The USPS also offers a signature proof of delivery service— Signature Confirmation. This provides mailers with the text name of the recipient, along with the date, time and ZIP Code.
This service is currently available for First Class Mail packages, Priority Mail, and Package Services parcels which include Parcel Post, Library, Media Mail and Bound Printed Matter. For security purposes, digitized signatures are not publicly displayed on the web site.
You can get actual signatures from the USPS by fax or mail. This service meets the needs of mailers who require a signature for high-value shipments, or who are specifically concerned with avoiding fraud.
You may combine Signature Confirmation with special services. As an add-on service to Delivery Confirmation, there is an additional cost when you upload (send) the transaction using your mailing system. The additional cost is greater if your local Post Office handles the transaction.
