If you’ve ever heard the phrase “We need to check your credit,” your next question may be “What are the three credit reporting agencies?” The agencies are Equifax, Experian and TransUnion. These are the three credit reporting agencies in the United States that evaluate your creditworthiness.
Find out about how they work, what they do and what to look for in your credit report.
What Are the 3 Credit Reporting Agencies?
The three main credit reporting agencies in the United States are Experian, Equifax and TransUnion. These agencies are responsible for collecting information about your credit history through banks, various lenders and credit card companies.
With this information, they create your credit reports and update them regularly.
What Does Each Credit Reporting Agency Do?
Curious about what Equifax, Experian and TransUnion do? These agencies do all these tasks:
- Collect data. Data about your payments and credit accounts is collected.
- Create a credit report. The data generates a credit report.
- Share your credit report. When you apply for loans or try to rent an apartment, the agencies share your credit report.
- Calculate your credit scores. The agencies calculate your three-digit credit score. All three agencies will calculate for both models — FICO Score and VantageScore.
Do All 3 Credit Reporting Agencies Have the Same Information?
It is not enough to pull one credit report from one agency. Equifax, Experian and TransUnion will likely have slightly different credit reports. The difference happens because not all lenders report to all three agencies. Some lenders may report to all three, while others may report to only a couple.
When lenders make a decision to give you a loan, they will evaluate your credit report from more than one agency. This evaluation will decide whether to approve your application and what interest rate to offer you.
Key Takeaway
Want the entire picture of your credit? Review all three reports to get an accurate picture of your credit history.
How Do the 3 Credit Reporting Agencies Affect Your Credit Score?
The agencies are responsible for collecting data that determines your credit score. Your credit score is the three-digit number that determines your creditworthiness. These are the factors considered:
- Payment history
- Credit utilization
- Length of credit history
- Types of credit
- New credit inquiries
