Most new contractors learn about NAICS codes early, because the SBA uses them to set size standards and solicitations list one for every requirement. Fewer learn about the other classification system that appears on nearly every federal notice and award record: the Product Service Code, or PSC. Understanding both makes your market research sharper and your opportunity searches more precise.
Two systems, two purposes
NAICS codes describe industries. They were built for economic statistics across North America and classify businesses by what they primarily do. Product Service Codes describe purchases. They were built for federal procurement reporting and classify what the government bought, not who sold it. A contracting officer assigns one NAICS code to a solicitation to set the size standard, and one PSC to describe the product or service being acquired.
Because the two systems answer different questions, they do not map neatly onto each other. A single NAICS code for engineering services, for instance, might correspond to several PSCs depending on whether the work is a study, a design or on-site technical support.
How to read a PSC
A PSC is a four-character code. The first character tells you the broad type of purchase:
- Codes that begin with a letter describe services. Codes beginning with R cover professional, administrative and management support services; D covers information technology and telecommunications; J covers maintenance and repair of equipment; Y covers construction of structures and facilities; Z covers maintenance, repair or alteration of real property; and U covers education and training.
- Codes that begin with a number describe products, using the Federal Supply Classification groups. Group 70, for instance, covers computer equipment, software and related supplies, and group 75 covers office supplies.
The remaining characters narrow the category. The full list is published in the PSC Manual, which is maintained for the federal procurement data system and available through acquisition.gov.
Why contractors should care
PSCs show up in three places that matter to business development. First, opportunity notices on SAM.gov carry a PSC, so saved searches that combine your NAICS codes with your PSCs catch requirements that a NAICS-only search misses. Second, award records in the federal procurement data system and on USAspending.gov are tagged by PSC, which lets you see exactly which agencies buy a given type of service and how much. Third, many agency procurement forecasts list planned purchases by PSC rather than NAICS.
A short list of the PSCs that best describe your offerings belongs in your capability statement right beside your NAICS codes. It tells a buyer, in the government’s own vocabulary, what you sell.
Choosing the right codes
Start by looking up past awards for work like yours and noting the PSCs the government used. Patterns emerge quickly; agencies tend to classify similar work the same way. Then pick the handful of codes that cover most of what you do. As with NAICS codes, a focused list is more useful than a long one, both for searching and for describing your firm.
One caution
PSCs do not affect your size status or eligibility for set-asides; that is the role of the NAICS code on the solicitation. Treat the PSC as a research and search tool. Used that way, it closes a gap that many firms do not realize is there.
