A Product Service Code (PSC) is a 4-character code used by US federal agencies on contract actions to identify what is being bought — a product, a service, or research and development.

How is PSC different from NAICS?

NAICS classifies the contractor's industry. PSC classifies what the government is purchasing on a specific contract. Federal opportunities on SAM.gov list both.

Where does this PSC list come from?

We use the GSA's official Product and Service Codes Manual, filtered to only show codes that are currently active.

Can I search by category?

Yes — type a category keyword (for example 'IT services', 'construction', 'medical') and the lookup returns every active PSC code that matches.
