It may not be possible to verify your details at this time. If you think you may have made a mistake, you can try again to verify your identity.
However you will need an alternative email address to that you used when you first tried.
If your next attempt is unsuccessful return to the government service you wanted to use and follow the guidance on the other ways for you to access the service you need.
Please note: If you scan your passport and take a selfie and it is accepted you can just submit one additional evidence and it will likely not require you to answer the identity test questions
