Automated USPS Returns
USPS has developed a new verification and payment method for Merchandise Returns Services (MRS) USPS and Scan Based Payment (SBP) customers, called automated USPS Returns. The current MRS process pose challenges such as reliance on sampling, lack of package-level pricing details, lack of visibility when a returned package travels through the mail stream, and packages held at postage due units before being returned to traditional verification customers. While SBP has limited capabilities for single-piece attribute-based pricing.
Bulk Parcel Return Service
Bulk parcel return service (BPRS) allows mailers of large quantities of Standard Mail machinable parcels that are either undeliverable-as-addressed or opened and remailed by addressees to be returned to designated postal facilities.
Bulk Proof of Delivery Program
The bulk proof of delivery program gives mailers the ability to receive signature proof of delivery records for applicable mailpieces without requesting them individually. This enhancement allows mailers to retain records longer than the Postal Service retention period and provides mailers a more efficient way to handle signature records.
