Lists supported postage provider integrations, explains how to connect one (w/video demo), and how to use multiple accounts for a single carrier.
ShipStation provides a few options for connecting a postage provider so you can start creating labels. You can connect your existing accounts for any provider ShipStation integrates with, or you can enter your billing information for the providers already available in ShipStation.
For U.S. accounts, ShipStation provides access to a free Stamps.com account. This account is already added to ShipStation, just enter your payment method to start creating labels.
You can connect the following provider accounts to ShipStation. Click a provider to view their integration details.
Integrated Postage Providers
If you use a provider that does not appear on our list, we may not yet integrate with them. If this is the case, we recommend you do the following:
Contact your provider directly to express your desire to connect your account to ShipStation. They can then reach out to our integration team so we can work together to build the integration!
Add your feedback about this to our Product Feedback page. This is where our users can let our product team know this integration is needed!
This video shows how to add your postage provider accounts to ShipStation so you can add a service, get a rate, and create a label.

Important Notes About Postage Providers
Different providers require different information, and in some cases, you may need to log in to your provider account directly to locate it. For details on specific provider needs and connection processes, review the article for your postage provider in our Integrations Help guide.
When connecting multiple accounts for a single carrier, the first account you connect will be considered your primary account, which means it is the account automatically selected when you set that service from that carrier. (Multiple accounts not supported for all carriers.)
To set a different account as the primary account, open the carrier's Settings in ShipStation and check the box for Make this my primary account.
You can add multiple accounts for the same carrier by repeating the provider connection process. We highly recommend giving each account a unique nickname so you can differentiate them in the Services selection menu.
Not Available for All Carriers
Not all carriers allow multiple accounts in ShipStation. Please review our Carrier Integration Guide to see if your carrier supports this feature.
ShipStation always defaults to the Primary account for a carrier.
To select an account other than the Primary before creating a label, change the account using the Shipping Account drop-down in the Other Shipping Options section of either the Shipping Sidebar in the Orders grid or of the Order Details Screen.
Primary Account Notes
Certain ShipStation features only allow the carrier's Primary account.
For example, Return Labels and labels created directly in the Rate Calculator will always use the Primary account.
Shipping Presets do not provide the option to change the carrier account within the preset. However, you can still manually change the account on an order before creating the label.
