MDLPMU is required as part of USPS Postal One the INF card MDLPMU is based on the Date and Method. The information required by MailStream Plus [MSP] is for the type of Move/Update procedure performed on the input file prior to MailStream Plus as part of a hygiene process to correct address information. Pitney Bowes offers two applications to correct address/ zipcode information [CODE 1 PLUS and FINALIST].
