What are PSC Codes?

Product Service Codes (PSC) are the standard codes used by federal agencies to describe and categorize the specific products and services being purchased through government contracts.

Procurement Classification

Categorize government purchases by the specific products or services being acquired, not by the type of company selling them.

Opportunity Matching

Find contracts for your specific products and services. PSC codes help match vendors with relevant procurement opportunities.

PSC Code Hierarchy Example

R Professional, Administrative & Management Support Level 1
R4 Professional & Allied Services Level 2
R408 Program Management/Support Services Level 3
R425 Engineering & Technical Services Level 3

Unlike industry codes, PSC codes classify the specific product or service being purchased, using alphanumeric characters that become more specific at each level.

Frequently Asked Questions

Everything you need to know about PSC codes and government contracting.

A PSC (Product Service Code) is an alphanumeric code used by federal agencies to categorize the specific products and services being purchased. Unlike industry classification codes (like NAICS) that describe what your company does, PSC codes describe what is being bought. For example, "R425" represents Engineering & Technical Services.

Search our directory using keywords that describe your products or services. For example, search "engineering" to find R425, or "software" to find relevant IT service codes. PSC codes use a hierarchical structure (like R → R4 → R425) where each level becomes more specific. Browse the major categories or search directly for what you offer.

PSC codes describe what is being bought (the product or service), while NAICS codes describe who is selling it (the type of business). Example: An engineering firm (NAICS 541330) might bid on an "Engineering Services" contract (PSC R425). Government contracts list both: NAICS to define business size standards, and PSC to describe the work. Understanding both helps you find the right opportunities.

The General Services Administration (GSA) maintains and periodically updates PSC codes to reflect new technologies, products, and services. Codes can be added, retired, or modified. Always check that you're using active PSC codes when registering in SAM.gov or responding to opportunities. Inactive codes may still appear on older contracts.
