The purpose of USPS Shipment Confirmation Acceptance Notice (SCAN) Form 5630 is to save time. Without SCAN Form 5630, the USPS needs to scan each individual shipping label. This can be time consuming if there are a large number of shipping labels. Instead of scanning each individual shipping label, USPS scans the SCAN Form 5630 once, and uploads every shipping label from that day to the USPS systems.
In order to print USPS SCAN forms, you must enable the USPS SCAN Form Printing on your device.
