Packaging Level Definitions (Hierarchy)

1 November 2019

Packaging Level Definitions (Hierarchy)

Here is a brief summary of the Packaging Level options in GS1 US Data Hub. You must first enter the "Each" unit, and then the "Inner Pack," etc. if you are adding these to the "higher level" units. For more details, watch the Packaging Level module in the GS1 US University Learning Management System (sign in is required). This brief module explains the packaging hierarchy, how the GTIN-14 is generated, and how you can generate ITF-14 and GS1-128 barcodes. 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 is unchecked for “Can this item be purchased by the consumer?” but you can check this box.

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. 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.

How to Display the Verified by GS1 Check Mark

Complete and accurate product data results in a more efficient and seamless supply chain - as well as a more positive shopping experience for consumers. 

You can have the Verified by GS1 (VbG) check mark display to GS1 US Data Hub Product View/Use subscribers when they search for a product in the GS1 Registry Platform. These subscribers include retailers, marketplaces, solution providers, agencies and others. Verified by GS1 enables the verification of a product’s identity based on a set of seven core product attributes.

To learn how to enter these attributes, view this GS1 US video.

If you save the following attributes with your product detail record, the VbG check mark will display when the GTIN is searched through the GS1 Registry Platform:
- Brand Name
- Product Description
- Product Image URL (make sure the address starts with http:// or https:// - view this fact sheet)
- Global Product Classification (GPC) (view the GS1 GCP Browser for more details)
- Net Content and Unit of Measure (view a list of valid Unit of Measure codes)
- Target Market (or Country of Sale - view a list of Country codes)

Product Image, GPC, Net Content and Target Market are available from the Additional Information tab (Enhanced Product Information section).

GS1 US Data Hub currently provides access to more than 30 million products, making it valuable as part of a retailer’s data quality and product sourcing efforts.

Learn more by visiting the Verified by GS1 page on the GS1 US site.

Add Users and Assign Roles: GS1 US User Portal

20 January 2020

Add Users and Assign Roles: GS1 US User Portal

When a new account is set up, the new user is assigned the General Administrator role. This administrator can then assign other users to the GS1 US Data Hub | Product role, so this new user can create and manage barcodes. Unless the Product Create/Manage role is assigned, the "Product" link will be grayed out for the user.

Watch a module on the GS1 US University Learning Management System for a demonstration on how to log in to the User Portal, add a user and assign roles (sign in is required). Click the GS1 US Data Hub & User Portal category, then "Help Resources," scroll down to "How to Add New User and Assign Roles" and click "Launch".

Need to add available users to your subscription? Visit our online application (click the "Are you an existing GS1 US Customer..." link).

Add the Product Create/Manage Role:

One of the most frequently assigned roles in GS1 US Data Hub is the Product Create/Manage Role. To assign this role to an existing user, the General User Administrator or Product Administrator can log in to the User Portal and take these steps:

1.  Locate the user using the filter box and when the user information displays, click the row for that user. Then click the "Edit Roles" link next to the "Roles in [Company Name] header. Scroll down and check the box for "Product Create/Manage."

2. Click "Save."

When the user logs in to GS1 US Data Hub, the Product tab is "enabled" - that is, the Product tab will no longer be grayed out, and the user can now click "Product" and add a product and generate a barcode. This user can also maintain product data, generate other barcodes in GS1 US Data Hub, such as ITF-14 and GS1-128 for cases, pallets, etc., and export this data so it can be entered into the company's product database.  

Want to Add Additional Product Create/Manage Roles?
