As soon as your account is open and ready to fund, you will receive an email from us. In some cases we may follow up to request additional information in order to verify your identity and establish your account. In these cases you will receive an email from us requesting certain documents be securely uploaded to us through a link we provide.
All of Us requests personal information, including financial and tax identification information, in order to comply with "know your customer" rules. We’ll request personal information from both new customers and long-standing customers. As a financial institution, we comply with an SEC customer identification rule of the USA Patriot Act of 2001. This rule requires us to put procedures in place to verify the identity of any person seeking to open an account and to maintain records of their information. All of Us must also determine whether a customer appears on any lists of terrorist organizations provided to broker-dealers by any government agency. We don’t use this data for anything other than the fulfillment of our regulatory requirements.
