Abstract: A special service mailpiece having an integral document section and a method for forming the mailpiece requiring special services are provided. The mailpiece has an integral document section requiring special service mailing and includes a sheet folded into sections along a fold line, then sealed to enclose the integral document section. The sheet further has a removably attached section which, after the system is folded and sealed, forms a return postcard and at least one form. The return postcard and the form are integrally formed, but removably attached, such that the return postcard remains attached to the mailpiece until received by the addressee at which time it may be removed.
