I need to change my address on my license and registration, I have moved but stayed within Post Falls. What documents do I need to bring to change my address?

you can pick up a change of address form from the DMV or Drivers license and they will change the either do it at the desk or send you a corrected registration in the mail. The driver's license will be updated in the system. Unless you want it to match on the license then you have to physically go into department.

A piece of mail, lease agreement, or your loan application for the house something with your name and new address on it.
