Your credit score can vary depending on the bureau providing the report. While small differences are normal, larger gaps may raise concerns. Credit bureaus like TransUnion and Equifax collect financial data to create reports that lenders use for credit decisions. Understanding how they work and why their scores differ can help you make better financial choices.
Credit Bureaus
Credit reporting agencies collect and maintain financial data to create credit reports lenders use. While the three major bureaus in the U.S. - TransUnion, Equifax, and Experian - serve the same purpose, each manages its records, meaning the information in their reports can vary. No single bureau is more important than the others, as lenders may use any of them to assess creditworthiness. While there are over 50 consumer reporting companies, TransUnion and Equifax are two of the most widely used, and understanding their differences can help you better interpret your credit report.
What Credit Bureaus Do
Data collection. Credit bureaus gather financial information from banks, credit issuers, and public records to create credit reports. This helps lenders assess your creditworthiness.
Credit activity. Reports include details on your loans, credit cards, and other financial accounts and track how you use credit over time.
Account status and balances. Bureaus record whether your accounts are open or closed and their current balances to give a snapshot of your financial obligations.
Payment history. Your report shows whether you make payments on time or have missed any, which impacts your credit score.
Debt collections and bankruptcies. This information is included in your report if you have unpaid debts sent to collections or have filed for bankruptcy.
Account timelines. Reports list when accounts were opened or closed, helping lenders understand the length of your credit history.
Credit scoring. Using collected data, bureaus calculate credit scores based on either the FICO or VantageScore models, which may result in variations across different reports.
How the Credit Bureaus Collect Information on You
Personal information. Credit bureaus gather your name, address, Social Security number, and date of birth from lenders, public records, and other financial institutions to verify your identity and track your credit history.
Credit history. They collect data on your debts, payment history, and credit applications by receiving reports from banks, credit card issuers, mortgage lenders, and other financial institutions.
Late payments. Lenders typically report overdue payments to credit bureaus after 30 days. Some, like student loan providers, may wait longer. Private lenders often report after 45 days, while federal loans allow up to 90 days before a delinquency is recorded.
Differences in reporting. Not all lenders report to every credit bureau, meaning your credit report may vary depending on which bureau receives the data. Even when reported to all three, updates may appear at different times due to varying processing schedules and reporting frequencies.
Public records and tax liens. The IRS doesn’t directly report tax payments or overdue balances to credit bureaus, but if unpaid taxes result in a federal tax lien, this public record is filed with the county clerk’s office, where credit bureaus can access it through third-party sources.

How Credit Bureaus Measure Your Credit Score
Credit bureaus calculate your credit score using the financial data in your credit report. They rely on two main scoring models: FICO and VantageScore. Both models assess similar factors, such as payment history and credit utilization, but use different formulas, which can result in varying scores. Since lenders may check either model, both are important in determining creditworthiness.
FICO Score Model
Payment history. 35% of your score, based on on-time, late, or missed payments.
Amounts owed. 30%, considering total debt and credit utilization. High balances can hurt your score.
Length of credit history. 15%, measuring how long your accounts have been open. A longer history helps.
New credit. 10%, factoring in recent accounts and lender inquiries. Too many can lower your score.
Credit mix. 10%, assessing different types of credit. A diverse mix can boost your score.
VantageScore Model
Payment history. 40% of your score, making on-time payments crucial.
Age and type of credit. 21%, factoring in account age and credit mix. Older, diverse accounts help your score.
Credit utilization. 20%, measuring how much credit you use. Lower usage is better.
Balances. 11%, reflecting total debt. Keeping balances low can improve your score.
New credit. 5%, considering recently opened accounts. Too many at once can hurt your score.
Available credit. 3%, looking at unused credit. More available credit can be beneficial.
Why Are Your TransUnion and Equifax Credit Scores Different?
Different scoring models. TransUnion and Equifax use proprietary models that weigh credit factors differently, leading to score variations.
Variations in reported data. Not all lenders report to every bureau, so one report may have information the other lacks.
Timing of updates. Lenders may report to different bureaus at different times, causing temporary differences in scores.
Score snapshots. Credit scores reflect a specific moment in time, so comparing scores from different dates can show discrepancies.

Which Credit Report Do Lenders Look At?
No single preferred bureau. Lenders use reports from Equifax, Experian, and TransUnion, but no bureau is universally favored over another. Each provides credit reports, scores, and identity monitoring tools.
Lender discretion. It’s often unclear which bureau’s report a lender will use, and they are not required to disclose this information. However, if a credit application is denied, federal law requires the lender to provide the main reasons, the credit score used, and details on obtaining a free copy of the report.
Differences in reports. Creditors may report to one, two, or all three bureaus, leading to slight variations in your credit reports. Checking all three periodically helps catch errors, especially before applying for a major loan.
Comprehensive evaluations. Some lenders rely on just one credit bureau, while others consider reports from multiple bureaus when making lending decisions.
Conclusion
While Equifax, TransUnion, and Experian collect similar financial data, they calculate credit scores differently. Understanding these differences can help you better manage your credit and financial health. By checking reports from all three bureaus, you gain a more complete picture of your credit standing, allowing you to make informed financial decisions.

Where can I get my credit reports?
You can access free weekly credit reports from each major bureau through AnnualCreditReport.com. Since Equifax, TransUnion, and Experian operate independently, their reports may contain different information. Reviewing all three helps ensure your personal and account details are accurate, preventing errors that could negatively affect your credit score.
What should I do if my credit report has an error?
If you find a mistake on your credit report, you can dispute it by contacting the credit bureau online, by phone, or by mail. Since credit bureaus don’t share information, you should check all three reports and correct errors with each bureau individually. Resolving inaccuracies can help protect your credit score from unnecessary damage.
How can I freeze my credit at all three bureaus?
You can place a free credit freeze with Equifax, TransUnion, and Experian to prevent fraudsters from opening accounts in your name. This won’t affect your credit score and can be lifted anytime if you need to apply for credit. Freezing your credit at each bureau separately ensures full protection.
