Understanding Credit Reports: Experian, TransUnion & Equifax
A credit report is a detailed record of your borrowing history, maintained by three major bureaus: Experian, TransUnion, and Equifax. Here's what's in each report, how they differ, and how to read yours.
A credit report is a detailed record of how you've borrowed and repaid money. Three companies maintain these records in the U.S.: Experian, TransUnion, and Equifax. Your credit report is the raw data that FICO® and other scoring models use to calculate your credit score. If you want to understand or improve your score, you need to understand what's on your report.
You can check all three of your credit reports for free every week at AnnualCreditReport.com, the only site authorized by federal law for this purpose. The three bureaus permanently extended free weekly access, so there's no cost and no limit on how often you check.
This guide explains what's in a credit report, how the three bureaus differ, how to read each section, and what to do if you find errors.
The Three Major Credit Bureaus
The three major credit bureaus (also called credit reporting agencies or CRAs) are private companies that collect, store, and sell consumer credit information. They are not government agencies.
Experian
Experian is headquartered in Dublin, Ireland, with U.S. operations in Costa Mesa, California. It is publicly traded on the London Stock Exchange. Experian maintains credit files on over 220 million U.S. consumers and receives data from tens of thousands of data furnishers (creditors, lenders, and collection agencies).
Experian offers a free consumer account that includes a FICO Score 8 and monthly credit report access. They also operate Experian Boost, which allows consumers to add utility, streaming, and telecom payments to their Experian credit file.
TransUnion
TransUnion is headquartered in Chicago, Illinois, and is publicly traded on the NYSE. It maintains credit files on a similar scale to Experian. TransUnion is known for its TrueVision platform, which lenders use to make credit decisions, and SmartMove, a tenant screening product.
TransUnion provides free credit monitoring through its own website and partners with services like Credit Karma to provide free VantageScore credit scores.
Equifax
Equifax is headquartered in Atlanta, Georgia, and is publicly traded on the NYSE. It is the oldest of the three bureaus, founded in 1899.
Equifax also operates The Work Number, a subsidiary that maintains employment and income verification records used by lenders, landlords, and government agencies. As part of a 2019 data breach settlement, Equifax offers six additional free credit reports per year to U.S. consumers through AnnualCreditReport.com.
All three bureaus are regulated under the Fair Credit Reporting Act (FCRA), which governs how they collect, store, and share consumer information, and gives consumers the right to dispute errors.
What's in a Credit Report
Credit reports from all three bureaus contain similar categories of information, though the formatting differs. Here's what each section covers:
Personal Information
This section includes identifying details:
- Full legal name (and any name variations on file)
- Current and previous addresses
- Date of birth
- Social Security number
- Current and previous employers
This section does not affect your credit score. It's used to identify you and make sure the right accounts are attached to the right file. However, errors here (like an address you've never lived at or a name that isn't yours) can indicate a mixed file or identity theft.
Account Information (Tradelines)
This is the most important section of your credit report. Every credit account you have (or had) is listed as a separate "tradeline." Each tradeline includes:
Account details:
- Creditor name
- Account number (usually partially masked)
- Account type (revolving, installment, mortgage, etc.)
- Date the account was opened
- Date the account was closed (if applicable)
- Credit limit or original loan amount
- Current balance
- Monthly payment amount
Payment history:
- A month-by-month record showing whether each payment was made on time, 30 days late, 60 days late, 90+ days late, or in collections
- This history typically goes back seven years
- Payment history is the single largest factor in your FICO score (35%)
Account status:
- Open and in good standing
- Closed by consumer
- Closed by creditor
- Charged off (creditor wrote off the debt as a loss)
- In collections
Collections
Accounts that have been sent to a collection agency appear as separate entries from the original account. A collection entry includes:
- Collection agency name
- Original creditor name
- Original balance and current balance
- Date of first delinquency on the original account
- Status (open/paid)
Collections can significantly damage your score. They remain on your report for seven years from the date of first delinquency on the original account, not from the date the collection was opened.
Public Records
Since 2018, the three major bureaus only report bankruptcies in the public records section. Tax liens and civil judgments were previously included but have been removed.
- Chapter 7 bankruptcy: Remains for 10 years from the filing date
- Chapter 13 bankruptcy: Remains for 7 years from the filing date
Hard Inquiries
When you apply for credit (a credit card, loan, mortgage, or even some apartment applications), the lender requests your credit report. This creates a "hard inquiry" on your file. Each hard inquiry includes:
- Name of the company that pulled your report
- Date of the inquiry
- Type of inquiry
Hard inquiries remain on your report for two years but only affect your FICO score for the first 12 months. According to Experian, a single hard inquiry typically reduces your score by fewer than five points.
When shopping for a mortgage, auto loan, or student loan, multiple inquiries for the same type of credit within a 45-day window count as a single inquiry for FICO scoring purposes.
Soft Inquiries
Soft inquiries occur when you check your own credit, when a company pre-screens you for an offer, or when an existing creditor reviews your account. These appear on your report but are visible only to you and have zero effect on your credit score.
Why Your Three Reports May Differ
It's common for your three credit reports to show different information. This happens because:
Not all creditors report to all three bureaus. Some creditors only report to one or two bureaus. A credit card account that appears on your Experian report might not show up on your TransUnion report if that creditor doesn't report to TransUnion.
Reporting timing varies. Creditors report to each bureau on their own schedule. Your credit card issuer might report your balance to Experian on the 5th of the month and to Equifax on the 15th. If you made a payment between those dates, the two reports will show different balances.
Data entry errors differ. A misspelling of your name or an incorrect account number might appear on one bureau's file but not another's.
Collection agencies may not report universally. A collection might appear on one report but not the others, depending on which bureaus the collection agency reports to.
This is why checking all three reports matters. An error on your Equifax file won't be caught by looking only at your Experian report.
How to Read Your Credit Report
When you pull your report from AnnualCreditReport.com, here's a systematic way to review it:
Check Personal Information First
Verify your name, address, Social Security number, and employer. Look for:
- Names you don't recognize
- Addresses where you've never lived
- Employers you've never worked for
These could be data entry errors or signs of identity theft/mixed file.
Review Every Account
For each tradeline, verify:
- Is this your account? If you don't recognize it, flag it immediately.
- Is the account status correct? An open account you closed, or a closed account listed as open.
- Is the balance correct? Compare against your most recent statement.
- Is the credit limit correct? An underreported limit inflates your utilization ratio.
- Is the payment history accurate? Check for late payments you don't agree with.
- Is the date opened correct? Affects your credit age calculation.
Check Collections
For each collection entry:
- Do you recognize the debt? If not, it could be an error or identity theft.
- Is the amount correct? Collections are sometimes reported with inflated amounts.
- Check the date of first delinquency. This determines when it should fall off your report. If it's been more than seven years, dispute for removal.
- Is the original creditor listed? This helps you verify whether the debt is legitimate.
Review Inquiries
- Do you recognize every hard inquiry? Each one should correspond to a credit application you remember making.
- Are any inquiries older than two years? They should have been removed automatically.
- Any unauthorized hard inquiries? This could indicate someone applied for credit in your name.
Your Rights Under the FCRA
The Fair Credit Reporting Act gives you specific rights regarding your credit reports:
Free reports. You're entitled to a free credit report from each bureau at least once every 12 months. The bureaus currently offer free weekly access through AnnualCreditReport.com.
Dispute rights. You can dispute any information you believe is inaccurate or incomplete. The bureau must investigate within 30 days.
Notification of adverse actions. If a company denies your application based on information in your credit report, they must tell you which bureau provided the report and how to get a free copy.
Credit freeze. You can place a security freeze on your credit file at no charge. This prevents new creditors from accessing your report, which blocks most identity theft.
Fraud alerts. You can place a one-year fraud alert on your file by contacting just one bureau (they're required to notify the other two). This requires creditors to verify your identity before opening new accounts.
Opt out of pre-screened offers. You can stop receiving pre-approved credit offers by calling 1-888-5-OPTOUT or visiting optoutprescreen.com.

How Credit Reports Connect to Your FICO Score
Your FICO score is calculated entirely from the data in your credit report. There's no additional data that goes into the score. This means:
- If an error on your credit report is hurting your score, fixing the error will improve your score
- If your reports are accurate but you want a higher score, you need to change the underlying behaviors that generate the report data
- Different FICO scores can come from different bureau reports because the underlying data may differ
The five FICO scoring factors all map directly to credit report data:
- Payment history (35%): pulled from the payment status of your tradelines
- Amounts owed (30%): calculated from your current balances and credit limits
- Length of credit history (15%): derived from account open dates
- Credit mix (10%): based on the types of accounts in your tradelines
- New credit (10%): determined by recent hard inquiries and newly opened accounts

Beyond the Big Three
While Experian, TransUnion, and Equifax are the three major credit bureaus, they're not the only consumer reporting agencies. Dozens of specialty bureaus track specific types of data:
- ChexSystems tracks bank account history (bounced checks, involuntary closures)
- The Work Number (owned by Equifax) tracks employment and income verification
- LexisNexis C.L.U.E. tracks insurance claims history
- NCTUE tracks utility and telecom payment history
Under the FCRA, all consumer reporting agencies must provide you with a free report once per year upon request. If a specialty bureau's data was used to deny you a service (like a bank account), the denial notice will tell you which agency to contact for your free report.
Common Mistakes to Avoid
Don't ignore your reports. Many people never check their credit reports until they're denied for a loan. By then, errors or fraud may have been dragging down their score for months or years.
Don't confuse credit reports with credit scores. Your credit report is the raw data. Your credit score is a number calculated from that data. AnnualCreditReport.com provides free reports but not scores. For free FICO scores, see our guide to checking your score for free.
Don't pay for your reports. The three major bureaus' reports are free weekly at AnnualCreditReport.com. Don't pay a third-party site for something you can get directly at no cost.
Don't dispute accurate information. Only dispute items that are genuinely incorrect. Filing frivolous disputes wastes time and can cause the bureau to stop investigating future legitimate disputes.
Don't forget all three bureaus. An error might appear on only one report. Checking just one bureau gives you an incomplete picture.
Frequently Asked Questions
How often should I check my credit reports?
At minimum, check all three reports once per year. A better approach is to check one report every four months (rotating between bureaus) or check all three quarterly. Free weekly access at AnnualCreditReport.com makes frequent checking easy and free.
Do credit reports include my credit score?
No. The free reports from AnnualCreditReport.com include your credit history but not your credit score. To see your FICO score, use myFICO.com, Experian's free account, or check through your bank or credit card issuer.
How long do negative items stay on my credit report?
Most negative items remain for seven years from the date of first delinquency. Chapter 7 bankruptcy stays for 10 years from the filing date. Hard inquiries remain for two years. Positive information (on-time payments, open accounts in good standing) can remain indefinitely.
What should I do if I find an error on my credit report?
Dispute it directly with the credit bureau that shows the error. You can file online, by phone, or by mail. The bureau must investigate within 30 days. If the error appears on multiple reports, dispute with each bureau separately.
Can my employer see my credit report?
A current or prospective employer can pull a version of your credit report, but only with your written consent. The version they see does not include your credit score and is a modified report. You have the right to refuse, though some employers may make it a condition of employment.
What's the difference between a credit report and a credit score?
A credit report is the detailed record of your credit history maintained by the credit bureaus. A credit score is a three-digit number calculated from that report data by a scoring model like FICO or VantageScore. The report is the raw data; the score is the summary.
