The bulk proof of delivery program gives mailers the ability to receive signature proof of delivery records for applicable mailpieces without requesting them individually. This enhancement allows mailers to retain records longer than the Postal Service retention period and provides mailers a more efficient way to handle signature records.

Bulk proof of delivery service meets three key customer needs:

1. It frees the customer from having to request individual proof of delivery records or from placing PS Form 3811, Domestic Return Receipt, on each mailpiece (if applicable).
2. It allows mailers to retain signature records for longer than the Postal Service’s retention period.
3. It provides mailers with a more efficient way to handle signature records.

The bulk proof of delivery program is available to mailers who participate in Adult Signature Required, Adult Signature Restricted Delivery, the Express Mail Manifesting program, Signature Confirmation electronic option program, or if a mailer or a mailer’s third-party designee uses Electronic Return Receipt with the applicable extra service when printing privately-printed labels. The mailer’s Mailer ID (or the Mailer ID of a registered third-party with whom the mailer is working) must be used in the barcoded label or be placed in a Shipping Services file to participate. Mailers can receive bulk proof of delivery records on CD-ROM or a signature extract file accessed using SFTP/FTP, the secure SFTP protocol being preferred. CD-ROMs are produced twice a month — on the first day and the fifteenth day. The signature extract file is produced weekly.

The Postal Service protects all PDF files using 128-bit RC4 encryption techniques and provides a customer-specific key code to the mailer or the mailer’s approved third-party designee to access the data. A mailer must use its key code to access its encrypted PDF files. Acrobat Adobe Reader 7 or higher must be used for viewing, searching, and printing.

The United States Postal Service^® allows mailers who purchase Express Mail^® service or Signature Confirmation™ service, Adult Signature Required and Adult Signature Restricted Delivery, to request individual proof of delivery records in letter format by e-mail, fax, or mail. Customers can make these requests through the Track & Confirm site on usps.com or by calling 800-222-1811.

Additionally, customers who purchase other extra services, such as Certified Mail™ service, can obtain individual proof of delivery records with recipient signatures by purchasing Electronic Return Receipt service. Electronic Return Receipt service is available for purchase only at the time of mailing.
