What is piggybacking — and is it worth it?

Clever people are always looking for ways to improve their credit score, and one of these methods is piggybacking. When it works, it can lead to a significant increase in your credit score and you could use it to make a few extra bucks if you already have good credit. But its legality is unclear, it’s frowned on by the credit industry – and it isn’t guaranteed to work.

What is piggybacking for building credit?

Piggybacking is a tactic where one person seeks to raise their credit score by becoming an authorized usermore info button on another person’s credit card account.

How can piggybacking raise my score?

Here’s the basic idea: As a cardholder makes on time payments on a card, the provider reports that cardholder’s payment history to the credit bureaus (Equifax and TransUnion). This, in turn, increases their credit score.

Now, let’s say that cardholder adds you to their card as an authorized user. The provider may then report the card’s account activity for you as well. If you’re lucky, the card’s entire payment history shows up on your credit report and raises your credit score.

Without doing much, your credit score goes up. That’s piggybacking in a nutshell.

Piggybacking is often used for two reasons:

• Forward-looking parents who want to help their kids build credit early on. You can’t get your own credit card before you turn 18, but piggybacking can be a way for kids to get a head start on building credit before this age. Many personal finance experts recommend it, and the credit industry is mostly OK with it.
• People with shaky credit looking to boost their scores. Someone might piggyback off a stranger’s card to temporarily raise their credit score. This could be helpful if, say, they’re applying for a car loan soon and want a lower interest rate. The credit industry does not look upon this method fondly.

Is piggybacking legal?

The legality of piggybacking is unclear. Many banks frown upon it — especially when it’s between strangers. They might even argue it constitutes fraud. However, it’s currently a legal grey area. Providers seem to be more accepting for piggybacking among family members.

More controversial are credit-repair companies that attempt to leverage the practice for profit. Such a company pairs two strangers — one with a credit card and a good credit score, the other who wants to become an authorized user. Then, it acts as the middleman in a for-profit transaction. The authorized user pays a fee to be added to the other person’s account, and the cardholder gets a cut of that fee.

Does piggybacking actually work?

Piggybacking isn’t always effective. Some providers don’t report payment activity for authorized users. Even if you find a provider that does, it might not consistently do so. If you’d like to try piggybacking, call the card provider and ask about their reporting.

When piggybacking does work, it can produce noticeable results. Many parents have helped their children build strong credit scores before the age of 18. A stranger on someone’s card account could see a significant jump in their credit score — though it’ll only last as long as they remain an authorized user.

Which card providers allow authorized users?

Most major credit card providers typically allow authorized users with almost no restrictions, although some may limit authorized users to spouses only. Most commonly, the individual you add to your account must be at least 13 years old.

Can I boost another person’s credit score for a fee?

If you have a good credit score and need extra cash, you could add users who need to boost their credit. The most common way to do this is through a credit-repair company that offers tradelines — or credit accounts — for sale.

Here’s how it works: You rent access to your good credit history by adding an authorized user selected by the credit-repair company. The company charges a fee to the person looking for the boost, and then you receive a portion of it as payment. It’s important to note that you’re not giving them a physical credit card, you’re simply adding them as an authorized user to a card account that they don’t know the number, expiry date or CVV for – which ultimately means they can’t spend your money.

Piggybacking companies

Companies that can help you with piggybacking include:

• Boost My Score. BMS sells access to accounts with positive credit histories for a fee. Prices and risk are generally high, with many consumers complaining they never saw an uptick in their scores.
• Credit repair companies. There are plenty of credit repair companies, both online and with brick and mortar buildings, that use piggybacking as a form of credit repair. Again, proceed with caution.

How much does it cost to piggyback on someone’s account?

Piggybacking isn’t always cheap. It could run you more than $1,000 to get on an aged, high-credit-limit account. Though it’s likely the most expensive option, this type of hack could potentially provide the largest boost to your credit score.

How much could I earn by allowing someone to piggyback?

If you take on an authorized user through a tradeline service, you’ll often earn between $125 and $275 while that person remains on your account. The time period is typically one to two months. You might earn more if your card has a high credit limit and has been open for a long time.

Downsides of piggybacking

Consider these risks if you want to be added to someone else’s account:

• Privacy. You’ll have to provide your legal name, date of birth and Social Insurance Number to the person adding you as an authorized user.
• It might not work. Though most major providers report payment activity for authorized users, credit-scoring models might not incorporate your piggybacking into your credit score.
• Piggybacking may not get you what you want. Many people piggyback for a temporary credit-score boost before applying for a loan or other credit product. Even if your score increases, you can’t be sure you’ll be approved for whatever you’re applying for.
• It’s temporary. Eventually, you’re removed as an authorized user after your piggybacking arrangement ends. That means you’ll stop receiving the payment reporting that boosts your score, and your score will slowly return to its previous level.

Taking on a piggybacker carries some risks too:

• Your provider could shut down your account. This is a big potential downside. For the most part, card providers don’t like for-profit piggybacking, which likely violates your terms of service.
• Not all piggybacking companies are reputable. The credit-repair industry attracts many untrustworthy operators. Before working with a tradeline company, make sure it’s reputable.

Bottom line

Piggybacking could be an effective way to build credit, but it comes with risks and sits in murky legal waters. The safest option is to only piggyback among family members. If you’d like to work with a credit repair company, do your research and know the risks before you divulge any of your personal or financial details.

Frequently asked questions

• Does it cost anything to add an authorized user?

  Not in most cases. Some providers charge a fee to add an authorized user — but usually only if your card has an annual fee. Check your card’s terms and conditions or call your provider to make sure. If you’re adding an authorized user and want a second physical credit card, you may have to pay for the card.

• What is considered a good credit score?

  Typically, lenders consider the “magic number” to be 650. Anything over 650 is usually referred to as good to excellent, while anything under 650 will likely be regarded as fair to poor. Learn more about credit scores in our guide here.

• What is a secured card?

  It’s a card designed to help you build or rebuild your credit score by making responsible payments. When you open this type of card account, you will need to put down a security deposit as collateral. If you fail to pay your card bill, your provider can take this deposit to pay off what you owe. With this financial guarantee, providers are more willing to accept you as a customer — even if you have average or low credit.
