item is a shipping and receiving trade item, and NOT sold to consumers at retail or online.

  9. Variable Measure? – Keep "No" selected, as most products are fixed measure trade items, not variable measure trade items. A variable measure trade item does NOT receive the GTIN-12. A product that has different sizes, such as jars of sauce in 10, 20 and 30 oz jars, is NOT a variable measure trade item. These three products are fixed measure trade items that require three unique GTINs. 


  10. Press Save and Continue. This product detail record is in the Draft status. The Step 2 page displays.

  11. Now you can assign the GTIN. Click the Let Us Assign Your GTIN button. GS1 US Data Hub will assign the next available GTIN to this product. This available GTIN is displayed under the Your GTIN heading as both a GTIN-12 and a GTIN with 14 digits, with two leading zeroes (which is how it's stored in databases).

    Already have a GTIN to assign to this product? Then click the Choose a Specific GTIN button and type the desired GTIN yourself. The Company Prefix is already populated. Note: The GTIN-12 for an "Each" item must start with two fill zeroes (00), as this is the 14-digit representation of the GTIN that would be stored in a database.

    Optional: Generate a For Placement Only barcode. 
    After you assign the GTIN, the item moves from Draft to PreMarket status. You can now click the Barcode tab to generate a “For Placement Only” (FPO) barcode image for product and packaging design purposes only. You will be able to generate a scannable barcode image (PNG file) after you change the status​ to In Use.

    Optional: Add Additional Product Information. 

    While the product is in the PreMarket status, you can add other product information in Step 3 and Step 4, such as net contents and net weight. Some of these key product attributes cannot be changed after you set the status to In Use. 

    Click the Verified by GS1 article to learn more about the attributes associated with the Verified by GS1 program and the GS1 Registry Platform.

  12. When you're ready to share this product with the marketplace, click the Set Status to In Use button. 

    You can now create a barcode that can be scanned by your customers.

  13. To generate the barcode, click the View Barcode button.   

    The Barcode screen displays:

    - Application Area – This is the environment in which the barcode will be scanned.  The list of available application areas is based on the details for this product detail record.

    - Barcode Type – The selected barcode symbol. UPC-A is the default if "Each" is the Packaging Level, "Yes" is selected for "Purchasable by Consumer," and Application Area is "General Retail/Grocery."

    - Size – You have three choices for the barcode dimensions: the optimum ("Target") size, minimum size that can accommodate all scanners, and maximum size. 

  14. Click Preview Barcode then click the Download button to download a PNG file of the barcode image to your computer. Note: an EPS or vector file format is not available. To print this barcode using an Avery label template, click the Print button. You can also click the "Export Barcode Definitions" button to share the barcode symbol specifications with a GS1 Standards Professional print vendor.

Packaging Level Definitions (Hierarchy)

1 November 2019

Packaging Level Definitions (Hierarchy)

Here is a brief summary of the Packaging Level options available in GS1 US Data Hub. It's based on a hierarchy, so you should enter the "Each" unit first, and then "Inner Pack," and so on, if you need to add these units as "children" into the higher level "parent" units. To view a product's relationships, click a product detail record from My Products, then scroll down to view the "Product Hierarchy" relationships. 

For more details, watch the Packaging Level module in the GS1 US University Learning Management System (sign in is required). More details are also available in the Product Create Manage User Guide.



The lowest level of the item hierarchy intended or labeled for individual resale. Generally this is the consumer unit sold at check out or online. This item would be assigned a GTIN-12 (U.P.C.).

Example: a jar of jam
Inner Pack   Intermediate package of multiples of the same trade item or a predefined assortment of trade items (representing a single GTIN). When you select Inner Pack, the box on the screen is UNCHECKED for “Can this item be purchased by the consumer?”.  In other words, this inner pack is NOT being sold to consumers. Optionally, you can check the box for this field if the inner pack is being sold to consumers.

Example: four jars of jam for shipping/receiving only.
Case   A standard shipping unit that contains “eaches” (packaged either individually or grouped as an inner pack). All of the items in a case must have the same GTIN.

Example: a case containing 8 jars of strawberry jam.
Mixed Case   Contains more than one type of “each,” and must contain more than one GTIN. The case can contain eaches or inner packs.​

Example: a case that holds 4 jars of strawberry jam and 4 jars of blueberry jam.
Pallet   A shipping unit that contains either cases, inner packs, or eaches. It must contain one GTIN regardless of the number of items in the grouping.

Example: a pallet containing 18 cases of strawberry jam.
Mixed Pallet   A shipping unit that can contain any combination of cases, inner packs, and/or eaches and must contain more than one GTIN.​

Example: a pallet containing 9 cases of strawberry jam and 9 cases of blueberry jam.
Display Shipper   A shipping unit that is a self-contained display. It can contain a single type of “each” or multiple types of eaches.​

Example: a promotional display containing both strawberry jam and blueberry jam.
Case as Each   Designed for goods that are shipped as a case, but the contents of the case are NEVER offered for sale on their own. This is used by industries such as foodservice that need to designate the case as its lowest orderable unit. The contents inside are neither assigned GTINs, nor are they sold at checkout or online.​ 

Example: a 25 lb. pack of bulk mushrooms.

Step 3 - Enhance Your GTIN Data

9 February 2021

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 the 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 be still be saved in GS1 US Data Hub. 


For more details, view this fact sheet.

Global Product Classification (GPC):

This is known as the “Brick” product code associated with your product category, based on the GS1 Global Product Classification (GPC) standard. You can click the link for the GS1 GCP Browser tool on the Step 3 page to identify the GPC for your product.

Example: 30002827

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.

For more details, view a list of valid Unit of Measure codes.

Target Market(s):

This is also known as Country of Sale. Select the country or region that represents the target market(s) for this product. You can make up to 50 selections. View a list of Country codes.

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. 

Step 4 - Add Product Dimensions

9 February 2021

Step 4 - Add Product Dimensions

When you add a new product, the optional Step 4 - Add Product Dimensions screen enables you to enter physical dimensions: height, width and depth, as well as Net Weight and Gross Weight. As defined in the GS1 Packaging Measurement Rules Standard, measurements are based on whether the items is a:​

  • Consumer trade item, meaning it is to pass through retail point-of-sale (POS);or​ 

  • Non-consumer trade item, meaning it is for general distribution scanning. This includes outer cases up to the largest form of bulk packaging for trade items.

Consumer Trade Items:

In GS1 US Data Hub, these are items in which “Yes” ​was selected for Purchasable by Consumer? 

Product Dimensions:​

Please refer to the GS1 Package and Product Measurement Standard for detailed instructions, but below is some general measurement guidance.​

First, determine the “Default Front” of the product. GS1 Standards define the Default Front as “the surface with the largest area that is used by the manufacturer to ‘sell’ the product to the consumer.”  ​

​You can then determine the height, width and depth of the item. While facing the Default Front, you must measure:​

  • Height: from the base to the top​

  • Width: from the left to the right​

  • Depth: from the front to the back

Product Weight:

Net Weight - Net is the weight of the product itself. ​This does not include the product’s container packaging. For example, the weight of the soup you pour out of the can.​

Note: Net Weight cannot be changed for a product set to In Use. Also, if Net Weight is entered, the Gross Weight must also be entered. The Net Weight cannot exceed the Gross Weight.​

Gross Weight - Gross is the weight of the product plus the weight of its container or packaging. For example, the weight of the jam contents plus the jar itself. 

Note: Gross weight can be changed if does not exceed 20% of the original weight for a product set to In Use.

Non-Consumer Trade Items:

Non-consumer trade items are identified with a GTIN and are intended for General Distribution scanning. This includes outer cases up to the largest form of bulk packaging for trade items.​ 
​In GS1 US Data Hub, these are items in which “Yes” ​was selected for For Shipping Purposes Only? 

Product Dimensions:​

Please refer to the GS1 Package and Product Measurement Standard for detailed instructions, but below is some general measurement guidance.​

First, determine the “Natural Base” of the item before determining the height, width and depth of the item. The Natural Base is the natural underside of the packaged item pre-shipment (e.g., case). After you determine the Natural Base you can then measure:​

  • Height: the distance between the Natural Base of the non-consumer trade item and the top​

  • Width: the shorter side of the natural base of the non-consumer trade item​

  • Depth/Length: the longer side of the natural base of the non-consumer trade item

Product Weight:

Gross is the weight ​of the current packaging, which would include the gross weight of items ​contained in this packaging.
