If the affirmation letter will not meet your needs and you wish to obtain a copy of the original determination letter, you must send a written request to the EO Determinations office in Cincinnati. The request should be submitted 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. Securing a copy of the original determination letter to send to you may take up to 60 days or longer.
