A tradeline is any account that appears on your credit report. When you're added as an authorized user (AU) to someone else's credit card account, that account's positive payment history can help boost your credit score. This practice, known as "tradeline piggybacking," has been used for decades to help consumers build or rebuild credit.
Tradelines work because credit scoring models like FICO and VantageScore factor in the average age of accounts and payment history from all tradelines on your report-even ones where you're just an authorized user.
When you become an authorized user, the primary cardholder's account history is added to your credit report. Factors that impact how much your score improves:
Accounts that have been open for 2+ years with perfect payment history. These are the most valuable because they immediately boost your credit age and show a long track record of responsible use.
Accounts where you're the actual account holder. These require credit approval and build your credit history from scratch, but take longer to show results.
Accounts that have been established with a credit management company. You become an authorized user, and the company handles all payments. Best for quick score boosts.
The most common type for sale. You get added to someone else's account as an authorized user. The account's history reflects on your credit report.
Quick boost needed? Seasoned AU tradelines (12+ months old)
Building from scratch? Primary tradelines with credit management
Best value? Mid-tier aged tradelines (6-12 months)
As an authorized user, the following information appears on your credit report:
