If you're having issues connecting your carrier or postage provider account to ShipStation, follow the steps below:
Review Support Resources
Our Integration Help Guide includes an article for each of our carrier integrations, which include detailed steps on how to connect the account to ShipStation and what standard and additional features the integration supports. We also include connection-specific troubleshooting tips and links to partner resources that can help address issues you encounter when connecting the carrier.
Try alternate addresses
Some carriers require the same Ship From address in ShipStation as is listed in your carrier account. If the Ship From address you're using results in an error that states the address is incorrect, try using alternate addresses that could be used in the carrier account. For example, if you moved recently, try using the old address in case the carrier's database has not been updated yet.
