How to Request a USPS Refund for Undelivered Mail Using WALZ “Refund-Eligible” Reports

With our recent improvements to the WALZ Last Status (WLS) reporting, we are able to provide efficient reporting to help facilitate a faster and easier refund process when mailings are Lost or Undelivered—or when a service you paid for is not fulfilled. The U.S. Postal Service (USPS) requires refund requests submitted online to be in a specific format, and WALZ now provides the documentation you need to request refunds from, when necessary.

In this article, you will learn about how WLS works to provide meaningful tracking information, and how you can use it to generate “Refund-Eligible” reports to upload directly to the USPS.

Walz Last Status: Reports When You Want, with the Information You Need

Included at no extra charge with your WALZ service, WLS is an automated reporting service that generates customized reports to inform you about the status of your mailings.

As we receive tracking information from the Postal Service, we interpret and translate each event into a meaningful mailing status, and you can configure your reports to include batches of mail at various stages of the process. (See the full list of WLS status options and definitions at end of this article.)

With our latest update, we added a new report, distinct from our typically detailed WLS reports. This “Refund-Eligible” report identifies mailings with a WLS status of Undelivered or Lost, and is provided in the format required by the USPS in order to request a refund. The refund-eligible report can be directly uploaded to USPS.

These changes greatly simplify the process of:

  1. Identifying mailings that are or may be eligible for USPS refunds, and
  2. Requesting refunds in the prescribed format to avoid unnecessary delays.

Ultimately, we want to help make sure the Postal Service is providing the full services that you are paying for.

What Makes a Mailing Refund-Eligible?

Under USPS terms and conditions, a refund is due when services paid for are not rendered between 30 and 60 days from the date of mailing. For example:

  • A mailing is not delivered to its destination after 30 days from the date of mailing, with no indication that a delivery attempt was made or that mailing is being returned to sender.
  • A piece of Certified Mail is confirmed as Delivered, but the sender doesn’t receive the signed Return Receipt, known as a “Green Card.”
  • The customer paid for Return Receipt or Return Receipt Electronic (RRE) service, but the USPS fails to collect a signature upon delivery of Certified Mail.

In each of these cases, a refund may be due because the customer paid for a particular service, and it was not provided by the USPS.

How to Request Your Refund

When using to create and manage your Priority and Certified Mail letters, all tracking information from USPS is stored in your account.
