While your application is pending, the Postal Service keeps a record of your deposits and mailings that you prepare as Periodicals mail and for which you pay postage by advance deposit account. You 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, you must pay the applicable Standard Mail or Package Services prices. 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.
