ToggleUnderstanding the Impact of NAICS Codes on Federal Contract Opportunities

Every federal contract opportunity hinges on the North American Industry Classification System (NAICS) codes that serve as the foundation for government procurement processes.
These codes determine contract eligibility across various industry classifications, creating strategic competitive advantages for properly registered businesses.
NAICS relevance extends beyond basic categorization, directly affecting participation in socio-economic programs like woman-owned or small business set-asides.
Government spending analysis reveals concentrated awards in specific sectors, with FY2023 data highlighting top-performing NAICS categories.
Set-aside contracts help create dedicated opportunities for small and disadvantaged businesses to compete effectively in federal procurement.
Even emerging technologies like AI and cybersecurity fall under broader NAICS classifications, requiring careful attention to procurement strategies.
The 2022 revision considerably expanded the landscape with 111 new industry codes, improving differentiation between IT subsectors and creating specialized opportunities in biotechnology and clean energy manufacturing.
Businesses can save time and resources by using NAICS codes to focus on finding matching contract opportunities that align with their capabilities.
The Professional, Scientific, and Technical Services sector, with NAICS codes beginning with 54, accounts for approximately 30% of awards in FY 2023, making it a significant area for government contracting opportunities.
Step-by-Step Guide to Updating NAICS Codes in Your SAM Registration

Updating NAICS codes in the System for Award Management (SAM) requires careful attention to detail and a systematic approach to guarantee accurate representation of business capabilities.
To begin the step-by-step process, log into your SAM.gov account and navigate to the Entity Registration section on the homepage.
Within the Core Data tab, locate the NAICS code field where you can add or modify your codes. Enter the new relevant codes that accurately reflect your business offerings, then save your changes.
It is ideal to maintain 5 to 15 relevant NAICS codes that properly represent your business capabilities.
Contracting officers thoroughly check NAICS codes on your SAM profile before awarding government contracts.
Selecting the right NAICS codes is crucial for federal marketplace visibility and matching with relevant contract opportunities.
Common mistakes include selecting incorrect codes or failing to verify updates after submission.
Always review your profile after updating to verify changes appear correctly. For best results, complete updates a day or two before submitting bids to verify your profile reflects current information.
Best Practices for NAICS Code Maintenance and Compliance

Maintaining accurate NAICS codes requires systematic attention to detail and regular review processes. Organizations should conduct thorough business activity analysis to guarantee their selected codes accurately reflect their primary operations, especially when bidding on government contracts.
Periodic review of NAICS classifications is essential as business activities evolve and industry standards change. Companies should verify that their codes comply with both federal and state regulations to avoid compliance issues. This verification process should occur at least annually or whenever significant operational changes occur. Understanding SBA size standards is crucial for determining small business eligibility and accessing federal contracting opportunities. Businesses should also be aware that NAICS codes revise every five years, making regular updates critical to maintaining accuracy.
When maintaining NAICS codes, organizations should:
- Document primary revenue-generating activities
- Compare operations against detailed code descriptions
- Consult industry experts when uncertain about classification
- Update SAM registration promptly when changes are necessary
Frequently Asked Questions
Can I Change My Primary NAICS Code Mid-Contract Performance?
Yes, a contractor can change their primary NAICS code during contract performance. However, this requires formal contract modifications to reflect the code relevance to actual work being performed.
The contractor must update their SAM.gov registration accordingly, which typically processes within 1-2 business days. Contracting officers must approve such changes, as they validate NAICS codes for eligibility requirements.
Maintaining accurate codes is essential for compliance with federal acquisition regulations and future contract opportunities.
How Many NAICS Codes Should a Typical Small Business List?
Following typical business practices, small businesses generally list 3-5 NAICS codes in their registrations.
Industry classification significance lies in proper representation of the company’s services and products. While one primary code is required based on the highest revenue-generating activity, additional relevant codes help businesses:
- Access more contracting opportunities
- Reflect their diversified operations
- Demonstrate their full range of capabilities
- Adapt to changing business focus
Small businesses should select codes that accurately represent their actual offerings.
Will Changing NAICS Codes Affect My Past Performance Ratings?
Changing NAICS codes does not directly alter existing past performance ratings. Past performance implications remain tied to the original NAICS code under which the work was performed.
However, NAICS code significance becomes apparent when bidding on new contracts, as evaluators assess whether past performance is relevant to the new industry category.
Businesses should understand that while their ratings stay intact, the perceived relevance of those ratings may shift when competing in different industry sectors.
Are There Penalties for Selecting Inappropriate NAICS Codes?
Yes, there are significant penalties for selecting inappropriate NAICS codes.
Businesses that misrepresent their NAICS code designation may face severe financial penalties under the False Claims Act.
NAICS code compliance is vital to maintain eligibility for federal contracts.
Improper code selection can result in legal action, debarment from government contracting, and damage to a company’s reputation.
The SBA actively monitors code usage to guarantee businesses operate within their proper industry classification.
Do Subcontractors Need to Match Prime Contractor NAICS Codes?
Subcontractors are not legally required to match prime contractor NAICS codes. Federal regulations, specifically FAR 19.102, mandate NAICS code assignments for prime contractors only.
Subcontractor requirements allow businesses to maintain their own appropriate NAICS codes in SAM based on their primary business activities.
While prime contractor alignment may be contractually required in specific situations, subcontractors generally operate under their own industry classifications.
They should confirm their SAM-listed NAICS codes accurately reflect their actual services to avoid misrepresentation.
