Each collects information from creditors and other sources, compiles it into consumer reports, and provides reports to users with a legally permitted purpose. They share this basic role; none is assigned a universal specialty such as mortgages or credit cards. Because they are separate companies and may receive different information, your report at one bureau can differ from your reports at the other two.
What the three credit bureaus do
A credit bureau—also called a consumer reporting company or consumer reporting agency—organizes information about consumers into files and produces consumer reports. Lenders and other businesses may request a report when they have a legally permitted purpose, such as evaluating a credit application. The Consumer Financial Protection Bureau (CFPB) identifies Equifax, Experian, and TransUnion as the three nationwide consumer reporting companies. Other specialty reporting companies handle reports for areas such as tenant or employment screening; the CFPB maintains a directory of consumer reporting companies.
Equifax
Equifax is one of the three nationwide companies that collects and organizes consumer information into credit reports. Its role is not limited to a particular lender, loan type, or industry.
Experian
Experian performs the same broad nationwide reporting function: it maintains consumer-file information and provides reports to authorized users. If you are dealing with a rental or employment screening report, identify the company that prepared that specific report rather than assuming Experian or another nationwide credit bureau did so.

TransUnion
TransUnion is the third nationwide company and likewise compiles consumer information into reports. Its overview of credit reporting agencies explains the distinction between a report and a score.
The shared function matters more than supposed bureau specialties. The available official guidance does not establish that one bureau is always used for mortgages, another for credit cards, or that any lender always checks the same bureau.

What a credit report contains—and how it differs from a score
A credit report is a file of information; a credit score is a number calculated from report information using a scoring model. A score is not the report itself, and the score shown by one bureau or service should not be treated as a universal score used by every lender.
Reports commonly include identifying details, credit accounts, payment history, balances or credit limits, and inquiries. A score depends both on the information available and on the model applied to it. Models can weigh factors differently. For example, TransUnion says the score it provides is a VantageScore 3.0; another service or lender may use a different model or version.
Why your reports can differ
Creditors may send updates to one, two, or all three nationwide companies, and they may not send information at the same time. As a result, an account, balance, payment update, or inquiry can appear in one report but not another, or appear with different timing. The CFPB and TransUnion explain that reports may not match; see TransUnion’s guidance on comparing reports.
Differences are not automatically errors. Compare the reports themselves and check whether the underlying entries are accurate. Useful comparison points include:
Rank #4
- Coverage: Which accounts and creditors appear in each file?
- Accuracy: Are your identifying details, account status, balances, payment history, and inquiries correct?
- Timing: Do report dates or a creditor’s update schedule explain a difference?
There is no established universal ranking of the three bureaus for completeness, reliability, or usefulness. A report that differs from another may reflect different information furnished to each company, not a bureau-wide quality ranking.
How to get and review all three reports
Reviewing each report lets you catch information that is missing or different in another bureau’s file. The CFPB says consumers are entitled to one free report from each nationwide company every twelve months through AnnualCreditReport.com. The CFPB and TransUnion also report that free weekly reports are currently available through that same official site. Access rules can change, so check current details there. The CFPB additionally says U.S. consumers may request up to six additional Equifax reports in a twelve-month period through December 2026, beyond reports otherwise available under federal law; that time-limited entitlement should not be assumed to continue after that date. See the CFPB’s consumer reporting company guidance.

If information is inaccurate or incomplete, you can dispute it with the reporting company and with the company that supplied it, such as a lender. The CFPB says the investigation is free; you do not need to pay a credit-repair company to submit a dispute. Its dispute guidance, last reviewed September 2, 2026, recommends explaining what is wrong and why, and including copies of relevant evidence.
- Identify the error. Record which report contains it and describe the specific account or detail that is wrong or incomplete.
- Contact both parties. Submit a dispute to the bureau showing the error and to the furnisher that supplied the information. Use each company’s current dispute instructions.
- Include supporting material. Send copies, not irreplaceable originals, of documents that help establish the correct information. Keep copies of your dispute and attachments.
- Check each affected report. If the same error appears at more than one bureau, submit a separate dispute to each bureau showing it; dispute processes are agency-specific.
What to do if identity theft may be involved
Review your reports for unfamiliar accounts or other suspicious entries. The CFPB advises considering a security freeze if you are concerned about identity theft. Nationwide reporting companies must freeze and unfreeze a file on request without charge, according to the CFPB’s consumer reporting companies list. A freeze restricts third-party access to a credit file, but it should not be treated as a guarantee against every form of identity theft or as a substitute for reporting suspected identity theft. The CFPB points consumers to IdentityTheft.gov for federal identity-theft recovery guidance.
