How to buy a tradeline safely

How paid authorized-user spots work, the warning signs of a scam, and what to ask before you pay.

Checked November 2026How we research

Short answer If you buy a tradeline, pay only for a plain authorized-user spot on a real card. Get the bureaus, the posting date and the refund terms in writing, and walk away from anyone who promises a score, sells a "new credit identity" or asks you to lie on an application. Even a legitimate tradeline is a short-term boost that some lenders ignore, so it should never be your whole plan.

How a paid tradeline works

A tradeline is any account on your credit report. When a cardholder adds you to their credit card as an authorized user, the issuer often reports that card on your report too, including its age, limit and payment history.

A paid tradeline is the same thing, arranged by a company. The company pays a stranger with an old, clean card to add you for a set period, often one or two statement cycles. You never get the card or use it. When the period ends, you are removed.

Red flags that mean walk away

What a legitimate seller looks like

A legitimate seller explains how authorized-user accounts work, says plainly that results vary, and answers questions before taking money. It puts the terms in writing and gives you a way to check that the account posted. It also tells you when it will not help, such as when you have recent late payments or a lender that ignores authorized-user accounts.

Questions to ask before you pay

Realistic expectations

Even if everything goes right, keep these limits in mind:

Better alternatives to try first

  1. Ask family. Being added to a relative's card is free and can last for years. See how to ask family to add you.
  2. Open an account in your own name. A no-fee secured card keeps building history long after any paid spot ends.
  3. Add a credit-builder loan if you want a loan on file. Compare costs in our credit-builder loan guide.
  4. Turn on free rent reporting. It helps with newer scores. See rent reporting compared.
  5. Fix errors. If something on your report is wrong, dispute it for free with the bureau.

If you think you were scammed

Stop paying, save every message and receipt, and report it to the FTC at ReportFraud.ftc.gov. You can also send a complaint to the CFPB. If you gave out your Social Security number, check your reports at AnnualCreditReport.com and think about freezing your credit at each bureau.
