The account number you've entered can't be linked to this Account Online User ID at this time. Please register this account using a separate User ID. To do this, you'll need to sign off, return to the home page and select Register.
The consensus seems to be that people are unable to add the account to an existing Citi Account Online profile that has been set up for credit cards only; however people have been able to add it to banking profiles.
