To choose the right NAICS codes for nonprofits in SAM, first identify your organization’s primary activities and revenue sources. Start with sector 81 (typically 813 for nonprofits) and review detailed NAICS documentation to match your mission with specific 6-digit codes. Select codes representing the highest percentage of your activities, and include secondary codes if necessary. Accurate classification improves funding eligibility, supports regulatory compliance, and enhances visibility to government agencies. The following steps provide a structured approach for ideal code selection.

ToggleUnderstanding the Significance of NAICS Codes for Nonprofits

Clarity in classification forms the foundation of nonprofit success in today’s data-driven funding landscape. NAICS codes provide essential operational clarity by distinguishing nonprofit organizations from for-profit entities in federal databases, ensuring proper recognition of their unique status.
The importance of NAICS for nonprofit classification extends beyond identification. These codes directly impact funding eligibility by validating organizations for specific grant opportunities and government contracts. Federal agencies and foundations require these codes to match applicants with relevant funding programs.
NAICS codes open funding doors, serving as crucial validators that connect nonprofits with targeted grant opportunities and contracts.
Additionally, NAICS codes support regulatory compliance by linking organizational activities to specific tax exemptions. They enable sector benchmarking against similar nonprofits, providing valuable data for strategic planning and performance evaluation. These standardized codes reflect nonprofit organizations’ mission-oriented focus, emphasizing their dedication to societal benefits rather than profit generation. For social and civic organizations, NAICS codes capture their community engagement efforts that promote specific interests of their membership base.
Proper classification also streamlines administrative processes, reducing errors in proposal systems and government registrations. Selecting the correct NAICS code is particularly crucial when registering with SAM.gov, as it can qualify nonprofits for set-aside contracts designated for certain types of organizations.
Step-by-Step Guide to Selecting Your Primary NAICS Code

Maneuvering the NAICS code selection process requires methodical attention to organizational priorities and mission-focused analysis. Nonprofit leaders should begin by identifying their core service delivery model, not auxiliary activities like fundraising or administration.
First, determine your broad sector (typically 81 for nonprofits) and narrow to the appropriate subsector, such as 813 for religious, grantmaking, or civic organizations. Review the detailed descriptions in official NAICS documentation to guarantee proper nonprofit classification.
Next, cross-reference your mission statement with specific 6-digit codes like 813110 for religious organizations or 813212 for health advocacy groups. Verify selections using multiple government resources including Census Bureau tools and NAICS Association databases. Selecting the right code is essential for federal contract bidding and increasing your organization’s visibility to government agencies.
If your nonprofit engages in multiple revenue-generating activities, you may need to include secondary NAICS codes that reflect these additional streams.
When uncertain between multiple codes, select the classification representing the highest percentage of organizational activities. Remember that NAICS codes are self-assigned based on your nonprofit’s primary business activity, as there is no central agency that officially assigns or monitors these codes.
Aligning NAICS Codes With GSA Schedule Requirements

Most nonprofit organizations encounter significant complexity when aligning NAICS codes with General Services Administration (GSA) Schedule requirements.
Unlike standard procurements, GSA Schedule contracts require NAICS code alignment with predetermined Special Item Numbers (SINs), even when better-fitting codes exist for specific services.
GSA Schedule contracts demand alignment with SIN-associated NAICS codes, regardless of whether more suitable classifications exist.
When pursuing GSA opportunities, nonprofits must understand that contracting officers can only select NAICS codes pre-assigned to the Schedule, not necessarily those that best describe the work. This constraint affects NAICS code selection throughout the entire procurement process.
For OASIS+ contracts, nonprofits should note that Small Business (SB) contracts use the largest size standard within awarded domains, while Unrestricted (UR) contracts use the smallest.
Proper NAICS code alignment guarantees GSA contract compliance and prevents disqualification from bidding opportunities, making strategic code selection essential for success. Nonprofits should follow a step-by-step guide when identifying their primary business activities to match them with relevant codes. As illustrated in the Global Dynamics case, contracting officers lack discretion when selecting NAICS codes for task orders under GSA Schedule contracts. Remember that the GSA Schedule structure includes a total of 315 SINs for specific products and services that must be considered when determining appropriate NAICS codes.
Frequently Asked Questions

Do International Nonprofit Activities Require Special NAICS Consideration?
International nonprofit activities require special NAICS consideration due to their global operations. Organizations must navigate different compliance requirements across borders while selecting codes that accurately reflect their mission and activities in each jurisdiction.
Are Certain NAICS Codes More Favorable for Grant Applications?
NAICS codes don’t directly impact grant eligibility. However, they may align with certain funding priorities when they accurately reflect organizational activities. The focus should remain on program qualifications rather than code selection.
How Do NAICS Codes Affect Subcontracting Opportunities for Nonprofits?
NAICS codes determine subcontracting advantages by establishing which opportunities nonprofits qualify for. Code alignment between prime and subcontractors guarantees compliance with limitations on subcontracting rules and maximizes partnership eligibility for federal contracts.
