How this finder works
The finder searches the code-and-title list in the January 2025 IRS Form 1023-EZ instructions. Each result identifies the official IRS code and title, a separately labeled Easy5013c explanation, and editorial search terms used to connect everyday descriptions with possible codes.
Matching considers your primary activity, optional major-group and editorial purpose-family filters, and organizational function. You may see several candidates when more than one code could describe the activity.
What the results mean
Use each result as a comparison aid, not as an IRS determination or guaranteed answer. Review the official title, editorial explanation, and neighboring codes against what your organization will actually do.
NCCS describes NTEE as a descriptive taxonomy and cautions that one category may not capture every activity. Read additional NTEE context from NCCS.
Your NTEE code, activity description, and exempt purposes are separate
Form 1023-EZ treats these as related but separate entries:
- Your mission or most significant activities describe what the organization plans to do.
- Your NTEE code generally summarizes the organization’s purpose in three characters.
- Your section 501(c)(3) exempt-purpose selections identify the applicable purpose categories on the form.
An NTEE code is not a substitute for the activity description, and it is not itself an exempt-purpose selection. Review the current Form 1023-EZ instructions.
NTEE codes are not historical IRS Activity Codes
Historical IRS Activity Codes are a separate, older system that is no longer updated. The current Form 1023-EZ entry is an NTEE code selected from the list in the form’s instructions. This finder does not offer historical activity codes as filing choices. See IRS Publication 4838.
How to compare neighboring codes
Easy5013c editorial guidance: Start with the organization’s real primary activity—not every program it might eventually offer. Compare the official titles of nearby candidates, then ask which one most directly describes the organization’s central actual or planned work. This is a comparison method, not an IRS rule based on activity size or program volume.
If two codes remain plausible, keep both in the comparison view. It will show the distinctions to consider while preserving uncertainty instead of forcing a single answer.
D20 — Animal Protection & Welfare
Easy5013c editorial comparison: D20 may be the closer candidate when protecting animal welfare is the organization’s central purpose.
D60 — Animal Services N.E.C.
Easy5013c editorial comparison: D60 may deserve comparison when the primary work is another kind of animal service not captured by a more specific title.
Review the organization’s actual main activity and neighboring titles before choosing. These explanations are editorial and do not replace the official IRS titles.
What if your organization spans several categories?
NCCS describes NTEE as descriptive rather than prescriptive and cautions that one category may not capture every activity. It also says an NTEE category is not an official designation restricting nonprofit activities. Read the NCCS NTEE context.
Easy5013c editorial guidance: Focus first on the organization’s central actual or planned work, then compare the strongest alternatives. If the balance is unclear, use the comparison summary to record why each candidate might fit and review the choice before filing.
When a code needs closer review
Not every code listed in the Form 1023-EZ instructions necessarily describes a section 501(c)(3) purpose. Some selections may require closer review alongside the organization’s mission or activity description. A code alone does not establish Form 1023-EZ eligibility.
The finder checks a confirmed selection against the current Form 1023-EZ list. If the code is no longer available, you will be asked to choose again. Read the IRS processing procedures or check Form 1023-EZ eligibility.
Review, then confirm your code
After comparing candidates, choose Review this candidate. The review summary keeps the official title separate from the editorial rationale, lists any alternatives you compared, and gives you a focused print copy. Nothing is saved during this first step.
Only the final Confirm this NTEE code and continue filing action carries the code into the guided filing. When you first reach Activities, the carried code is identified for review; after that review, it behaves like any code you enter or change manually. Search text and comparison details are never carried into the filing.

What if several NTEE codes seem to fit?
Compare the candidates against the organization’s real primary activity and review neighboring official titles. One category may not capture every activity, so you do not need to force a match before comparing the alternatives. NCCS NTEE context
Does choosing an NTEE code prove that my organization qualifies for 501(c)(3) status or Form 1023-EZ?
No. The NTEE code is one entry on the application and does not determine eligibility. Check Form 1023-EZ eligibility
Does the full Form 1023 also ask for an NTEE code?
Yes. The full Form 1023 also requests a three-character NTEE code and directs applicants to its Appendix D list. Form 1023 instructions
Why might I need to choose my code again?
If your confirmed code is not available in the current Form 1023-EZ list when you continue, you will be asked to search and choose again. A code absent from the current instructions may be treated as invalid during IRS processing. IRS processing procedures

This finder provides comparison and filing-preparation information, not legal or tax advice. Results are candidates for your review and are not IRS approval or a guarantee that a code is correct, that the organization qualifies under section 501(c)(3), or that it is eligible to file Form 1023-EZ.
