You can create an Amazon wishlist to add and track items of your choosing and hide your full address from third-party sellers who provide items. When you first create a list, select “You” under “This list is for” to keep your address private. Your wishlist is public by default.
Here’s how to hide your Amazon wishlist address;
Log into your Amazon account. Click the link for “Gifts and Wishlists” at the top of the page above the search box. Check if your address is visible by clicking "See what they see." If you do not see "Ship to: No Address Entered" go back and click "Manage This List." “Edit Settings.” Go to the “Ship to Address” and select “None” then SAVE.
Amazon declares that to protect the privacy of the list owner, only the registrant's name and city will show. If you buy from a seller, the default shipping address will not be available to you unless the list owner enables third-party address sharing.
Check your settings and if you are still uncertain, contact customer service for help.
