Should I ship to an unconfirmed address?
While you're not required to ship to a confirmed address, address confirmation is useful because it provides a way for a seller to verify a buyer's identity.
We recommend against stating in your listing that you'll only ship to confirmed addresses. Since a confirmed address isn't a requirement for PayPal Seller Protection, this is an unnecessary restriction and might discourage a potential buyer.
You can create shipping labels on eBay to save time, money, and provide proof of shipment. eBay shipping labels are automatically generated from a valid shipping address.
