This article is for customers that already have a Coinbase account who also want a GDAX account. If you do not have a Coinbase account but would like a GDAX account, please follow the steps here. Please note that if you have a personal Coinbase account but want to create an institutional GDAX account, we require you to "Create Account" at www.gdax.com and use a new login email not associated with your personal account.
GDAX leverages Coinbase’s proven infrastructure to securely store funds and private information. This also simplifies the GDAX sign up process because you won’t need to provide us with information you’ve already given to Coinbase.
However, because GDAX has higher identity verification requirements, you may still asked to provide further information during account creation.
