3-1.3 General Documentation Requirements

Organizations other than qualified political committees and voting registration officials must attach copies of the following documents to the PS Form 3624 to support the organization’s eligibility for nonprofit prices:

Formative papers. Formative papers describe the organization’s primary purpose. These papers include articles of incorporation, constitution, trust indenture, charter endorsed by appropriate civil authorities enabling legislation, or other organizing instrument.
Evidence of nonprofit status. Evidence of the organization’s nonprofit status may be a copy of the tax exemption letter from the Internal Revenue Service. This letter shows the organization’s exemption from the payment of federal income tax and cites the section of the Internal Revenue Code under which the organization is exempt — e.g., 26 U.S.C. 501(c)(3).

Alternatively, provide a complete financial statement from an independent auditor — such as a certified public accountant — substantiating that the organization is a nonprofit organization. Statements from officers of the applicant organization, internal financial statements, or other internal documents are not sufficient.
