Lessons Learned from U.S. Postal Service’s Internet Change of Address Billing address of credit card used for identity verification must match Ship's address, or a hard copy Postal Service Form 3575 (available from the FPO) will be required for the change of address Only ".mil" or ".gov" email addresses will work on USPS iCOA and not the Sailor's / CIVMAR’s "personal" (AOL, Yahoo, Hotmail) email account The USPS iCOA cannot be used to change addresses from the Ship's old "non-standardized" address to their new virtual mailbox address
