If a life, health, disability, critical illness, or long-term care insurer asked unexpected questions, rated you up, or turned you down, one input may have been a file you have never seen: your MIB Consumer File. MIB, Inc. is a consumer reporting agency serving the insurance industry, its file about you is governed by the Fair Credit Reporting Act, and when that file is wrong, you have the same federal rights you would have against a credit bureau.
What MIB is
The CFPB’s consumer reporting company list places MIB in its medical category: a subsidiary of MIB Group, Inc. that collects information about medical conditions and hazardous avocations from member insurance companies, and reports it — with your authorization — to member life and health insurers underwriting individual life, health, disability income, critical illness, and long-term care policies. MIB’s own materials describe the file the same way: a contributory database maintained by its member companies, populated when you authorize an insurer to report, and cross-checked when you apply so carriers can compare your new application against what members reported before.
How the file is used — and its limit
When you apply for individual coverage, the insurer checks your MIB file against your application. A code that contradicts what you disclosed invites scrutiny; per MIB’s own consumer pages, carriers are not enabled to make underwriting decisions based on your MIB Consumer File without further investigation. But the file is still an input to the decision — and a code that is wrong, outdated, or belongs to someone else becomes a problem you cannot see and did not cause. In the twelve months ending August 2026, the CFPB’s public complaint database shows 270 complaints naming MIB Group, Inc.
The errors that matter
A file that generally exists only if you applied for individual coverage in recent years can still carry someone else’s information — a relative with a similar name, a member company’s data-entry mistake — the same matching failure that produces a mixed credit file. A condition you never had, coded from a misread application. A resolved condition reported in a way that reads as current. Each is a concrete accuracy problem in a consumer report that shaped your coverage or your premium. MIB is one of two specialty bureaus that matter in insurance underwriting — the other, Milliman IntelliScript, reports your prescription purchase history — and an error at either one follows you from application to application.
Your rights: the file is free, and the dispute is federal law
Per the CFPB’s listing, you can request a free copy of your MIB Consumer File once every twelve months — by phone at 866-692-6901 or by mail at MIB, Inc., 50 Braintree Hill Park, Suite 400, Braintree, MA 02184-8734 — and companies required to provide free annual reports must deliver them within fifteen days of the request. If anything is inaccurate or incomplete, you can dispute it, and the FCRA requires a reasonable investigation, free of charge, with correction of anything that cannot be verified. Our credit dispute letter guide applies to specialty bureaus like this one.
When it becomes a legal claim
If coverage was denied or priced up over file information that was not yours or not accurate, and a proper dispute did not fix it, the FCRA provides actual damages — the coverage you lost, the premium difference, the time — statutory and punitive damages for willful violations, and attorney’s fees, which is why we handle these cases on contingency. Specialty bureaus outside the big three are still consumer reporting agencies, from LexisNexis to SageStream to this one — and the law reaches all of them.
