It is a recent change: the authorized user information is not taken into account by the three credit score bureaus any more, so no authorized user can build any score this way. Fair Isaac Corporation’s newest FICO scoring model ignores authorized user accounts when calculating Classic FICO credit risk scores. As it is stated on the Company’s website, this action is intended to protect lenders and FICO scores from abuse of authorized user credit card accounts by a new kind of credit repair service that sells consumer credit card histories to credit applicants in order to purposefully misrepresent the applicants’ own credit history to lenders and other businesses.
