Create a Case and Generate a Barcode

24 October 2019

Create a Case and Generate a Barcode

After you create your items that are sold to consumers, you can now create the cases that contain these items for shipping/receiving. Follow these steps to create a case that is NOT expected to pass through point of sale. 

GS1 US Data Hub assigns a different GTIN than the GTIN that this case contains, and enable you to generate the ITF-14 or GS1-128 barcode.

Important: Before creating the case, first create the GTIN for the "child" product that will be added to this "parent" case in GS1 US Data Hub.

  1. Click Product, then the Create link.

  2. Product Description – Enter a description of your product. Avoid the use of special characters, such as the pipe "|" and line breaks "CR/LF". One best practice is to use the product description of the item that is contained in the case, followed by the actual number contained in this case, such as "Case of 24". There is a 500-character limit.
  3. Brand Name – Enter the name of the product line that is used with consumers. There is a 70-character limit.
  4. Product Industry – Select the primary industry where the product is sold.
    - CPG = Consumer Packaged Goods (groceries, personal care products, etc.);
    - General = General Merchandise (toys, flooring, appliances, etc.)
  5. Packaging Level – Select "Case" if this packaging contains quantities of just a single GTIN. If quantities of several GTINs are going into this case, you must select "Mixed Case." View the Packaging Level Definitions page for more.

  6. Language – this is the language for the Product Description and Brand Name. The default is "en" - English." If this product’s primary target market uses a local language other than English, you can change it here. Have an additional language to add? Click the "Additional Information" tab to add a second language.
  7. SKU (optional) - Enter the Stock Keeping Unit (SKU), which is assigned to the item by your company and can be alphanumeric. There is a 70-character limit.
  8. Is this item variable measure? – leave this box unchecked. Trade items may be of variable measure either because the production process does not guarantee consistency in weight, size, or length (e.g., meat, whole cheeses) or because the items are created to meet a special order that states a quantity (e.g., textiles ordered by the foot, glass ordered by the square yard).
  9. Can this item be purchased by the consumer? – because you selected "Case" as the packaging level, this box is unchecked by default, and this ensures the ITF-14 and GS1-128 shipping/receiving barcodes are available after you assign a GTIN.

  10. Press Save to save this as a record with the Draft status. You can now add the "child" product this case contains, and assign the GTIN to this case. 
  11. Click the "Add Contents" button on the screen to select the item that is placed into this case. 

  12. The Add GTIN to Container window displays. Click the product you want to add to this case. The row for that item turns gray when selected. Click the "Add to Container" button.

  13. The window closes and the child product displays on the screen. In the Qty field, enter the quantity of this GTIN to be placed into the container, and click the Qty "check" to save this quantity. If you accidentally selected the wrong item, click the item to highlight the row, click the "Remove" button, then click "Add Contents" to select a different item. Once you change the status to In Use and click Save, you cannot change the contents or the quantity.

  14. Now you're ready to assign the GTIN to this case. You have three options:

    a. Auto Assign GTIN – When you select this option, and you have left the box unchecked for "Can this item be purchased by the consumer?," GS1 US Data Hub will automatically assign a GTIN-14 to the case. To learn more about the GTIN-14, read An Introduction to the Global Trade Item Number (GTIN). To summarize, a GTIN-14 is assigned if you have:
    • You selected one of these Packaging Levels: Inner Pack, Case, Pallet or Display Shipper;
    • For Inner Pack or Display Shipper, you selected only one product when you clicked "Add Contents";
    • You didn't change the Prefix displayed in the "Auto Assign GTIN" window (this only applies if your company has multiple prefixes);
    • You left the box unchecked for “Can this item by purchased by the consumer?"

      Note: GTIN-14 uses the same “Item Reference" as the item that was added to this shipping and receiving item. Item References are what determine the number of GTINs that you can assign (also known as your "GTIN Capacity"). So when the GTIN-14 is assigned, the number of "Available" GTINs for your Company Prefix is not reduced. This number is displayed on the GS1 US Data Hub home page (the screen example is shown here).

      Keep in mind that if you select the "Mixed Case" packaging level, the GTIN-14 is NOT assigned, as there are two or more unique GTINs contained in a Mixed Case, and a single Item Reference can't be applied. So the Mixed Case GTIN does use an Item Reference, and does reduce the GTIN capacity.

    b. Assign GTIN from Reserved – Allows you to specify a GTIN from GTINs that you have already reserved GTINs for this product or group of products;

    c. Assign GTIN Manually – Allows you to type the desired GTIN yourself and assign it to a specific product. Also, you will need to calculate the check digit. which is calculated from all the other numbers in the barcode and helps to confirm the integrity of your barcode number. For help, visit ​
  15. After you assign the GTIN, the item moves from Draft to PreMarket status. You can now click the Barcode tab and click the "Preview Barcode" button to generate a “For Placement Only” (FPO) barcode. This watermark barcode is for product and packaging design purposes. To generate the final, scannable barcode, you will need to change the status​ to In Use.

    Note: Please be attentive when placing products "In Use" as the ability to remove/replace them is significantly reduced once they have this status. The upper-level package can only receive the "In Use" status when the child GTIN(s) is "In Use". 

  16. When you have finalized barcode placement within the packaging design, and you're ready to share this product with the marketplace, change the status to In Use - you can now create a barcode that can be scanned.
  17. To view the barcode, click the Barcode tab. The Barcode window displays.

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

    - Barcode Type – The selected barcode symbol. Because you have selected "Case" and unchecked the box for "Item can be purchased by the consumer," the two options are ITF-14 and GS1-128. 

    Adding Application Identifiers: When creating a barcode, only certain barcodes can generate Application Identifiers (AIs), such as the GS1-128. When you select GS1-128, the Application Identifier section displays so you can customize your barcode.  
    Note: Application Identifier AI (01) GTIN is automatically generated from the selected GTIN. The Additional Application Identifiers section allows you to add more AI’s to the barcode (i.e. Batch or Lot Number, Product Date, Packaging Date, Best Before Date, Expiration Date, etc.).  
    - Click Select an AI and type ** to see all available AI’s.  
    - Enter the corresponding info under Application Identifier Value (e.g., choosing **11 Production Date (YYMMDD), you would fill in a date such as 210801 for August 1st, 2021).

    - Size – For the ITF-14 and GS1-128 barcode options, two barcode dimensions are available: optimum ("Target") and Maximum "X-dimensions." The numbers provided are the X-dimension and the minimum symbol height for each of the X-dimensions. An X-dimension is defined as the specified width of the narrowest element of the barcode, and is used together with the symbol height to specify the permissible symbol size. U.P.C. barcodes have a fixed relationship between barcode height and width, so if one dimension is modified, the other dimension must be altered by a proportional amount. ​Do NOT resize or crop these barcodes.  
  18. Click Preview Barcode - View and download your barcode symbol, which is .PNG file. Please note that an EPS (or vector file) is not provided.
    - Export Definition- Download the barcode symbol specifications as a worksheet to be shared with GS1 Standards Professional print vendors.

Q. My prefix is out of capacity. How can I obtain more barcodes?

A. It's not possible to “add capacity” - or add additional GTINs - to an existing prefix when you need more barcodes. If you exhaust the numbering capacity of your GS1 Company Prefix, you can obtain an additional Company Prefix. As your business grows, it may be worth investigating if the additional prefix that you are planning to acquire should have greater numbering capacity. This way, you won’t have to come back as frequently and you may be able to save money over time. If you only need a few more GTINs, another option is to license GS1 US GTINs. Learn more by visiting the GS1 US Get Started Guide.

Packaging Level Definitions (Hierarchy)

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. When viewing the product detail record for a single product, click the "Hierarchy" tab to view the relationships for this product. 

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.
