Establishing and Building Credit
Add authorized user to build credit
You might not know this, but our internal team ran an analysis. Per that data, people first became authorized credit card users. If they used less credit three months later, their average credit scores went up. You can build credit by adding an authorized user to your account. Becoming an authorized user on a well-managed account could raise your credit score. Say a young person has little to no credit history. If they get added as an authorized user to their parent’s credit card, and that account is run well, it helps them build their own credit record. Here’s a quick pro tip: Before you add anyone as an authorized user, make sure the main account is in good shape. It should have a history of on-time payments and low credit usage. Doing this will raise the authorized user’s credit score.
Be selective when adding authorized user
Keep in mind that adding an authorized user affects both of you. Naming someone an authorized user can raise the main account owner’s credit use rate. That rate is a big part of keeping a high credit score. If you’re the main account owner, you need to choose carefully. If you add someone who has a history of paying late or overspending, it can hurt your credit. Talk to the authorized user about using credit responsibly. Set clear expectations for their spending limits and repayment rules.
Best Practices for Authorized Users
Choose right primary account holder
If you’re an allowed credit account user, pick the right main account holder first. That main account holder’s credit habits will affect your own credit score. You want someone with a great overall credit record. They should use very little of their allowed credit. They should also always pay every bill right on time. If you’re just starting to build credit, you can pick a family member. That family member should have used credit responsibly for many years. Here’s a helpful tip: Look up the main account holder’s full credit history. Ask your potential pick about their past payment habits. Also ask how much of their allowed credit they usually use. This will help you make sure they’re a good fit for you.
Overall Account Management
Both the main and approved account holders need to manage the account well. Main account holders should set clear roles with approved users first. They need to outline duties, set spending limits, and approve or deny credit requests per Point 5. Credit management tools recommend you check your account activity regularly. This makes it easy to spot possible problems or unapproved charges early. These are the key takeaways.
- You can raise your credit score by adding an authorized user. You just have to be careful when you choose that person.
- Using credit has real, important effects. People who own the main credit account need to understand these effects. People allowed to use that account need to understand them too.
- Watching your accounts closely helps you manage them well. Use our Credit Score Simulator to see how adding an authorized person could change your credit score. The U.S. does not ban buying tradelines. But using them to cheat or lie for gain is a crime, as noted in Point 3. It is important to use authorized user strategies responsibly and follow all laws.
Authorized user impacts
A 2018 study from Credit Sesame looked at people with fair credit. These people became authorized credit users. Just three months later, their credit scores went up nearly 11%. These numbers show how big an impact being an authorized credit user can have.
Positive impacts
Build credit
Being an authorized user can help you build your credit. You get added to someone else’s account that tracks all their payments. For example, say you’re added to an old credit card with perfect on-time payments. That positive track record will show up on your own credit history. Credit bureaus use these account details when calculating your credit score. Pick an account with a long, positive payment history to get the most benefit. Credit Karma recommends checking your credit report regularly after you’re added. This makes it easy to track your progress as you build credit.
Credit score improvement
Your credit score can go up if you become an authorized user. This happens when your credit usage rate drops after joining the account. We studied this trend and found a clear pattern. People whose usage dropped three months later had higher average credit scores. Credit utilization is a huge factor in your final credit score. It’s the comparison between your credit card limit and how much you owe. If the account owner has a low limit but a big balance, adding you as an authorized user raises your total available credit. This can lower your overall credit utilization rate. Try to keep your credit usage ratio below 30% to keep or boost your credit score. You can use our score calculator to see how different usage rates would change your credit score.
Access to credit
When you become an authorized credit user, you get more spending power. A lot of people find that extra power hard to ignore. Your higher credit limit can be really useful in some cases. You might find a big item on sale that you want to buy. Or you could have a surprise bill you need to pay right away. Say you need to get a laptop for work. If you don’t have the cash on hand, that extra credit can help you out a lot. Just remember to use that extra credit responsibly, and only buy things you actually need.
Negative impacts
Being an authorized user can have bad effects too. You could raise the main account owner’s credit usage ratio. That ratio is really important for keeping a good credit score. Adding you as an authorized user might make the main account holder spend more credit. That extra spending would push their credit usage rate higher. If the main account owner misses payments or can’t pay what they owe, your credit score can get hurt too.
No impact
Being an authorized account user might not change your credit score at all. There are two common reasons for this. First, the lender might not report this account to credit bureaus. Second, the account might have negative marks. If the account has a high balance and late payments, it won’t help your credit score at all.
Short – term financial benefits
You can use this account to buy all sorts of different items. You don’t have to pay for all your purchases right away. You can pay off the full cost slowly over time. There’s one important thing you should always keep in mind. The money you use for these purchases is money you’re borrowing.
Long – term financial impacts
Being an authorized user affects you long term. This kind of account can help you build good credit. It can also make your overall financial situation better. But you’ll run into problems if you use it carelessly. Don’t rely too much on your authorized user account. If you rack up a lot of debt with it, you’ll face money issues. That debt will also hurt your credit rating. These are the key points to remember.
- People who are authorized credit users get several nice perks. First, they can improve their credit scores. They can also build up their credit over time. They will also get easier access to credit overall.
- There are some bad effects you might run into. If you don’t handle your main account well, your credit score might get damaged. That’s one of these possible bad effects.
- Some situations won’t affect your credit score at all. These cases don’t change the score in any way.
- Before you become an authorized user, take a minute to stop and think first. Think about how it will affect your money right away. You should also think about how it will impact your money far down the line.

Tradeline rental risks

Legal status in the United States
Technically legal
Buying tradelines in the U.S. isn’t directly against the law. It’s important to know using them for fraud is a crime (Source). The basic act of purchasing tradelines is legal on its own.

Lenders and credit bureaus are very suspicious of this practice. They worry it can be used to lie about how responsible someone is with credit. People often buy trade lines to artificially bump up their credit score. This can lead lenders to make choices based on totally false information.
FTC’s stance
The Federal Trade Commission, or FTC, has added arguments to public records twice. These arguments raise questions about whether a common practice is legal. The FTC has shared concerns about this practice. No laws related to this practice have changed recently. No judges have ruled that buying tradelines is legal.
