Authorized user trade lines are revolving credit lines where someone uses the account as an authorized user account holder. “Authorized user” is the term used as the person is merely an authorized person to use the credit card, not someone who has an obligation for the repayment. This will make the trade line appear on the user’s credit report.
In addition, the authorized user will inherit the characteristics as well as the previous payment history of the account. A good standing account will, then, have increased credit scores with the addition of the authorized user to the account.
Authorized user trade lines work along with the course of time. There have been a number of changes in the industry and authorized user tradelines have managed to shift along with these changes as they come.
