    NAICS Code Lookup

    Master NAICS code lookup for government contracting. Learn how to identify your codes, comply with SBA size standards, and win more federal contracts.

    Glossary entryBrowse NAICS demand lanesBrowse PSC contract lanes

    Introduction

    In the complex world of federal procurement, precision is paramount. Before a small business can bid on a contract, it must identify its primary business activities using the North American Industry Classification System (NAICS). A NAICS code lookup is the foundational step in ensuring your firm qualifies for specific set-aside contracts and adheres to size standards established by the Small Business Administration (SBA). Mastering this process is essential for any contractor leveraging tools like SamSearch to identify relevant opportunities.

    Definition

    A NAICS code lookup is the process of identifying the specific six-digit numerical classification assigned to a business’s primary economic activities. The federal government uses these codes to collect, analyze, and publish statistical data related to the U.S. economy. In contracting, these codes are critical because the SBA assigns size standards—either in terms of average annual receipts or number of employees—to each NAICS code to determine if a firm qualifies as a "small business" for a specific solicitation.

    Why It Matters

    Under FAR Part 19, the government reserves certain contracts for small businesses. If your firm’s NAICS code does not align with the solicitation, you may be ineligible for the award or, conversely, you might be incorrectly classified, leading to compliance risks. Proper classification ensures you are competing against the right peer group and helps you target the correct Product Service Codes (PSCs) that often accompany NAICS-based solicitations.

    Examples

    • Construction: A firm specializing in commercial building construction would look up codes under the 236220 series. If they mistakenly use a code for residential construction (236118), they may find themselves ineligible for federal infrastructure projects.
    • IT Services: A cybersecurity firm might utilize NAICS 541512 (Computer Systems Design Services). If they perform specialized software development, they might also need to consider 541511 to capture a broader range of task orders.
    • Consulting: Management consulting firms often use 541611. By performing a thorough lookup, a contractor can verify if their revenue falls under the SBA’s current size standard for that specific code.

    Frequently Asked Questions

    1. How do I find the correct NAICS code for my business? The official source for a NAICS code lookup is the U.S. Census Bureau’s NAICS website. You should review the descriptions of each code to see which most accurately reflects your primary revenue-generating activities.

    2. Can I have more than one NAICS code? Yes. While you must designate one primary NAICS code in your System for Award Management (SAM.gov) profile, you can list multiple secondary codes if your business provides diverse services or products.

    3. Does the government decide my NAICS code? No. The contracting officer (CO) assigns the NAICS code to a specific solicitation based on the principal purpose of the requirement. However, you must ensure your SAM.gov profile includes the code the CO selects if you intend to bid.

    4. What happens if I disagree with the NAICS code in a solicitation? If you believe the NAICS code assigned to a solicitation is incorrect, you can file a formal NAICS code appeal with the SBA Office of Hearings and Appeals (OHA) before the bid submission deadline.

    Conclusion

    Performing an accurate NAICS code lookup is more than a bureaucratic requirement; it is a strategic business decision. By aligning your capabilities with the correct codes, you ensure your firm is visible to the right agencies and compliant with SBA size standards. Platforms like SamSearch simplify this by allowing you to filter opportunities by your specific NAICS codes, ensuring you never miss a solicitation that matches your core competencies.
