In order to change the address on the account, you will need to cancel the existing policy and purchase a new one. Each renter's insurance policy is attached to a specific address which is why a new policy must be purchased in order to change the address.
For instructions on how to cancel your current account click here.
After canceling your account, you can purchase a new policy online at gradguard.com with the updated address.
*Note: If you are currently living in on-campus housing and are moving to a different dorm/apartment that is also on-campus housing, your address does not need to be updated.
