The Hidden Power of NAICS Codes: And How They Shape Your Small Business Federal Strategy
If you’ve ever wondered why you're not showing up in SAM.gov searches, or why your bids are falling flat, it might come down to three unassuming numbers: your NAICS codes. Choosing and managing them correctly isn’t just a compliance issue. It’s a visibility and opportunity engine. And in 2025, with new SBA size standards and NAICS changes in motion, it's more important than ever to get this right.
The North American Industry Classification System (NAICS) is how the federal government categorizes business activities. When agencies issue solicitations, they assign a single NAICS code to each contract. This determines both who qualifies as a small business and what kind of vendors show up in market research.
The SBA also uses your primary NAICS when evaluating applications for programs like 8(a) certification assistance, women owned small business certification, or disabled veteran small business certification. But here’s the kicker: the primary NAICS doesn’t control what you can bid on. Your eligibility is based on the NAICS in the solicitation, not the one you list first in SAM.gov.
And as your business evolves, failing to update or expand your NAICS codes can seriously limit your search visibility, set-aside eligibility, and credibility with primes and agency buyers.
Why It Matters:
Here’s what’s at stake if you get your NAICS codes wrong or just ignore them:
You could be missing set-aside opportunities that fall under a NAICS you never added.
You might not show up in DSBS or SAM.gov searches done by agency small business specialists or primes.
You may misrepresent your qualifications, which can trigger protests or non-responsiveness in proposals.
You could get boxed out of SBA programs, like SBA 8a certification, if you’re no longer small under your primary NAICS.
You might be limiting growth runway as some NAICS codes have higher size standards than others, which can extend your time as a “small business” in the eyes of the federal government.
It’s not just about adding more codes, it’s about adding the right codes, for the right reasons, and updating them when your business pivots.
Here’s how to use NAICS codes as a strategic lever, not just a formality:
Match to your actual offerings. Use the NAICS Manual (or a trusted advisor) to choose codes that accurately reflect what you sell, not what you wish you sold.
Designate your primary NAICS intentionally. It should reflect your dominant revenue stream or strategic growth area—especially if you’re pursuing SBA 8a certification or other federal contracting certifications.
Add new NAICS codes when you have evidence. That includes:
Winning or pursuing contracts under a new NAICS
Shifting revenue streams
Adding a new SIN on your GSA Schedule
Launching a new business line
Monitor your size status across all codes. You can be small in one NAICS and large in another. Don’t assume you’re always “small.”
Use FPDS and USAspending.gov to validate which NAICS are actually being used by your target agencies. Don’t waste effort chasing codes with no action.
Align NAICS with your capability statement, DSBS profile, website SEO, and SBA certifications. Disconnected messaging = missed opportunity.
Bonus tip: If you're reselling products, make sure you're using the manufacturing NAICS code for compliance with the Nonmanufacturer Rule, not a wholesale or retail code that agencies won't use in solicitations.
Big Picture / Final Thoughts:
NAICS codes are more than administrative checkboxes, they’re strategic positioning tools. Done right, they help you get found, qualify for the right opportunities, and stay small business eligible longer. Done wrong, they can quietly sink your pipeline.
So take the time this quarter to do a NAICS health check. Clean up your SAM profile. Revisit your capability statement. And make sure your size status still holds up under every NAICS you list.
You’re not stuck with the NAICS codes you started with, but you are stuck with the consequences if you let them get stale.
