The Electronic Verification System (eVS) allows high-volume package mailers and package consolidators to document and pay postage, including special services fees, using electronic manifest files. Mailers transmit the files over the Internet to a Postal Service database. eVS is designed to make it easy for high-volume package mailers to take advantage of destination entry rates.
eVS mirrors our existing manual manifest process but does so electronically. The Postal Service captures sampling data that is used to monitor postage accuracy after the mailing arrives at the destination entry Post Office. Instead of reconciling sampling data against individual manifests, the Postal Service reconciles it against all manifests received from the mailer during the month.
