Since the 1990s, the Internal Revenue Service (IRS) has been using a modified version of the classification code system created by National Center for Charitable Statistics (NCCS) called the National Taxonomy of Exempt Entities – Core Codes (NTEE-CC).  The IRS specialists, who determine whether an organization is eligible to receive federal tax exempt status, use the NTEE-CC to classify the organizations based on information found in the organization’s application for recognition of tax-exempt status (Forms 1023 and 1024).  Below is the full list of NTEE-CC codes.
