When USPS makes an APV adjustment on a package you shipped through Pirate Ship, you'll receive a notification to the email address associated with your account with these details:

  • The tracking number for the shipment, linked to the label in Pirate Ship

  • The reason for the adjustment

  • The amount charged or credited to your Pirate Ship account

The USPS APV Program is automated, and sometimes those robots make mistakes 😅 If you're sure your package is what you said, you can file a dispute!

To begin a dispute, head to that shipment either by looking up the tracking number or by using the link in the email, and click the “Dispute this adjustment” link:

When you click this link, a popup will appear asking you to describe why you’re disputing the charge:

For example, you can explain “All my orders weigh 15 ounces with no variation,” or “This was not a Flat Rate Envelope,” to make sure USPS knows what they’re looking for!

Once the adjustment has been disputed, you’ll see that reflected right on your shipment next to where the carrier adjustment is listed:

This will also be shown over on your Carrier Adjustment Report so you can keep track of all of your disputes in one place!

Note that USPS typically takes up to 15 business days to process disputes once they're filed. It's only possible to file disputes up to 60 days after receiving the notification.


Once USPS approves the dispute, your account will be credited for the amount of the adjustment, and Pirate Ship will send you an email letting you know 🙌 This will also be reflected on the shipment and in your Carrier Adjustment Report.

If you have any questions or concerns about any adjustments that USPS has made to your account, just contact Pirate Ship's customer support and we'll help you figure it out 👍
