Here are some common issues, potential causes, and troubleshooting tips.

Issue |
How to Troubleshoot or Resolve |
|---|---|
|
When I try to void a label, I receive the error message 'Authentication Failed'. |
If you void a label and receive this error message, it could be that you activated ShipStation Carriers by connecting it to an existing Stamps.com account and have updated that account password but haven't updated the password in ShipStation. To update your password in ShipStation, go to |
|
First Class Mail International (FCMI) shipments' tracking numbers not sent to marketplaces or customers. |
What it means: The tracking number provided for FCMI shipments is not always fully trackable and will often not provide any additional tracking details beyond the shipment leaving the country. Since these tracking numbers do not always provide full delivery information, ShipStation considers them to be "non-trackable" and will not include them in notifications by default. What to do: If you want ShipStation to include FCMI tracking numbers in notifications, go to Despite the wording of the setting, it applies to both marketplace and customer notifications. |
|
My Priority Mail Express shipment arrived late, how do I get a refund for the late delivery? |
Email shippersupport@stamps.com with the tracking number(s) and created date(s) for the shipment(s). The ShipStation Support team will evaluate the claim and respond within 24 hours. |
