Two situations, and they have different answers.
The check did not pass
Usually this is a photo problem rather than a you problem: glare on the document, a blurred edge, a cropped corner, or a selfie taken in poor light. You can try again.
If it still does not pass, contact support and we will take another look ourselves. Your balance is safe the whole time, and you can carry on earning.
You do not have a government ID
Identity verification is required where we ask for it, and there is no alternative way to complete it. We cannot confirm identity without a document to check a photograph against.
If you do not have a passport, driving licence, national ID card or residence permit, you can still use RewardEarn and still earn, but you will not be able to withdraw. We would rather say that plainly than leave you waiting on an exception that is not coming.
You would rather not verify
That is your choice, and nothing bad happens. Your account stays open and your balance stays yours. Withdrawals stay on hold until the check is done, and you can come back to it whenever you like.
