Frequently Asked Questions

Maintaining accurate and up-to-date information on your prefix is important to your business. Updating the information associated with the prefix is key to ensuring that your trading partner knows who they are doing business with and creates company recognition for consumers. When an update is made with GS1 US®, the update will appear in GEPIR® and GS1 US Data Hub®| Company. These include updates to the:

• Address
• Business entity structure (LLC, Inc., etc.)
• Company name
• Ownership (Merger or acquisition of a company)

• Ensure GEPIR and GS1 US Data Hub | Company maintain accurate information
• Accurately represent the brand owner of the product
• Enable accurate traceability of the product throughout the supply chain
• Allow your barcodes to be accepted by retailers globally

Company Prefix(es) issued in accordance with GS1 Standards (“GS1 Company Prefix(es)”) are fundamental to creating unique - GTINs (Global Trade Item Numbers) - U.P.C. labels - EDI (Electronic Data Interchange) communication - Data Synchronization - Serialized Shipping Container Codes (SSCC) Coupons.

A GS1 Company Prefix is issued to only one company by GS1 US and CANNOT be shared by multiple organizations.

A GS1 Company Prefix uniquely identifies the company, so if multiple companies unknowingly use the same GS1 Company Prefix, it can cause confusion among trading partners, making unique product identification and product traceability problematic and potentially unattainable. In the event of a merger, acquisition or divesture, it should be clear which party will have rights to use the GS1 Company Prefix. Providing notification to GS1 US will help ensure proper registration.

Use GEPIR, the international database tool, to confirm the proper registration of GS1 Company Prefixes. Generally, GS1 Company Prefixes are issued to the company and not a brand.
