Discover partners with the USPS to mail your publications. We send you a Postal Verification once we deliver your papers to the post office. Once your papers are printed and we verify USPS receipt, our service has been provided and it is the USPS’s responsibility to deliver your publications. If your paper does not appear to be arriving in mailboxes within a few weeks of the Postal Verification, contact us and we’ll open an investigation. Over the last 25 years, 98.2% of orders were delivered within the timeframe. In the unlikely event that a problem does arise, we’ll work through our channels at the USPS to help resolve it.
