While a Periodicals application is pending, the Postal Service keeps a record of all deposits and mailings prepared as Periodicals mail and for which postage is paid by advance deposit account. The price of postage for a Periodicals publication pending authorization is calculated by applying the applicable percent in DMM Exhibit 207.5.2.3 to PS Form 3541, Part P, Line P-1.
If the postage for a Pending Periodicals PS 3541 is paid using an Enterprise Payment System (EPS) account, the Periodicals price is charged. In the event the application is denied, an invoice would be generated for the applicable USPS Marketing Mail or other postage rate.
Publishers may be eligible for a refund of the difference, if any, between the postage paid and the applicable Periodicals postage for copies mailed while the application was pending. Until the Postal Service takes final action on your application, the applicable USPS Marketing Mail or Package Services
prices must be paid.
Note: The Postal Service does not keep a record of postage paid at First-Class Mail prices or of postage not paid by advance deposit account.
