Hello @Seller_zkNXMWJTR54iq

Thank you for posting your inquiry to the Forums.

Your default return address is the address that will be used on all returns in a given store. It will be printed on the return label for all return requests, unless otherwise specified through your Return Address Preference. In some cases, the default return address may also be the business address that is associated with your selling account. You can add a specific return address for any of the stores that you sell in. I have included some help pages below that detail how to set a return address for your reference:
