Key Takeaways
- No federal statute makes the sale of authorized-user tradelines illegal per se, but the Federal Trade Commission (FTC) has written that it has never determined credit piggybacking to be legal.
- The FTC sued BoostMyScore (complaint filed March 6, 2020) and The Credit Game (temporary restraining order May 3, 2022; proposed permanent bans December 2022; more than $3.5 million refunded June 2025) under the FTC Act and the Credit Repair Organizations Act (CROA).
- The Credit Game case (FTC v. Rando) was a civil action, not criminal, but pairing a tradeline with a CPN or stolen Social Security number crosses into federal crime.
- A lawful authorized-user tradeline attaches to a real person with a real relationship to the account holder; ask hard questions before paying any broker.
Is Piggybacking Legal in 2026? The Honest Answer Is a Map
Imagine Maya, a graduate student with a thin credit file, scrolling past an ad that promises to add her to a stranger’s decades-old credit card for a fee. The pitch sounds tidy: pay a few hundred dollars, borrow someone else’s payment history, and watch your nest fill out almost overnight. Then a friend asks the question that stops her cold. Is this even legal in 2026?
It’s a fair question, and the honest answer is more layered than either the sellers or the scare-headlines admit. The practice at issue is called piggybacking: becoming an authorized user (AU) on an account you don’t actually use, so that account’s history reports on your credit file. Whether that’s allowed, encouraged, or quietly frowned upon depends less on rumor and more on what the Federal Trade Commission (FTC) has actually put in writing.
So let’s build this nest carefully, one twig at a time. We’ll separate what the law flatly says from what a federal agency has argued in court, and we’ll draw a bright line you can actually stand on. That line runs between a legitimate authorized-user branch and a scheme that can land someone in real trouble.
The one-sentence answer
No federal statute makes selling authorized-user tradelines illegal per se, yet the FTC has never determined that credit piggybacking is legal, and it has sued the companies that sell it.

No Federal Statute Bans Selling Tradelines
But “no statute bans it” is not the same as “it’s blessed and safe.” Those are two different claims, and the gap between them is where most people get misled. A thing can be un-banned and still be risky, still be a magnet for enforcement, still be built on misrepresentations that violate other laws. The absence of a specific prohibition is a real fact, not a permission slip.
"No federal law bans selling tradelines, so buying one must be safe and officially blessed."
No statute bans the sale per se, but the FTC has written that it never determined piggybacking to be legal, and it has sued the companies that sell it. Not banned is not the same as safe.
So this article stays inside a careful frame the whole way through: no federal statute makes commercial piggybacking per se illegal, and at the same time no regulator has declared it legal. Hold both of those in your hands at once. Everything that follows lives in that tension, and pretending the tension away is exactly how buyers get burned.
What the FTC Has Actually Written About Piggybacking
Here’s the part that rarely makes it onto a sales page. The FTC has written, plainly, that it “has never determined that credit piggybacking is legal.” Not “we’ve decided it’s fine,” not “proceed with confidence.” The agency’s own words refuse to give the practice a clean bill of health.
The FTC also addressed the argument sellers lean on most. Companies often point to the Equal Credit Opportunity Act (ECOA), the fair-lending law that requires card issuers to report authorized-user accounts, as if it protects buying and selling those slots. The FTC’s response was direct: the Equal Credit Opportunity Act “does not speak to, let alone protect, this practice.” In other words, a rule that says issuers must report authorized users is not a rule that says you may sell authorized-user status to strangers for profit.
You may run across an older quote from an FTC spokesman describing piggybacking as “legal.” Read it with the counterweight attached: the agency now says it never determined the practice to be legal. When the source itself has walked a statement back, the walk-back is the part you plan around, not the sentence a marketer screenshotted years ago.
The Lawsuits: BoostMyScore and The Credit Game
The clearest signal of how the FTC views commercialized piggybacking isn’t a quote. It’s a docket. The agency has sued the companies that sell it.
On March 6, 2020, the FTC filed a complaint against a company called BoostMyScore, targeting a business built on selling authorized-user tradelines. Two years later, on May 3, 2022, the FTC obtained a temporary restraining order against an operation known as The Credit Game, freezing its assets and putting a receiver in charge. Proposed orders that would permanently ban the operators from running or assisting any credit-repair business followed in December 2022, and in June 2025 the FTC sent more than $3.5 million in refunds to consumers who had paid in.

Over $3.5M refunded

One detail matters for accuracy: The Credit Game case (formally FTC v. Rando) was a civil enforcement action, not a criminal prosecution. The FTC used civil tools, injunctions, asset freezes, and refunds, the way it does against deceptive marketers. That distinction becomes important in a moment, because a different kind of tradeline scheme does cross into criminal territory, and it helps to keep the two apart in your head.
What the FTC Accused the Sellers of Doing Wrong
What exactly did the FTC accuse these sellers of doing wrong? The legal theories centered on two laws: the Federal Trade Commission Act, which forbids deceptive practices, and the Credit Repair Organizations Act (CROA), which regulates companies that charge a fee to work on your credit.
If you’re weighing any tradeline offer, this is the moment to slow down and ask hard questions rather than take a marketer’s word for the law. That instinct, verify rather than trust the pitch, is the single most protective habit you can build here.
The Bright Line: A Real Person Versus a CPN or Stolen SSN
Now the line that actually keeps you safe, because it separates a gray-area practice from a black-and-white crime. A lawful authorized-user tradeline attaches to a real person who has a real relationship to the account holder. A parent adding a child, a spouse adding a spouse, a business owner adding a trusted employee. The authorized user is a genuine human with a genuine tie to the account.
CPN
A so-called credit privacy number sold as a substitute for your Social Security number; it is frequently a stolen or invented SSN.
So whatever you decide about ordinary piggybacking, treat any offer that involves a new “number,” a “clean file,” or a way to “legally” stop using your real SSN as a stop sign. There is no lawful version of that.
Two Scenarios: A Real Branch and a Rented One
If you’re in Priya’s spot, a few questions protect you better than any purchase. Ask any seller directly whether they are registered under the Credit Repair Organizations Act and what they claim the law says, then check it against what the FTC has actually written. Ask whether the “authorized user” would have real access to the account, because the FTC treated the lack of access as evidence of deception. And ask whether anything in the offer involves a CPN or a new SSN, because that’s the fault line between a civil gray area and a federal crime. None of this is legal advice, and your situation may have wrinkles a stranger online can’t see. For a decision with real money and real timing on the line, a qualified attorney is worth more than a broker’s reassurance.
Action Items
Disclosure
Some lenders and credit scoring models may filter out, discount, or weigh authorized user tradelines differently in their underwriting decisions. Results vary based on lender policies, the specific scoring model used, and your unique credit profile. An AU tradeline does not guarantee loan approval or any specific credit score outcome.
Build a Nest That Holds
Back to Maya and that tidy little ad. The honest answer she was owed isn’t “yes” or “no.” It’s a map. No federal statute makes selling authorized-user tradelines illegal on its face, yet the FTC has never determined the practice to be legal, has said the Equal Credit Opportunity Act doesn’t protect it, and has sued the companies that sell it under the Federal Trade Commission Act and the Credit Repair Organizations Act. And the moment a “tradeline” offer reaches for a CPN or a borrowed Social Security number, the gray area ends and a federal crime begins.
Your credit file is a nest you’re building to last, not a stage set to prop up for one lender’s glance. The strongest twigs are the ones you place yourself: on-time payments, low balances, real accounts, and real relationships. If a legitimate family member’s account is on the table, understand the mechanics first and go in with clear eyes. If a stranger is selling you the law along with the tradeline, let that be the twig you leave on the ground. When the storm of a real application comes, the nest you built honestly is the one that holds.
Frequently Asked Questions
1. Is selling authorized-user tradelines illegal in 2026?
- No federal statute makes the sale of authorized-user tradelines illegal per se, but the Federal Trade Commission (FTC) has written that it has never determined credit piggybacking to be legal, and it has sued sellers under the FTC Act and the Credit Repair Organizations Act (CROA). The accurate framing is that it is not per se illegal and not blessed as legal either.
2. What has the FTC actually said about piggybacking?
- The FTC has written that it has never determined that credit piggybacking is legal and that the Equal Credit Opportunity Act does not speak to, let alone protect, the practice. It has also sued sellers such as BoostMyScore and The Credit Game.
3. Was the FTC case against The Credit Game criminal?
- No. FTC v. Rando (The Credit Game) was a civil enforcement action. The FTC obtained a temporary restraining order on May 3, 2022, proposed permanent bans in December 2022, and sent more than $3.5 million in consumer refunds in June 2025.
4. What makes a tradeline scheme a federal crime?
- A lawful authorized-user tradeline attaches to a real person with a genuine relationship to the account holder. Pairing a tradeline with a CPN or a fabricated or stolen Social Security number to obtain credit is fraud and a federal crime.
5. Does the Equal Credit Opportunity Act protect buying and selling tradelines?
- No. Sellers often point to the Equal Credit Opportunity Act, which requires card issuers to report authorized-user accounts, but the FTC responded that the law “does not speak to, let alone protect, this practice.” A rule that issuers must report authorized users is not a rule that you may sell authorized-user status to strangers.
6. Will buying a tradeline guarantee a higher score before a mortgage?
- No. Buying a tradeline offers no guaranteed effect on any score. Outcomes vary by file, and no honest source can promise you a number. It also means spending money on a practice the FTC won’t call legal and that mortgage underwriters increasingly scrutinize.
