Sometimes it's necessary to manually edit an address in ShipStation so that it's different than the one from your marketplace. However, the corrected address can be overwritten during the order sync process. ShipStation lets you lock in your changes so they are not overridden by the marketplace.
To use this feature:
1. Find the order that needs its address changed. (The order can be in any status and found in either the Orders or Customers tabs.)
2. Open up its Order Details window.
When the pop-up is open, look for the Buyer / Recipient Info section in the top center.
3. Click Edit to make changes.
Once you've made any manual changes to the address, the address will be locked automatically. The locked-in address will take priority for this order and any future order updates coming in will not impact this specific order's locked address.
If you want the order to later update to match the marketplace, click Unlock Address in the order details window and update your store.
This change is on a per-order basis, so any future orders containing this address will not be impacted by a locked address on a previous order.
