Understanding Credit Bureau Disputes: Why and When to File

Credit bureaus--Equifax, TransUnion, and Experian--compile your credit reports, which lenders use to calculate FICO scores. Errors on these reports can tank your score, leading to denied loans or high interest rates. According to FTC and CFPB studies, 20-40% of reports contain errors, like inaccurate personal info, outdated collections, or unauthorized hard inquiries.

Common error types:

• Inaccurate information: Wrong addresses, employment, or balances.
• Collections and medical debt: Often disputable if paid or invalid.
• Hard inquiries: Unauthorized pulls from creditors.
• Identity theft: Fraudulent accounts.
• Old accounts: Items over 7 years that should be removed.

Disputing fixes these under the Fair Credit Reporting Act (FCRA), which mandates free weekly reports via AnnualCreditReport.com. A mini case study: Sarah, an identity theft victim, disputed fraudulent accounts with proof from an FTC Identity Theft Report. All three bureaus deleted them within 35 days, raising her FICO by 85 points and securing a mortgage.

File a dispute if you spot errors impacting your score--it's free and empowers DIY credit repair.
