The Three Nationwide Credit Bureaus: Equifax, Experian, and TransUnion
The three nationwide credit bureaus are Equifax, Experian, and TransUnion. They are credit reporting agencies, not lenders or government bodies. Each gathers information from creditors and public records, builds a consumer credit file, and supplies credit reports to lenders, landlords, and others with a permissible purpose under federal law.
This guide is general educational information for U.S. readers. It is not financial advice and does not describe your individual credit file. Figures such as score ranges and timeline estimates are typical examples, not promises.
Key takeaways
- Equifax, Experian, and TransUnion are the three nationwide credit reporting agencies, and each keeps its own separate file on a consumer.
- Credit bureaus compile and supply data; they do not approve applications, set interest rates, or lend money.
- The Fair Credit Reporting Act gives consumers the right to a free credit report from each nationwide agency every 12 months, and the three agencies currently provide free reports weekly through AnnualCreditReport.com.
- Under the FCRA, an agency generally must investigate a dispute within 30 days, with the period extended to 45 days if the consumer supplies additional information during the initial 30-day window.
- Most credit scores, including FICO and VantageScore, use a range of 300 to 850, and scores are calculated from the contents of credit files rather than set by the bureaus.
- A security freeze is free to place, temporarily lift, or remove under federal law, and an initial fraud alert lasts 1 year while an extended fraud alert lasts 7 years.
The three nationwide credit bureaus are Equifax, Experian, and TransUnion. Each is a credit reporting agency — a private company that gathers information about how consumers use credit and organizes it into individual credit files. They are not lenders and not government agencies, though their activity is regulated by federal law.
What "credit bureau" means
"Credit bureau" is the everyday label for a consumer reporting agency that specializes in credit information. The term appears far more often in ordinary conversation than in the statute that governs the industry. Federal law refers to these companies as consumer reporting agencies, and the largest ones — which operate nationally rather than in a single state or region — are described as nationwide credit reporting agencies.
A credit bureau does not decide who is approved for a loan, a card, or a rental. Lenders, landlords, insurers, employers, and utility providers with a permissible purpose under federal law can request a report, then apply their own criteria in their own underwriting process. The agency's role is to compile and supply information.
The three nationwide credit reporting agencies
| Agency | Type of company | What it maintains |
|---|---|---|
| Equifax | Nationwide credit reporting agency | An independent credit file on each consumer, built from creditor data and public records |
| Experian | Nationwide credit reporting agency | An independently compiled credit file using data received from furnishers |
| TransUnion | Nationwide credit reporting agency | An independently compiled credit file using data received from furnishers |
Each company maintains its own database. There is no shared national master file. When a creditor reports an account, it may send that information to one, two, or all three agencies. Because coverage varies by lender, the three files on the same person can differ in meaningful ways. Together these three files form the core of a consumer's credit profile.
Why the three reports can differ
Most differences come from reporting patterns rather than mistakes. A credit union that furnishes data to only two agencies will appear on two files and be absent from the third. Collection accounts sold between debt buyers can be reported with different balances at different agencies. Credit limits are sometimes reported inconsistently. Because the information is not identical across agencies, a file from one agency does not represent what the other two contain.
What credit bureaus collect
- Identifying details such as name, current and past addresses, and date of birth
- Account information from creditors, including balances, credit limits, and payment status
- Collection accounts and, where applicable, public record items such as bankruptcies
- Inquiry records generated when a party with a permissible purpose requests a file
Retention periods are set by law rather than by the agencies. Most negative information, including late payments, stays on a credit report for 7 years. A Chapter 7 bankruptcy stays for 10 years, while a Chapter 13 bankruptcy stays for 7 years. Hard inquiries typically remain on a credit report for 2 years.
What credit bureaus do not do
- They do not issue credit cards, loans, or mortgages.
- They do not set interest rates or approve applications.
- They do not build the scoring models themselves; model developers publish the formulas, and scores are calculated from file data.
- They are not government agencies and are not funded by taxpayers.
Who supplies the data
Credit files are assembled from three broad streams. Data furnishers — banks, credit unions, card issuers, auto lenders, student loan servicers, and collection agencies — report account activity, usually monthly. Public record sources supply bankruptcy filings and, in some states, other court records where reporting is permitted. Inquiry records are created when a lender or another permitted party requests a file.
If a furnisher reports information that is inaccurate or incomplete, a dispute can be filed with the agency that holds the item, and the agency then contacts the furnisher for verification. The credit reports hub collects related pages on report access and file accuracy.
Consumer rights under the Fair Credit Reporting Act
The FCRA (15 U.S.C. section 1681) was enacted in 1970 and amended by the Fair and Accurate Credit Transactions Act in 2003. It provides the right to a free credit report from each nationwide agency every 12 months, and the three agencies currently provide free reports weekly through AnnualCreditReport.com.
The law also sets dispute timelines. Under the FCRA, a credit reporting agency generally must investigate a dispute within 30 days; the period can extend to 45 days if the consumer provides additional information during the initial 30-day period. Two provisions address identity theft specifically: section 605A (15 U.S.C. section 1681c-1) covers fraud alerts, and section 605B (15 U.S.C. section 1681c-2) covers blocking of information that resulted from identity theft.
The Consumer Financial Protection Bureau, created by the Dodd-Frank Act in 2010 and operating since 2011, has supervisory authority over the consumer reporting market. The Federal Reserve publishes aggregate consumer credit statistics, including its G.19 release on total outstanding consumer credit; that data describes the market as a whole rather than any individual file.
How file data becomes a credit score
A credit score is a numerical summary calculated from the contents of a credit file. Most credit scores, including FICO and VantageScore, use a range of 300 to 850. FICO publishes approximate weights for the factors in its model:
| FICO factor | Approximate weight |
|---|---|
| Payment history | 35% |
| Amounts owed | 30% |
| Length of credit history | 15% |
| New credit | 10% |
| Credit mix | 10% |
VantageScore uses its own factor weighting and does not publish fixed percentages. Because scores are derived from file data, differences among the three agencies' files can produce different scores for the same consumer on the same day. The guide on how credit scores are calculated describes the full picture, while FICO versus VantageScore compares the two model families. Individual factors are covered in the guides on payment history, credit utilization, and length of credit history.
Fraud alerts, security freezes, and identity theft
Two protections are arranged directly with each nationwide agency. A fraud alert asks lenders to take reasonable steps to verify identity before extending credit; an initial fraud alert lasts 1 year, and an extended fraud alert lasts 7 years. A security freeze restricts access to a credit file; under federal law a freeze is free to place, temporarily lift, or remove. The credit freeze page covers how the process works, and the credit lock page explains how locks differ from freezes.
When identity is stolen, the incident can be reported at IdentityTheft.gov and to the IRS using Form 14039. An identity theft report supports a request to block fraudulent information under FCRA section 605B, and the identity theft hub collects related pages on alerts, freezes, and documentation.
Reading the three files together
Each agency builds its own file, so no single report shows everything a lender might see. Comparing files side by side commonly reveals:
- Accounts that appear at one or two agencies but not all three
- Different balances or credit limits for the same account
- Duplicate collection entries
- Inquiries from lenders that appear on only one file
- Name or address variations that affect how records are matched
Regular review of file changes is the focus of credit monitoring, and the credit check page explains what a lender sees when a file is pulled.
Common misunderstandings
The bureaus are government agencies
They are private companies. Each publishes consumer education material of its own, such as the Equifax credit education pages, alongside material published by federal regulators.
The three bureaus share one file
They are competitors that maintain separate databases and receive data from furnishers independently, which is why one report cannot be substituted for another.
There is one official credit score
Scores come from scoring models built by different developers, and a single bureau may distribute several models. No single number is used by every lender.
A credit bureau decides who gets credit
Approval decisions belong to the lender, landlord, or insurer that requested the file. The agency supplies the data, and the decision-maker applies its own standards. Details on how the 300 to 850 scale is divided appear in the credit score ranges guide, with additional context at the credit score hub.

Frequently asked questions
What are the three nationwide credit bureaus?
The three nationwide credit reporting agencies are Equifax, Experian, and TransUnion. Each is a private consumer reporting agency that maintains its own file on a consumer and supplies credit reports to lenders, landlords, employers, and insurers that have a permissible purpose under the Fair Credit Reporting Act.
Are credit bureaus the same thing as credit reporting agencies?
Yes. "Credit bureau" is the common label, while federal law uses the term consumer reporting agency. The largest companies operating across the whole country are known as nationwide credit reporting agencies.
Why are my three credit reports different?
Each agency collects data independently, and creditors may furnish information to one, two, or all three agencies. That means balances, credit limits, collection accounts, and inquiries can appear differently across the three files, and no single report shows everything a lender might see.
Do the three credit bureaus each produce the same credit score?
No. Credit scores are calculated from file data using models built by developers such as FICO and VantageScore. Most credit scores use a range of 300 to 850, and a bureau may distribute several models, so the same consumer can have different scores depending on the file and model used.
How often can I get a free credit report from each bureau?
The FCRA gives consumers the right to a free credit report from each nationwide agency every 12 months, and the three agencies currently provide free reports weekly through AnnualCreditReport.com.
Can a credit bureau remove accurate information from a report?
Agencies must investigate disputed information and delete or correct items shown to be inaccurate or incomplete. Accurate information remains on the report for the retention period set by law, such as 7 years for most negative information and 10 years for a Chapter 7 bankruptcy.
