Authorized user tradelines are typically revolving lines of credit on which someone places another as an authorized user account holder. The tradeline then appears on the user’s credit report. It is called an “authorized user,” because the person added is merely authorized to use the credit card, but has no obligation of repayment. In addition, the authorized user inherits, so to speak, the previous payment history and characteristics of the account established by the primary cardholder. This is why credit scores can increase when a person is added as an authorized user to an account in good standing (and why credit scores can decrease if that same person is added to an account in bad standing).
If you order a tradeline, it should be on your report within 30 days, tops. If the tradelines do not post within 30 days, then the company either dropped the ball or there is something wrong with your credit report (security freezes, fraud alerts, etc.)
