Product Service Code (PSC)
A four-character federal code that classifies the specific product or service being bought — complementing the NAICS code that sets industry and size standards.
Definition
A Product Service Code (PSC) is the four-character code the government uses to classify exactly what is being purchased on a contract action — a specific supply item, an R&D effort, or a category of service. Where the NAICS code classifies the offeror's industry and sets the small-business size standard, the PSC describes the deliverable itself, and the two are used together across systems such as FPDS and USASpending.
For contractors, PSCs are a powerful market-research tool. Filtering historical awards by the PSCs that match your offerings reveals which agencies buy what you sell, how much they spend, and which vehicles they use.
How this affects your proposal
Build saved searches and pipeline filters on the PSCs that match your offerings, not just NAICS codes — PSCs pinpoint the actual products and services agencies buy.
Common questions about product service code (psc)
What is the difference between a PSC and a NAICS code?
A NAICS code classifies the contractor's industry and sets the SBA small-business size standard. A PSC classifies the specific product or service being purchased. A single contract action carries both.
How do contractors use PSCs?
Mainly for market research: filtering historical award data by PSC shows which agencies buy a given product or service, how much they spend, and through which vehicles.
