NTEE/IRS Activity Codes

When an organization applies for tax-exemption with the IRS, it selects a code or codes to reflect its purposes, activities, operations or type.  These codes act as an organization's 'keywords'.

There are Actually two sets of codes currently in use  by the IRS: the IRS Activity Codes and the National Taxonomy of Exempt Entity coding, or NTEE.  The NTEE codes went into effect in January, 1995.  Therefore organizations which had registered with the IRS prior to January 1995, maintain their Activity Codes, while all organizations receiving exempt status since that time use the NTEE.
