USPS from ShipStation Troubleshooting Tips

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

Issue

How to troubleshoot or resolve

First Class Mail International (FCMI) shipments' tracking numbers not sent to marketplaces or customers.

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.

If you want ShipStation to include FCMI tracking numbers in notifications, go to Settings > Shipping > International Settings and enable the option Send non-trackable Tracking Number to Marketplaces at the bottom of the page.

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?

Contact the ShipStation User Success team with the tracking number(s) and created date(s) for the shipment(s). The ShipStation User Success team will evaluate the claim and respond within 24 hours.

I created a shipment using the First Class Mail International (FCMI) service and the Large Envelope or Flat package type but got a domestic shipping label.

Starting in early 2018, USPS requires all "Merchandise" shipped using FCMI to use the Package package type. The Large Envelope or Flat package type is only valid if the content type for the shipment is "Documents."

However, Stamps.com allows you to use the Large Envelope or Flat package type for any kind of FCMI shipment. The domestic shipping label you received uses the Stamps.com Global Advantage program. Once received, Stamps will relabel the shipment with a new label and any necessary customs information, and send the package on to its final destination.

See the Global Advantage Program section in the Stamps.com article for more details.
