As a UNIQLO account holder you can add more than one address to your UNIQLO account. To add another address, log into your account and go to the ""ADDRESS BOOK"" section of your account. You can even make any address your default address allowing you to shop even faster!
Please make sure, that the address saved in your PayPal account is the correct one if you pay via PayPal-Express, as the system will take that address even if you are logged in.
