How do I change my return address on a return label?

Within EasyPost, there are 3 different address types you can enter for your shipment label.

1. The recipient address, known in EasyPost as the to_address
2. The sender address, known in EasyPost as the from_address
3. The return address, known in EasyPost as the return_address

Once you create your shipment, you cannot go back and edit any of the information that you have passed into it as it becomes permanent once you've made the request to our API. The invalid shipment would need to be voided, and an entirely new shipment would need to be created in its place. If you create a shipment with only a to_address and from_address, EasyPost will automatically default the shipment label to set the return_address to match the from_address you've already entered.

It's best practice to enter all 3 addresses on your shipment. There are times when the original sender address will not actually be where the package should be returned in the event of a return. In that case, you'd want to ensure that you've manually entered a different return_address than the from_address on the shipment object. 

You can read more about the Address Object and the Shipment Object in our API Documentation.
