Having trouble addresses for Puerto Rico, Virgin Islands (U.S.), Guam, American Samoa, Marshall Islands, Northern Mariana Islands, Palau, or Federated States of Micronesia? Following these steps should help:

If you're a private mailbox holder, do not use "Box" for your mailbox number, instead use # or PMB. This will ensure that your address is not mistaken to be a P.O. Box, and that orders can ship to you via means other than the U.S. Postal Service.
