If you don’t have a NINO or UTR number, then we’d need your residential address. Where your residential address isn’t in the UK, then we would also need details of either a valid, in-date state issued national identification card or a valid in-date passport. If you’re required to provide information on either a state issued national identity card or valid in-date passport, but don’t have either, you should get in contact via our contact us page to confirm this in order for us to assist you further.
