GSIN (Goods and Services Identification Number)

The Goods and Services Identification Number (GSIN) is Canada's national classification code for federal procurement. It is used by Public Services and Procurement Canada (PSPC) and other federal departments to categorise goods and services on tender notices, standing offers, and supply arrangements published on the Buyandsell.gc.ca portal.

What is GSIN?

GSIN codes are assigned by the Canadian government to organise federal purchasing into recognisable commodity groups, making it easier for suppliers to identify relevant opportunities and for buyers to group requirements. Each GSIN code corresponds to a defined category of goods or services, such as information technology, professional services, or scientific equipment. The code appears on solicitation documents published through the Government Electronic Tendering Service (GETS) on Buyandsell.gc.ca.

GSIN coexists on Canadian federal tenders with naics codes, which classify the industry of the supplying firm. While NAICS describes who the supplier is, GSIN describes what is being bought, making the two systems complementary rather than duplicative. Canada also participates in the WTO Government Procurement Agreement, so large contracts above threshold values are notified internationally, and international suppliers may encounter GSIN codes when monitoring Canadian procurement feeds for opportunities aligned with their commodity-code strengths.

Why GSIN matters for bidders

Suppliers targeting Canadian federal procurement need to understand both GSIN and NAICS to register correctly and filter relevant opportunities. Buyandsell.gc.ca allows suppliers to set up alerts by GSIN category, so selecting the right codes is the practical step that controls which tender notices arrive in a firm's inbox. Unlike unspsc, which is used by UN agencies globally, GSIN is specific to Canada and does not cross over to other markets, so firms bidding internationally must maintain separate code profiles for each jurisdiction.

FAQ

Is GSIN used outside Canada?

No. GSIN is a Canadian government standard and applies only to federal procurement in Canada. Suppliers pursuing US federal work use naics and psc codes instead; UN procurement uses unspsc; EU procurement uses cpv.

Where do GSIN codes appear in a solicitation?

GSIN codes appear in the header section of solicitation documents published on Buyandsell.gc.ca, alongside the NAICS code, the contracting authority, and the estimated value.

Do I need a GSIN to bid on Canadian federal contracts?

You do not enter a GSIN as a supplier; rather, the buying department assigns the GSIN to the requirement. As a supplier, you use GSIN codes to filter and subscribe to relevant opportunities on Buyandsell.gc.ca.
