3-3 Mailing After Authorization

3-3.1 Mailing Frequency and Revocation for Nonuse

The organization must make at least one mailing at the Nonprofit Standard Mail rates during a 2-year period or the authorization to mail at the nonprofit rates will be automatically revoked for nonuse. A primary authorization (the authorization obtained by filing PS Form 3624) will not be revoked for nonuse if one or more nonprofit mailings have been made during the 2-year period at the primary authorization Post Office or at an additional mailing office where authorization is based upon the primary authorization. An additional mailing office authorization, if no mailings at the Nonprofit Standard Mail rates have been made under that authorization during a 2-year period, will be revoked for nonuse. The PCSC notifies the organization of the revocation for nonuse whether the entry is a primary or an additional office authorization.

3-3.2 Changing Mailing Locations

If the organization wishes to change its primary office of mailing, the organization must submit a new application on PS Form 3624 to the Post Office intended to be the new primary office of mailing. The organization should attach to the PS Form 3624 all of the supporting documentation described in 3-1.

If the organization changes printers or mailing agents and requires a new additional mailing office authorization, follow the procedures in 3-2 to obtain the authorization. The organization may not transfer its authorizations between Post Offices.
