What a tradeline is
Every credit card, loan or line of credit on your report is a tradeline. Each one shows the lender, opening date, limit, balance and payment record. A primary tradeline is an account in your own name, and you are legally responsible for it. An authorized user tradeline is someone else's account that you have been added to. You may use the card, but the primary holder owes the debt.
When the issuer reports authorized users, that account's history can appear on your file, sometimes back to the date it was opened.
How bought tradelines work
Sellers match you with a person who has an old, low balance card. For a fee, that person adds you as an authorized user for a set period, often about two billing cycles. You never get the card. After that, you are taken off, and the account may drop from your report.
Prices rise with the account's age and limit, and can reach hundreds of dollars or more per seat. Selling this kind of access is not specifically outlawed in federal law, but it often goes against card issuer rules, and sellers may misuse your data or disappear.
What can go wrong
- Modern scoring models try to limit it. FICO has adjusted its models to reduce the effect of accounts that look bought.
- Lenders may look deeper. Mortgage underwriters often ask about authorized user accounts or exclude them from review.
- It may not report. Not every issuer reports authorized users, and sellers cannot control when a bureau updates.
- The primary user can mess up. A late payment or a high balance on that account can hurt you while you are on it.
- False claims. Saying the account is really yours on an application can be fraud.
Files already full of recent negatives tend to get the least out of this. A bought seat does not hide a collection or a late payment.
Better options
| Option | Cost | Why we prefer it |
|---|---|---|
| Family authorized user | Usually free | Real relationship and long term account |
| Secured card | Refundable deposit | Your own primary history |
| Credit builder loan | Low interest and fees | Adds an installment account |
| Rent or bill reporting | Free to small fee | Uses payments you already make |
Primary accounts you control keep building long after a seat would have ended, and they cost much less over time.
If you still consider buying
Ask what happens if the account does not appear, who holds your data and when you will be removed. Avoid anyone who promises a set number of points, asks you to use a CPN or tells you to hide the arrangement from a lender. Then compare the price against what that same money could do by paying down your current card balances.
Questions people ask
Are tradelines legal?
Being an authorized user is legal, and paying for it is not expressly banned by federal law. It may break issuer terms, however, and lying about it on a loan application can be fraud.
How long do authorized user tradelines stay?
They generally report for as long as you stay on the account, and may disappear soon after you are removed. Purchased seats often last just a few months.
Can you get a tradeline for free?
Yes. A family member or trusted friend can add you to their card. Choose someone with low balances and a clean record, and be sure the issuer reports authorized users.
