Your statement may not be available online if it predates the time you became a cardmember, there was no account activity for a particular month or you had a $0 balance prior to 2002. System and product conversions can also affect availability. Also, if you are looking in the Immediately Available statements list on the Statements page, only your 12 most recent months of statements are available. Statements older than 12 months are available in the Archived Statements list. If you have converted accounts or your account number has changed due to lost or stolen cards, you might need to add the account. To do this from your Account Home, log into your Citi account online, click on Add Another Account to This User ID.
