Do you want to know how to change the address and region on your PS5 Account? You can go to settings, then users and account and change the address. This will not change the region, but will be used for identification purposes when contacting Sony. If you go to the PS Store and go to more, then storefront country. You can change the region of the PlayStation store. Otherwise, create a new account with a different country and set that account to primary PS5 and share your games and ps plus.
