If your postal address changes, you can update it by going to Personal details > My details > Address > Replace Address. This will allow you to add your new address and archive your existing one. As was the case when you added your first address to Yoti, you can add your new one either via a document that contains it, or manually.
Please note that if you replace your address using an ID document that contains it, all details from that document will be added to your Yoti, not just the address. If you want to know more about this, please click here.
