Selecting ideal NAICS and PSC codes requires strategic analysis of primary revenue streams and core business activities. Companies should examine financial statements, workforce allocation, and historical contract data to identify appropriate classifications. Quarterly reviews of SAM profiles guarantee relevance and visibility to government buyers. Avoid outdated codes, overly broad categories, and misalignments with marketing materials. Successful contractors maintain consistency across government platforms and remove irrelevant codes to enhance credibility. The following strategies will transform your government contracting opportunities.
Strategic Approaches to Identifying Your Primary NAICS Code

Why do many businesses struggle with NAICS code selection during their SAM registration process? The challenge often stems from misunderstanding how the classification system works, leading companies to select codes that don’t accurately reflect their core business activities.
A strategic approach begins with primary revenue analysis, examining which services or products generate the most income. Business owners should review financial statements to identify their highest-earning categories, as these typically represent primary business functions. Remember that the six-digit numbers in the NAICS system represent increasingly specific industry classifications as you move from left to right.
Additionally, conducting a workforce focus assessment reveals how employee time and resources are allocated across departments, providing insight into operational priorities. The selection process directly impacts your visibility to contractors seeking specific industry capabilities. Proper NAICS code selection is essential since SAM registration is mandatory for all businesses seeking government contracts.
Effective NAICS code selection requires examining:
- Historical revenue streams by service category
- Department size and resource allocation
- Client contract data showing most frequent deliverables
- Marketing materials to verify alignment with promoted specialties
This methodical approach guarantees your primary NAICS code accurately represents your business’s core competencies.
Maximizing Opportunity Through Proper PSC Code Selection

Maneuvering the complex landscape of Product Service Codes (PSC) requires strategic planning and careful analysis to maximize federal contracting opportunities. Companies must understand the alphanumeric structure and hierarchical organization of these codes to guarantee proper matching with relevant contract opportunities.
Effective code validation includes reviewing past contracts on beta.SAM.gov and utilizing specialized search tools to identify commonly used codes in similar procurements. During the SAM.gov registration process and annual renewal, businesses must provide accurate NAICS and PSC codes to ensure proper classification. Regular PSC code updates are essential as the PSC Manual changes to reflect evolving government procurement needs. Industry classification plays a pivotal role in determining eligibility for specific government bidding opportunities.
Businesses should avoid common selection pitfalls such as:
- Using outdated codes from pre-2024 PSC manuals
- Overlooking agency-specific preferences for certain codes
- Selecting overly broad categories when more specific options exist
- Mismatching deliverables with inappropriate service categories
The most successful contractors employ cross-code strategies, pairing complementary NAICS and PSC codes to signal specialization while avoiding overextension into non-core areas.
This strategic approach guarantees visibility in micro-purchases and enhances positioning for set-aside contracts targeting specific socioeconomic programs.
Best Practices for Managing NAICS and PSC Codes in Your SAM Profile

Maintaining an effective SAM profile requires strategic management of NAICS and PSC codes to maximize federal contracting opportunities for businesses of all sizes.
Regular code updates guarantee businesses remain visible to government buyers as operations evolve and market conditions change.
Evolving businesses require evolving SAM profiles—regular code updates ensure continuous visibility in the dynamic federal marketplace.
Organizations should implement quarterly reviews of their SAM profile to verify code alignment with current business capabilities. This proactive approach prevents missed opportunities due to outdated classifications.
When updating codes, businesses should:
- Assess recent contract awards within target agencies
- Compare current capabilities against selected codes
- Remove irrelevant codes that dilute market focus
- Add emerging service areas as operations expand
Consistency across all government platforms enhances credibility and search visibility.
Small businesses must carefully consider size standards when selecting NAICS codes as these directly impact contract eligibility and qualification for set-aside opportunities.
Properly aligned NAICS and PSC codes serve as powerful tools for targeted market research and competitive positioning, helping businesses identify suitable contract opportunities before they’re published publicly.

Frequently Asked Questions
Can I Change My NAICS Codes After Initial SAM Registration?
Yes, organizations can change their NAICS codes after initial SAM registration.
This process is managed through the SAM.gov “Manage Entity” portal, specifically in the Core Data section. Businesses should navigate to the NAICS/PSC tab to add, remove, or modify codes that reflect current capabilities.
After changing codes, updates typically appear in the system within 1-2 business days. Companies should allow at least 48 hours before bid submissions to guarantee the modified codes are active in the system.
How Many NAICS and PSC Codes Should I Include?
Businesses should include one primary NAICS code that best represents their main activity, plus additional codes that accurately reflect their capabilities.
NAICS selection strategies suggest including 5-10 relevant codes, avoiding overextension.
For PSC code importance, companies should select 3-7 codes that precisely match their service offerings.
Quality matters more than quantity – each code should genuinely represent services the business can deliver competently, as misrepresentation could lead to contract ineligibility or performance issues.
Do NAICS Code Size Standards Affect Contract Eligibility?
NAICS code size standards directly determine contract eligibility.
Businesses exceeding the applicable size standard, whether based on revenue or employee count, cannot qualify for small business set-aside contracts under that classification.
The standard in effect at solicitation issuance governs eligibility unless amended before the offer due date.
Contracting officers must assign codes that match the principal purpose of procurement, impacting which businesses can compete for the opportunity.
What Happens if I Select Incorrect Codes?
Selecting incorrect NAICS or PSC codes carries significant implications for government contractors.
Code selection consequences include potential debarment from federal contracting, legal penalties for misrepresentation, and contract termination.
Incorrect code implications extend to missed opportunities, as businesses become ineligible for relevant solicitations and set-aside contracts.
Additionally, organizations face administrative burdens like registration delays, compliance checks, and time-consuming appeals processes to rectify errors in their SAM.gov profile.
Are Certain NAICS Codes More Competitive for Government Contracts?
Yes, certain NAICS codes are considerably more competitive for government contracts.
Competitive industries like IT services and construction typically see numerous bidders per solicitation.
Meanwhile, specialized sectors such as healthcare services and niche real estate often have minimal competition, averaging just 1-2 bidders.
Effective code selection strategies include targeting these lower-competition codes where a company has expertise, balancing opportunity volume with competitive advantage.
