if I just went to the registry and I had to renew my registration and I also paid to change my address but they didn't change the address and I didn't notice till I left can I go back and not have to pay to do it again

Yes. A customer service representative will make that correction for you. There won't be a charge. You may need to speak to a supervisor at the check-in booth to point out the error.

First of all they don't charge you to change your address But it's easier to do online and it's free Go to the Rhode Island DMV website look at forms and fees and then look at your change of address form under online services
