The USPS® EPM® Plug-In for Microsoft® Office is a free download from Authentidate® * that enables users to easily use the U.S. Postal Service® Electronic Postmark® seal to electronically sign and ensure content integrity by incorporating a trusted date and time stamp on Microsoft® Word and Microsoft® Excel documents. It provides for truly long-term verification of content or electronic signature authenticity. The EPM Plug-in has been tested by Microsoft to integrate with Microsoft Office.

Truly Long-Term, Trusted Authenticity of Microsoft Office Files
USPS EPM seals issued by Authentidate, and applied to any document through the Authentidate Plug-In, are stored in an approved and highly secure environment for up to seven years from the date of application. The USPS EPM seal does not need to be renewed each year like most digital signature products. This electronic timestamp authorized by the U.S. Postal Service enables detection of document tampering and verification of a document's authenticity online. The U.S. Postal Service® serves as the backup verifier for all USPS EPM seals applied.

Imagine the time, cost and energy saved! Instead of printing your Word or Excel documents that need to be signed and sent, simply keep your documents in their native form, electronically sign them with an EPM seal and save them, or send them through any email system.

To get started using the EPM Plug-In for Microsoft Office, just create an account, download the software and click the EPM menu item in the Word or Excel toolbar to apply an EPM seal to a document.
