NAICS codes considerably impact federal bidding eligibility by determining which contracts a business can pursue. Contracting officers assign these codes to solicitations based on the primary purpose of goods or services required. Businesses must register appropriate NAICS codes in SAM.gov to become visible to government buyers seeking specific products or services. Inaccurate codes can disqualify companies from opportunities, while strategic selection of multiple codes can maximize contract eligibility. Proper management of these classifications enhances competitive positioning in the federal marketplace.
Understanding the Critical Role of NAICS Codes in Federal Procurement

Steering through the federal procurement landscape requires businesses to master the North American Industry Classification System (NAICS) codes, which serve as gatekeepers to government contract opportunities.
The NAICS code significance extends beyond simple categorization, determining whether a business qualifies for specific contracts based on industry and size standards. While companies may have multiple NAICS codes to reflect their diverse operations, they must carefully select their primary classification for bidding purposes.
NAICS codes serve as critical qualification thresholds, not mere labels, in the competitive federal contracting arena.
Contract classification through NAICS codes enables contracting officers to match businesses with appropriate opportunities. When issuing solicitations, officers must assign the NAICS code that best represents the principal purpose of the goods or services being procured.
This system guarantees regulatory compliance while streamlining the procurement process by filtering eligible contractors. The Small Business Administration sets size standards for each NAICS code that determine small business eligibility for government contracts. For businesses seeking federal contracts, understanding their NAICS classification is essential for identifying suitable opportunities and meeting qualification requirements established by federal agencies. Companies must also ensure accurate NAICS code entry during the mandatory SAM.gov registration process to be visible to government buyers.
Strategies for Selecting and Updating Your Business NAICS Codes

Every successful federal contractor recognizes that strategic NAICS code selection directly impacts bidding opportunities and contract eligibility. When selecting appropriate codes, businesses should carefully review the U.S. NAICS Manual descriptions and determine which classifications best match their primary activities.
Business diversification strategies often necessitate multiple NAICS codes to fully represent expanded service offerings. Companies should regularly audit their registered codes, particularly following:
- Expansion into new markets
- Addition of new product lines
- Significant shifts in revenue distribution across services
NAICS code compliance requires staying current with periodic system updates issued by the government. When classifications change, contractors must promptly update their SAM.gov profiles to maintain eligibility for relevant solicitations. The system is reviewed every five years to reflect economic changes and emerging industries.
Inaccurate codes may disqualify otherwise competitive businesses from lucrative federal opportunities. Government agencies use NAICS codes to streamline procurement by matching their needs with qualified vendors in specific industry categories. Businesses should avoid selecting codes based on individual products alone and instead focus on primary business activities when determining their classifications.
Navigating Multi-Domain Contracts and Size Standards With NAICS Codes

Federal contractors working with multi-domain contracts face complex challenges when applying NAICS codes across varied business activities. Understanding size standards and managing NAICS classifications are vital components of successful multi-domain strategies in federal contracting. Federal procurement goals drive agencies to seek diverse suppliers through targeted NAICS code classifications.
- Business Size Qualification – Companies must verify they meet the SBA size standards for each NAICS code, which may vary between employee count (typically 500 for manufacturers) or annual revenue thresholds ($7.5 million for many non-manufacturers).
- Contract Eligibility Assessment – Different NAICS codes affect eligibility for set-aside programs like 8(a), SDVOSB, and WOSB.
- Code Customization – Businesses operating across industries should register multiple NAICS codes to maximize contract opportunities.
- Compliance Monitoring – Regular review of NAICS classifications guarantees continued eligibility as business operations evolve.
Frequently Asked Questions
Can a Subcontractor Use Different NAICS Codes Than the Prime Contractor?
Subcontractors can utilize different NAICS codes than their prime contractors on federal projects.
This flexibility allows subcontractors to operate under their own industry classifications, even when supporting contracts with different primary designations.
However, subcontractor classifications do not alter prime contractor requirements regarding subcontracting limitations set by the solicitation’s assigned NAICS code.
Both parties must adhere to compliance rules governing the percentage of work performed, regardless of the subcontractor’s industry classification, to maintain contract compliance and avoid potential penalties.
How Do NAICS Codes Affect Joint Venture Eligibility for Federal Contracts?
NAICS codes directly determine joint ventures’ eligibility for federal contracts.
Joint ventures must meet the size standard for the specific NAICS code assigned to the solicitation. All partners must qualify as small under that code, unless operating under approved exceptions like the SBA’s Mentor-Protégé Program.
The eligibility criteria require proper documentation of compliance with size standards and adherence to SBA regulations.
Joint ventures should carefully verify their qualification under the assigned NAICS code before submitting offers.
What Happens if a Business Outgrows Its NAICS Code Size Standard?
When a business outgrows its NAICS code size standard, several consequences occur immediately. The company loses eligibility for small business set-aside contracts in that NAICS category, though it may complete any current contracts already awarded.
Business growth beyond size standards forces companies to compete in full-and-open solicitations against larger competitors.
Businesses can adapt by exploring other NAICS codes with higher thresholds, forming joint ventures with qualifying small businesses, or diversifying their service offerings to qualify under different classifications.
Can Foreign-Owned Businesses Use NAICS Codes for Federal Contracting?
Yes, foreign-owned businesses can use NAICS codes for federal contracting if they meet specific requirements.
To qualify, they must have a physical location in the United States and contribute to the U.S. economy. NAICS code compliance requires these businesses to meet the same size standards as U.S.-owned companies.
Foreign entities must also adhere to federal acquisition regulations and provide documentation of their U.S. business operations during registration.
How Often Should Businesses Re-Evaluate Their NAICS Code Selections?
Businesses should re-evaluate their NAICS code selections at least once every five years to align with official NAICS code updates.
Additional reviews are recommended whenever significant industry changes occur, such as entering new markets or modifying service offerings.
Companies pursuing federal contracts should conduct annual reviews to guarantee their classifications remain accurate, as misclassification can affect eligibility for contracts and may result in compliance issues with federal regulations.
