First and foremost, providing this information is safe. We’ve taken all the necessary internal steps to ensure that your information will be encrypted and is not used for anything beyond verification, processing withdrawals, and tax information.
In order to complete withdrawals we require a valid mailing address, birthday, and social security number. This enables us to have the tax information required from our users should they earn $600+ a year and receive a 1099 tax form.
