NAICS Codes Matter More Than Most Contractors Realize
When companies prepare their GSA Schedule offer, NAICS code selection is often treated as an afterthought — something you pick quickly and move on from. That's a mistake. Your NAICS codes determine your small business size standard, affect which set-aside opportunities you're eligible for, and signal to government buyers what kind of company you are.
As a former Contracting Officer, I used NAICS codes as a filter when searching for contractors. If your codes didn't match the work I was buying, you didn't show up in my search. It's that simple.
What Are NAICS Codes and Why Do They Matter?
The North American Industry Classification System (NAICS) is the standard used by federal agencies to classify businesses by industry. Every GSA Schedule offer requires you to identify your primary NAICS code and any additional codes that describe your business activities.
Here's why they matter for your GSA Schedule:
- Size Standard Determination — Each NAICS code has an associated small business size standard (based on revenue or employee count). Your primary NAICS code determines whether you qualify as a small business for your GSA Schedule. Choose the wrong code and you might lose your small business status.
- SIN Alignment — Your NAICS codes should align with the Special Item Numbers (SINs) on your GSA Schedule. If there's a disconnect between your NAICS codes and your SINs, it raises questions about whether you're actually qualified to perform the work.
- Searchability — Government buyers use NAICS codes to find contractors on GSA Advantage and eBuy. If your codes don't match the type of work they're buying, you won't appear in their searches.
- Set-Aside Eligibility — Many federal contracts are set aside for small businesses under specific NAICS codes. Your code selection directly impacts which set-aside opportunities you can compete for.
How to Choose the Right NAICS Codes
- Start with Your Core Revenue — Your primary NAICS code should reflect where the majority of your revenue comes from. Don't pick a code because it has a higher size standard — pick the one that accurately represents your primary business activity.
- Map Codes to Your SINs — For each SIN you're pursuing on your GSA Schedule, identify which NAICS codes best describe the products or services under that SIN. This ensures alignment between your offer and your industry classification.
- Check Size Standards Carefully — Review the size standard for each NAICS code at SBA.gov. Make sure you qualify as small under the codes you select if small business status is important to your strategy.
- Use Multiple Codes When Appropriate — If your company operates across multiple industries, you can list additional NAICS codes beyond your primary one. This increases your visibility to buyers searching by different codes.
- Review the 2022 NAICS Updates — NAICS codes are updated every five years. The 2022 revision added new codes and modified existing ones, particularly in technology-related industries. Make sure you're using current codes, not outdated ones.
Common NAICS Mistakes on GSA Offers
- Gaming the Size Standard — Selecting a NAICS code primarily because it has a higher size standard (so you qualify as small) rather than because it accurately describes your business. This can backfire during audits or size protests.
- Using Outdated Codes — Submitting your GSA offer with NAICS codes from a previous revision. Always verify you're using the current NAICS edition.
- Misalignment with SINs — Listing NAICS codes that don't logically connect to the SINs you're offering. This creates confusion for evaluators and can slow down your offer processing.
- Not Updating After Business Changes — If your company's primary business activity has shifted over time, your NAICS code should reflect that. Update your SAM.gov registration and your GSA contract accordingly.
The Bottom Line
NAICS codes are a foundational element of your federal contracting identity. Get them right, and you'll show up in the right searches, qualify for the right set-asides, and maintain a clean compliance profile. Get them wrong, and you'll miss opportunities you didn't even know existed.
