What must a mailer present to apply for a mailing permit?

To apply for a mailing permit, a mailer must present PS Form 3615, which is specifically designated for this purpose. This form is essential because it collects the necessary information and authorizations required by the postal service to verify the mailer's eligibility and establish the transaction for mailing services. The form typically includes important details such as the name and address of the mailer, the type of mailing intended, and agreement to adhere to postal regulations.

Other forms mentioned, while important in the mailing process, do not serve the same function for applying for a mailing permit. For instance, PS Form 3600 FCM is used for bulk mailings and requires different information relevant to postage payment, while PS Form 3602 N is intended for specific mailing arrangements rather than the permit application. PS Form 3617 is used for reporting changes or updates regarding mailing permits or postage payment systems. Each form has its specific role, making PS Form 3615 the correct choice for permit applications.
