Is this legitimate? Since when does the Postal Service require
credit card information for Change of Address requests?
A valid credit card and a valid email address are required to complete the Online Change of Address process. For your security, the credit card billing address MUST match the address you are moving from or the address you are moving to. If you are unable to use a credit card and a valid email address, you will have the option to print the Change of Address form and then mail or deliver the printed form to your local Post OfficeTM
