Your NAICS codes are how the federal government finds you — and how you find federal opportunities. Pick the wrong ones and you'll waste years bidding on contracts you'll never win. Pick the right ones and the system starts working for you.
Stop Picking NAICS Codes Like You're Building a LinkedIn Profile
Most contractors pick NAICS codes that describe what they do. That's wrong. You should pick codes that match what agencies are actually buying in your space.
Example: a small IT services firm might list 541511 (Custom Programming), 541512 (Systems Design), and 541519 (Other Computer Services). Sounds reasonable. But agencies in their target market may issue 80% of relevant work under 541330 (Engineering Services) or 541611 (Management Consulting) because of how their procurement office classifies the work.
3 Steps to Find Your Money-Making NAICS Codes
- Pull award history for your top 3 services. In GovSeeker, search recent awards by keyword and look at the NAICS column. Note the top 5 codes.
- Check the size standard. Each NAICS has a small business size standard (revenue or headcount). A code where you're "small" gets you set-aside access; one where you're "large" doesn't. Pick codes where you qualify.
- Look at competition density. Some NAICS have 50+ qualified small businesses on every solicitation. Others have 5. The thinner the field, the better your odds.
Primary vs. Secondary Codes
You can register up to 5 NAICS codes on SAM.gov, but only one is "primary." The primary code matters for SBA programs, size determinations, and small-business reporting. Choose carefully.
Don't Forget PSC Codes
Product Service Codes (PSCs) are a parallel classification system. Many agencies search PSC first, NAICS second. If you're invisible in PSC, you're missing half the opportunities.
Re-evaluate Annually
Agency buying patterns shift. Codes that were quiet two years ago may be hot now. Run the analysis above every year — GovSeeker's NAICS Optimizer tool does it automatically based on your capability statement.
