GTIN Allocation Assistant

GTIN Allocation Rules Made Simple

Globally unique product identification and correct GTIN allocation is foundational to an efficient and traceable supply chain. However, GTIN allocation rules can be confusing and a wrong decision may result in issues with product listings or the need to repackage or withdraw products.

Make the right decisions quickly and easily with GS1 Canada’s GTIN Allocation Assistant, a decision support tool available for both desktop and mobile devices, for determining if proposed product or packaging changes require a new GTIN.

GTIN Allocation Assistant leverages content in ECCnet Registry to walk you through a series of simple questions and provide a clear decision.

GTIN Allocation Assistant is based on global standards, aligned with local regulations and created in collaboration with Canadian manufacturers and retailers.

The tool is currently optimized for consumer packaged goods (CPG) products found in grocery stores (except over-the-counter pharmaceutical products).

For additional support on whether a product change necessitates a new GTIN, please consult the global GTIN Management Standard or contact the GTIN Ombudsman.

The Value of GTIN Allocation Assistant

Data Excellence

Our commitment to data excellence ensures bilingual product data is perpetually cleansed and updated, increasing accuracy and building trust between trading partners.

Ensuring all products are correctly allocated new GTINs when required means that product data shared between trading partners is accurate and reliable.

Reduced Financial Risk

By helping you identify when a new GTIN is needed, GTIN Allocation Assistant also helps you distinguish specific product variations such as seasonal or promotional products.

In the event of a product recall, being able to isolate just the affected range, rather than recalling your entire stock of that product, can minimize the financial impact.

Standardized Information

GTIN Allocation Assistant leverages GS1 global GTIN management rules to determine whether or not your product updates require a new GTIN, ensuring consistency in the decision-support process based on global standards.

Increased Operational Efficiency

A streamlined process for determining whether or not you need a new GTIN reduces both confusion and the chances of making a wrong decision that can cost you money and delay product listings.
