Key Takeaway: A thin credit file means you don’t have enough information in your credit history for a credit bureau to determine your credit scores. A thin file can make it difficult to get approved for a loan or credit, but you can grow your credit file if you take steps to build your credit.

Having a thin credit file means you don’t have enough credit history for the three major credit bureaus — Equifax, Experian and TransUnion — to get a clear picture of your credit and generate your credit scores.

A thin credit file can make it difficult to get approved for credit products like credit cards, mortgages and auto loans. If you are approved, you could wind up with less favorable terms, like a higher interest rate.

You can make your thin credit file more robust by focusing on building your credit history. Opening a starter credit card, like a secured card, can be a great first step. As an alternative to credit cards, consider Credit Karma’s Credit Builder plan. Credit Karma’s Credit Spark™, a bill payment reporting tool, may also be helpful. It can report accounts to the credit bureaus that don’t typically get reported, like utility accounts.  

Here’s how a thin credit file can negatively affect you and what you can do to begin building a credit history.

What does it mean to have a thin credit file?

A thin credit file means you don’t have enough credit history for a credit bureau to calculate a credit score. Your credit file can also be considered thin if you don’t have many open accounts or you haven’t used your credit recently enough. For example, one lender may view consumers with less than two active accounts as having thin files, while another lender may feel the same about consumers with less than five accounts. 

Why don’t I have a credit score?

You might find yourself missing a credit score due to a thin credit file if:

  • You’ve never had credit in your name. If you don’t have any credit listed on your credit reports, a credit bureau won’t be able to generate a credit score for you. This could be the case for you if you’ve never opened anything in your name. 
  • You’ve recently moved to the U.S. from another country. Credit history isn’t always transferrable between countries. If you’ve recently immigrated to the U.S., you might have to reestablish your credit with U.S.-based accounts before you can get credit scores from the three major bureaus.  
  • You’re new to credit or reestablishing your credit. It takes at least one account and six months of recent credit history reported to credit bureaus to generate a FICO credit score and at least one account and one month of recent credit history to generate a VantageScore credit score. The same applies if you’re trying to reestablish credit after closing your credit accounts or after a period in which you used only cash or debit cards.
  • Your credit file is split. A split credit file happens when your credit history is divided between multiple credit reports. While rare, this can happen when someone moves, changes their name or opens and closes accounts often. If your file is split, then you may appear to have less credit history than you actually do, making it hard for credit bureaus to generate scores. 
  • You were accidentally reported as “deceased” by the credit bureaus. Credit bureaus sometimes mistakenly mark people as deceased. This can happen when they get your file confused with someone else’s, when one of your credit accounts reports it accidentally or even when the Social Security Administration reports your number as deceased. Deceased people don’t have credit scores, so you might appear to have a thin file if that’s what the bureaus think.

How can I start building credit?

To make your credit file more robust, you’ll likely have to start building credit from scratch, as well as fix any credit report errors that may be contributing to you having thin credit.

Open a new credit account

You can’t start building credit unless you start using credit. Common credit account types include: 

  • Credit cards
  • Mortgages
  • Auto loans
  • Student loans
  • Personal loans

If you don’t have any of these accounts yet, consider starting with a credit-building account. Popular options include:

  • Secured credit cards: Secured cards are designed for people who want to build or rebuild credit. In fact, some secured card issuers don’t even check your credit. These cards are backed by a security deposit that you provide, which usually becomes your credit limit. When applying for a secured card, be sure to confirm whether the card issuer reports your monthly payments to the credit bureaus.
  • Student credit cards: These cards are unsecured just like traditional credit cards, but they’re geared toward young adults just starting their credit journeys. This means having little to no credit won’t be an obstacle for these cards. To apply for one, however, you must be an eligible student.  
  • Credit-builder loans: These loans differ from traditional personal loans because you don’t get the funds until after you’ve completed all of your payments. You pay off the loan in set installments each month, which are reported to the credit bureaus. The money you pay typically goes into a savings account. Once you’ve made all of your payments, the money is released to you and your account is closed. 
  • Credit Karma’s credit-builder plan: Credit Karma Money™ Credit Builder* is a type of savings account combined with a line of credit. You set aside a set amount from each paycheck to go into a savings account, and that money is reported as a payment against your line of credit with no interest or added fees. Once you reach $500 in savings, you can transfer that money out of the account for you to spend. 

Start paying your bills on time, every time

Payment history tracks whether you’ve paid your bills by the due date each month. It’s generally the single most important factor when it comes to your credit scores, which is why it’s so important for credit building. 

While it’s best to pay your bill in full, even paying the minimum balance due is better for your credit than not paying at all. 

Report and dispute credit report errors

You can get a copy of all three of your credit reports from annualcreditreport.com for free and then compare those reports to each other to check for inaccuracies. If you think you’ve been marked as deceased, have a split file or find other errors on one or more of your credit reports, file a dispute with the credit bureau attached to the erroneous report. If you are a Credit Karma member you also have access to Direct Dispute.™ This tool lets you dispute errors on your TransUnion credit report right from the Credit Karma app or your online account.

What’s next? Monitoring your credit

Fixing a thin credit file takes time and patience. By taking the steps to build your credit and correct any errors on your credit reports, your credit file will grow — and your credit scores should, too. Improved credit scores may help increase the likelihood of being approved for a loan and could result in better rates and terms.

As your credit improves, be sure to monitor it so that you can track your progress. Credit Karma offers free credit reports, as well as VantageScore 3.0 credit scores, from TransUnion and Equifax. Keeping an eye on your credit will allow you to spot any errors that may have reappeared on your reports.

FAQs about thin credit files

Having a thin credit file can make it harder to get approved for credit products like loans, mortgages and credit cards. If your credit file is too thin, you may be denied credit or face stricter application requirements to get it. If you do get approved, it may be for less favorable terms, like a higher APR. 

To generate a credit score, you need to show recent activity on a credit account. To get a credit score from VantageScore, you need at least one credit account with one month of credit history reported to the credit bureaus. This is a much shorter timeframe than FICO, which generally requires at least one credit account and six months of credit history reported to the bureaus to generate a score.

No, having a thin credit file isn’t the same as having bad credit. Bad credit typically indicates that you have derogatory marks on your credit reports, like a bankruptcy or a history of late payments, that contribute to your low credit scores. A thin credit file means that there’s not enough information in your reports to accurately generate a credit score. 

Yes, you can use Credit Karma to view your TransUnion and Equifax credit reports even if you have a thin credit file. Depending on your credit history, however, you may not immediately see credit scores from those bureaus. Other tools, like Credit Spark and the Credit Karma Money™ Credit Builder plan, might be able to help you grow your credit history.
