The National Taxonomy of Exempt Entities (NTEE) system was developed by the National Center for Charitable Statistics (NCCS) and is used by the Internal Revenue Service (IRS) and NCCS to classify tax-exempt organizations.

How Do NTEE Codes Get Assigned?

A specialist from the IRS assigns an NTEE code to each organization exempt under I.R.C. § 501(a) as part of the process of closing a case when the organization is recognized as tax-exempt. For more information and more detailed definitions of these codes developed by the National Center for Charitable Statistics (NCCS), visit the Urban Institute.

A Comprehensive View of an Organization’s NTEE Code

The National Taxonomy of Exempt Entities (NTEE) system was developed by the National Center for Charitable Statistics (NCCS) and is used by the Internal Revenue Service (IRS) and NCCS to classify tax-exempt organizations. A specialist from the IRS assigns an NTEE code to each organization exempt under I.R.C. § 501(a) as part of the process of closing a case when the organization is recognized as tax-exempt. For more information and more detailed definitions of these codes developed by the National Center for Charitable Statistics (NCCS), visit the Urban Institute.

The code may be adjusted later on by the IRS to better reflect the nature of the mission of the organization. Many private organizations and foundations rely on the NTEE code to approve grants, but in close to 33% of cases, there are significant discrepancies between the code reported by the IRS, the one reported by the NCCS, and the one inferred from the mission statement of the organization.

We offer visibility of the code reported by two different sources:
  1. NTEE reported by the IRS, updated monthly.
  2. NTEE reported by the NCCS, updated annually.

As well as the category the organization falls under based on the automated analysis of the organization’s mission statement and impact areas as reported in the organization’s filing with the IRS, updated monthly.

What is an EIN Number?

Each organization has a distinct EIN number provided by the Internal Revenue Service. EIN stands for Employer Identification Number and is also known as the Federal Employer Identification Number or the Federal Tax Identification Number. This is a unique nine-digit number assigned by the IRS to business entities operating in the United States for the purposes of identification. Both for-profit and nonprofit organizations have IRS EIN numbers.

UN SDG Classification and NTEE Updates

The UN Sustainable Development Goals provide a common framework for organizing funding, partnerships, and support for the millions of organizations working on key issues like poverty alleviation and climate change. We have classified organizations under the UN SDGs based on how their mission, impact statements, website content, and other information reported to the IRS aligns with the 169 Targets and 231 Indicators defined by the UN.

The NTEE code might be adjusted by the IRS to better reflect the nature of the mission of the organization. The IRS publishes an updated table of the NTEE codes by EIN periodically and we update our database weekly. If you think that your NTEE code needs to be adjusted with the IRS, follow these guidelines from the IRS.

How are UN SDG Classification and NTEE Codes Used?

Using NTEE codes and the UN SDG taxonomy helps capital sources, donors, foundations, and impact investors inform social impact funding strategies. Thanks to our X4Impact Founding Partners, we offer this free tool to simplify your EIN search, NTEE code lookup, and understanding of an organization’s alignment with the Sustainable Development Goals. We process over one million IRS records monthly to keep this tool updated.
