EO Operational Requirements: Obtaining Copies of Exemption Determination Letter from IRS

How can I get a copy of my organization's exemption letter?

You may request an affirmation letter. The affirmation  letter serves the same purpose for grantors and contributors as the original determination letter.

To receive a copy of the original determination letter, submit a request using Form 4506-A , or in a letter containing the name and employer identification number of the organization, along with the name, address and phone number of the requester. You can send your request by fax to 855-204-6184 , or by mail to:

Internal Revenue Service
Attn: Correspondence Unit
P.O. Box 2508, Room 6-403
Cincinnati, OH 45201

It may take 60 days or longer to process your request.

If you have a subordinate organization under group exemption ruling, contact the central organization that holds the group ruling to obtain confirmation of their status as members of the group. See Publication 4573, Group Exemptions, for more information.
