What Is a Thin Credit File?

A thin credit file is a credit report that has few active credit accounts. This can make qualifying for credit and getting the best rates and terms more difficult. However, it doesn’t take much to go from a thin to a thick file.

Who Is Most Likely to Have a Thin Credit File?

People are most likely to have a thin credit file when they’re new to credit or infrequently use credit. These individuals tend to be:

• Young adults, because they haven’t had much time to open or use credit.
• New to the U.S., because their credit history in their home country won’t be transferred to the U.S. credit bureaus.
• Older adults, who might not have open and active credit accounts anymore.
• From low-income areas, as they may have fewer creditworthy friends and family members to cosign loans.
• Part of certain minority groups who may have had negative experiences with credit and the financial system.

How a Thin File Affects You

Most lenders rely on the information from your credit reports and your credit scores to make lending decisions. If you have a thin credit file, you might have trouble qualifying for new accounts. Even if you’re approved, you might receive less favorable rates and terms.

A thin file could affect you when you try to open or apply for:

• Credit cards
• A mortgage, auto loan, personal loan, or other type of installment loan
• In-store financing
• A rental home or apartment
• New utility, internet, or phone services
• Various types of insurance

How to Fix a Thin Credit File

Although having a thin file can make accessing some types of credit more difficult and expensive, there are ways to thicken your file. Here are some strategies:

Add Alternative Data to Your Credit Reports

One option is to add payments that you’re already making to your credit reports, such as monthly rent, phone, utility, and streaming service bills. Experian Boost® is a free feature that allows you to link the bank account you make payments from and add eligible payments to your Experian credit report.

Apply for a Secured Credit Card

Secured cards generally don’t require a good—or any—credit score. You need to put down a refundable security deposit that often determines your credit line. Use the card for a small monthly payment and then pay the bill in full each month to avoid interest charges while building credit.

Use a Debit-Credit Hybrid Card

Traditional debit cards don’t appear in your credit reports or affect your credit scores. However, some online-only banks and financial technology companies offer debit-like cards that can help you build credit. These might have low or no fees or interest rates.

Ask a Close Friend or Family Member to Add You as an Authorized User

When someone adds you as an authorized user on their credit card account, the credit card company may report the account’s history and usage to the credit bureaus under your name. This can thicken your file and help your credit score even if you never use the card.

Join a Lending Circle

Lending circles are organized groups that gather and contribute a specific amount to a shared pool of money each month. Each member of the circle receives the funds, and the recipient changes each month until everyone has had a turn. Some nonprofit organizations create and manage lending circles that help members build their credit and savings at the same time.

Open a Credit-Builder Loan

You can also add an installment loan to your credit reports by taking out a credit-builder loan. Unlike loans for making a purchase, the money you borrow gets locked in a separate account. Depending on the terms, you might unlock the funds once you pay off the loan.

Get a Creditworthy Cosigner

If you’re trying to get a loan and struggling to qualify or receive a good rate, you could try asking a close friend or family member who has good credit to cosign. The cosigner might help you get the loan, but they’re also taking on a legal obligation for the debt.

Monitor Your Credit as You Thicken Your File

Adding accounts to your credit report can help thicken your file, but building excellent credit also takes time. The most important factor in your credit score is your payment history: Try to always make your monthly payments on time. Only using a small portion of your credit cards’ credit limits, paying the bills in full to avoid interest charges, and only applying for credit when you need it can also help.

If you don’t have any credit accounts in your name yet, you can create your credit report with Experian using Experian Go™. You can then use the Experian Boost feature to add eligible bill payments, and you’ll receive other recommendations for building your credit.

Your Experian account also helps you track your progress with free credit monitoring, FICO® Score tracking, and real-time alerts when there are important changes in your credit file.
