Choosing a NAICS code may sound like a dry administrative task, but for nonprofit organizations it can affect how funders, government agencies, lenders, researchers, and vendors understand what you do. A correctly selected code helps classify your organization in the broader economy, making it easier to compare your nonprofit with similar groups and complete forms accurately.
TLDR: A NAICS code is a numerical classification that identifies an organization’s primary economic activity. Nonprofits do not have one universal NAICS code; instead, they choose the code that best matches their main mission or service. Many nonprofits fall under sector 813, Religious, Grantmaking, Civic, Professional, and Similar Organizations, but others may use codes for health care, education, social assistance, arts, or housing. The best code is the one that describes what your organization actually does most of the time.
What Is a NAICS Code?
NAICS stands for the North American Industry Classification System. It is used in the United States, Canada, and Mexico to categorize businesses and organizations by industry. Each NAICS code is usually six digits long, with broader categories at the beginning and more specific activities reflected in the later digits.
For example, the broad sector 62 refers to Health Care and Social Assistance, while a more specific code under that sector may identify mental health services, child day care, or community food programs. Government agencies use NAICS codes for statistics, tax administration, procurement, grant eligibility, and economic reporting.
Although the system is often associated with businesses, nonprofit organizations also use NAICS codes. The key point is that NAICS does not classify an entity based on whether it is nonprofit or for-profit. It classifies the organization based on its primary activity.
Is There One NAICS Code for All Nonprofits?
No. There is no single NAICS code that covers every nonprofit organization. A food bank, university, animal shelter, church, museum, medical clinic, and environmental advocacy group may all be nonprofits, but they perform very different activities. As a result, they can fall under different NAICS categories.
That said, many nonprofits are commonly classified under NAICS sector 813, which is titled Religious, Grantmaking, Civic, Professional, and Similar Organizations. This sector includes organizations that promote specific causes, provide membership services, make grants, or support community, civic, religious, and social missions.
However, sector 813 is not always the right answer. If a nonprofit primarily operates a hospital, its code may belong in health care. If it runs a school, the education sector may be more accurate. If it provides housing, social assistance, or performing arts programming, another code may fit better.
Common NAICS Codes Used by Nonprofit Organizations
Below are some of the most common NAICS categories nonprofits may encounter. These are examples, not a substitute for reviewing the official definitions carefully.
- 813110 Religious Organizations: Churches, synagogues, mosques, temples, and other religious institutions.
- 813211 Grantmaking Foundations: Private foundations and charitable trusts that primarily award grants.
- 813212 Voluntary Health Organizations: Groups focused on disease awareness, health research support, and patient advocacy.

How to Choose the Right NAICS Code
The most important rule is simple: choose the code that reflects your organization’s primary activity. In other words, ask, “What does our nonprofit mainly do?” Not what you hope to do someday, not every service you occasionally provide, but the core activity that best represents your mission in practice.
For a nonprofit with several programs, this can be tricky. Imagine an organization that offers youth mentoring, after-school tutoring, free meals, and family counseling. Which code should it use? The answer depends on which activity is central to the organization’s operations, budget, staff time, and public identity.
Consider these practical questions:
- Where does most of your funding go? Your largest program may point to the correct classification.
- What service do people primarily associate with your organization? Public-facing identity matters.
- What activity takes the most staff or volunteer time? Time allocation can reveal the dominant function.
- What do your founding documents describe as your main purpose? Articles of incorporation and bylaws may help.
- What would a funder or government agency expect you to be classified as? Consistency can prevent confusion.
Why NAICS Codes Matter for Nonprofits
For many nonprofits, NAICS codes appear in situations such as grant applications, state registrations, federal forms, business bank account paperwork, loan applications, and vendor onboarding forms. They may also be used when applying for government contracts or participating in research surveys.
A NAICS code can influence how your nonprofit is grouped in databases. That may sound minor, but classification affects visibility. A nonprofit listed under environmental advocacy may show up in different searches, reports, or funding reviews than one classified under civic organizations or educational services.
In some cases, eligibility rules for programs or contracts may reference NAICS codes. For example, certain government opportunities are limited to organizations within specific industries. If your code is inaccurate, you may miss an opportunity or face delays while clarifying your status.
NAICS codes can also help nonprofits benchmark themselves. If your organization is compared with similar organizations in the same classification, the data may be more meaningful for fundraising, strategic planning, and impact measurement.
NAICS Codes vs. IRS Nonprofit Classification
One common source of confusion is the difference between a NAICS code and an IRS nonprofit category. The IRS may recognize an organization as a 501(c)(3), 501(c)(4), 501(c)(6), or another tax-exempt type. That designation describes the organization’s tax status and legal purpose.
A NAICS code, by contrast, describes the organization’s economic activity. Two organizations can both be 501(c)(3) charities but have completely different NAICS codes. A nonprofit hospital, a scholarship foundation, and a ballet company may share tax-exempt status while belonging to different industry classifications.
Think of it this way: the IRS category answers, “What kind of tax-exempt organization are you?” The NAICS code answers, “What kind of work do you do?”
Can a Nonprofit Have More Than One NAICS Code?
In many forms, you will be asked for one primary NAICS code. However, an organization may have secondary activities that could be described by other codes. A nonprofit museum might also operate a gift shop, host educational programs, and run community events. Still, the primary code should usually represent the main activity, not an accessory program.
Some databases or registrations may allow multiple codes. When that option exists, list your primary activity first and add secondary codes only when they are meaningful and ongoing. Avoid adding codes simply to appear broader than you are; accuracy is more useful than ambition when it comes to classification.
Tips for Avoiding Common Mistakes
- Do not choose a code only because the word “nonprofit” seems implied. Focus on activity, not legal structure.
- Review official NAICS descriptions. Similar-sounding codes can have important differences.
- Update your code if your mission changes significantly. A nonprofit can evolve over time.
- Be consistent across important documents. Using different codes in different places can raise questions.
- Ask for professional guidance when needed. Accountants, attorneys, grant consultants, or state agencies may help interpret requirements.
Final Thoughts
The NAICS code for a nonprofit organization is more than a bureaucratic label. It is a compact way to describe your organization’s role in the economy and the community. While many nonprofits belong in the 813 sector, others are better classified under education, health care, social assistance, arts, housing, or another category.
The best approach is to choose the code that honestly reflects your nonprofit’s primary work. When your classification aligns with your mission, your paperwork becomes clearer, your data becomes more reliable, and your organization becomes easier for funders, partners, and agencies to understand.
