Answer in brief
An adverse action notice is the letter insurers must send when information in your credit report leads to a higher rate, a lower tier or a declined application. It names the credit bureau used, lists the main reasons, and tells you how to get a free copy of the report within 60 days. Use it to find and dispute errors and to understand which factors to work on.

What the notice contains
- The action taken (higher rate, tier placement, denial).
- The credit bureau whose report was used, with contact details.
- Up to four or five key reasons the score was not higher.
- Your right to a free report copy within 60 days and to dispute inaccuracies.
What to do
- Request the free report from the named bureau.
- Check every account for errors—wrong balances, accounts that are not yours, paid items showing as unpaid.
- Dispute errors with the bureau; they must investigate within 30 days.
- If the report changes, ask your insurer to re-rate.
- Work on the listed reasons; see improving your score.
