Any organization currently authorized to mail at the Nonprofit Standard Mail rates at one post office may obtain authorization to mail at those rates at an additional mailing office (described in Domestic Mail Manual (DMM) E670.8.0). Additional authorizations will be granted only to the organization holding the original authorization. A national organization may not obtain an additional mailing office authorization for mailings of its independent chapters.
