An Authorized User Tradeline is when you are added as an authorized user to someone else’s established credit card account. If the card issuer reports authorized users, the account’s history, credit limit, balance, and payment history may appear on your credit report.
For credit repair clients, a tradeline may help strengthen the positive credit history in your overall profile, but results vary and a specific credit-score increase or approval is never guaranteed. Tradelines work best alongside responsible credit habits and addressing inaccurate negative information.
