Most people meet Credco in one of two places: as an unfamiliar hard inquiry reading CoreLogic Credco during a mortgage or auto application, or in the fine print of a denial letter naming the company that supplied the credit report. Either way, the question is the same — who is this, and why do they have my credit file?
What Credco is
Credco — formally CoreLogic Credco — is a credit reporting company that serves lenders. Its own consumer assistance page describes it as a consumer reporting agency that resells consumer report information rather than maintaining its own database, specializing in merged credit reports that combine data from Equifax, Experian and TransUnion. It appears on Fannie Mae’s list of approved credit information providers — the companies mortgage lenders order reports through when they process an application. It does not make lending decisions. It gathers your information from the three national bureaus, assembles it into a single merged report, and sells that report to the bank, mortgage company or dealer that ordered it.
Why Credco is on your credit report
When a lender orders your credit through Credco, the pull is recorded on your bureau files under Credco’s name, sometimes alongside the lender’s. That is why an application with a bank you recognize can produce an inquiry from a company you have never heard of. If you applied for a mortgage or a car loan recently, a Credco inquiry is usually that application. If you have not applied for anything, an inquiry you do not recognize is worth taking seriously — it can be a sign of a mixed file or identity theft, and you have the right to know who pulled your file and why.
The report your lender saw is not the report you see
The merged report Credco assembles for a lender is not identical to the file you pull from the bureaus, and mortgage lenders score with different models than consumer apps use. That gap matters when something goes wrong: an account that is not yours, a paid-off debt still showing a balance, or another person’s record merged into your file can sit in the lender’s version and cost you an approval you should have had.
How to dispute an error on a Credco report
Credco’s consumer relations department handles report requests and disputes at (800) 637-2422, Monday through Friday, 6 a.m. to 5 p.m. Pacific Time, per its consumer assistance page — a request needs your full name, Social Security number, current address, date of birth and signature, with matching government-issued ID and a recent proof of address. Identity theft reports go to P.O. Box 509124, San Diego, CA 92150. Because Credco assembles bureau data, the error usually also lives at Equifax, Experian or TransUnion, so a complete dispute goes to the source bureau as well. Companies that assemble and resell credit reports are consumer reporting agencies under the Fair Credit Reporting Act, with their own accuracy and dispute-handling duties — a dispute they ignore or a report they will not correct is not a dead end.
When a report error costs you the mortgage
If an inaccurate report cost you a loan approval or a better rate, that denial letter is not just bad news — it is evidence. The FCRA lets consumers recover actual damages, and in the right case statutory and punitive damages, from the companies responsible for inaccurate reporting. The deadlines run from discovery, so a denial letter naming Credco is a document to keep, not discard. Our page on suing a mortgage company for an FCRA violation covers how these cases work, and if another person’s information is in your file, start with mixed credit files.
What it costs
The FCRA is a fee-shifting statute: when a consumer wins, the company pays the attorney’s fees. You pay nothing unless we win.
Where your situation fits
Credco is one of a small group of companies that pull and merge credit reports for mortgage lenders — the same family as Factual Data. If the name on your report or denial letter is one of these, the analysis is the same: get the report, find the error, and hold both the reseller and the source bureau to the statute. Our FCRA attorney page covers how these cases work.
