Understanding Postal: Get Smart

2. The “basic” option still requires the use of the IMB on all letters and flats — but with less stringent requirements. It doesn’t require electronic postage statements/documentation or the use of FAST. At a minimum, the IMB in the basic option must include the same delivery-point address code as in the POSTNET barcode today, as well as a Mailer ID, the class of mail and the Optional Endorsement Line if one is used on the mail piece — unless an adhesive barcode presort label is used. Catalogs using the basic option wouldn't receive free address correction services or mail-induction information.
