Three-bureau basics

Your credit story isn’t stored in one national file. Three major consumer reporting agencies — Experian, Equifax, and TransUnion — each maintain a report that can differ. Bureau literacy is the foundation before you dispute, compare scores, or wonder why one site shows an account the other doesn’t.

Why three bureaus exist

Creditors choose which bureaus they report to — some report to all three, some to one or two. Inquiries, balances, and statuses can diverge because furnishers update on different schedules or because an error hit only one file. That’s normal variance, not necessarily fraud — but it’s worth reading all three when you’re doing serious file work.

What to compare

• Account names and numbers — partial matches can hide duplicates.
• Balances and credit limits — especially on revolving accounts.
• Payment history grids — late marks may not sync across bureaus.
• Date of first delinquency — relevant for collections and charge-offs.
• Hard inquiries — who pulled, and when.

Scores vs reports

A score is a snapshot calculated from a report at a moment in time. Different bureaus, different scoring models, different results — none of which are promises about a future number. Focus on the underlying trade-lines first; scores follow the file, not the other way around. See utilization without the myth for one lever you actually control.

Free reports — your right

Federal law gives you access to your reports. AnnualCreditReport.com is the authorized channel for free weekly reports from each bureau (availability rules can change — check the site for current terms). You can dispute inaccurate information with each bureau directly at no cost. NewLeaf adds structure when you want supervised software beside those rights — not instead of them.
