How can using Mail.dat improve Surface and Air Visibility?
In the future, Mail.dat will be used to provide greater Surface and Air Visibility. Using Mail.dat files, First-Class mailers may electronically exchange mailing information related to product visibility, including the PLANET Code/4CB, EDL (Enhanced/24 digit tray label), and MTEL (Mail Transport Equipment Label). This information, in some cases enhanced with PostalOne! Transportation Distribution and Routing (D&R) tags will ultimately provide end-to-end container visibility that includes surface and air transportation scans. As the USPS enhances these offerings, Mail.dat stands ready to support their expanded use by mailers.
