The Postal Steward™ eVS Solution by Engineering Innovation, Inc. helps organize your electronic verification data before submission to the
United States Postal Service, and presents the data to you after processing.
Electronic Verification data provides tracking and identification information about specific mail pieces and mail shipments. This information
is stored in a shipping services file (SSF), a file whose fields are defined in the United States Postal Services Publication 199. The Postal
Steward™ website serves as a portal to view SSF data in a more user-friendly format, view shipment status, and manage the users that can
access those files.
For more information on the Postal Steward™ website, contact EII customer support. For more information on eVS and SSF data, refer to Pub199, available at Postalpro.usps.gov.
