how I change my mail from PO Box to my new address

Submit a permanent change of address at usps.com. USPS will notify most of your mailers for you.

you need to notify everyone you receive mail from that your address has changed ( you normally can change your mailing address online for banks and credit card companies ). Also, you can go online or inside the post office and fill out a change of address form to reroute your mail to your new address for up to a year.
