Will becoming an authorized user on a relative's credit card increase my credit score? I currently have only one Capital One card with a $500 limit that is at zero. Shouldn't I see an increase if I proceed with the above? Also, his balance is roughly $300 with a $9,000 limit.
It's the age or length of credit history that Brammy is talking about, not your actual age. So if become an authorized user on a credit card that has a long history, i.e. open for several years with a solid payment history, and low utilization, then I agree that this should help increase your score.
