GSIN (Goods and Services Identification Number)

The Goods and Services Identification Number (GSIN) is Canada's national procurement commodity code, used by the Government of Canada to categorise what it buys and to match supplier capabilities to open opportunities on the federal purchasing portal.

What is GSIN?

GSIN is a hierarchical code system developed by Public Services and Procurement Canada (PSPC) to group similar goods and services into commodity categories for federal purchasing. Suppliers register on the Buyandsell.gc.ca portal and select the GSIN codes that match their offerings; the system then uses those codes to route relevant bid solicitations and standing offer notices to registered vendors. The code structure organises categories by commodity type, covering everything from office supplies and IT equipment to professional services and construction-related goods.

GSIN sits alongside naics-north-american-industry-classification-system, which classifies the industry of the vendor rather than the product being purchased. Both codes appear in Canadian procurement registration, and suppliers bidding on Canadian federal contracts benefit from having accurate entries in both systems. Unlike unspsc, which is an international standard used across UN-system procurement, GSIN is specific to the Canadian federal government and is not used by provincial or municipal buyers.

Why GSIN matters for bidders

Registering the right GSIN codes on Buyandsell.gc.ca is the mechanism by which the Canadian federal government routes solicitation notifications to your firm. A supplier that registers broad or inaccurate codes will either miss targeted opportunities or receive irrelevant notices that waste evaluation time. The discipline is to browse the GSIN commodity tree on the portal, identify the most specific categories that match your real product or service lines, and then subscribe to notifications for those codes. Suppliers entering the Canadian federal market for the first time should treat GSIN registration as the first practical step before searching for active opportunities, because without registered codes, the platform's matching system cannot connect you to relevant solicitations.

FAQ

Is GSIN the same as UNSPSC?

No. GSIN is Canada's own federal procurement commodity code, while UNSPSC is an international standard maintained by GS1 US for UN-system and other global procurement. The two systems are separate and there is no official mapping between them.

Where do I register GSIN codes?

GSIN codes are registered on the Buyandsell.gc.ca supplier portal, which is the Government of Canada's main procurement marketplace for federal opportunities.

Does GSIN apply to provincial procurement in Canada?

No. GSIN is specific to the federal government. Provincial and territorial procurement systems use their own classification approaches, which vary by province.
