The designations I9, R9, O9 define the type of credit account. The “I” stands for Installment. The “R” stands for Revolving and the “O” stands for Open. Open, in this case, means that the bill is due in full and has a variable balance. These terms are used for credit reporting purposes.
The “9” means that the account has been “charged off”, or written off. This is not good. In fact, a charged-off account is considered a seriously negative item on your credit report. It will have a serious negative impact to your credit scores for up to seven years. Avoid charge-offs if you can.
