Insurance companies don’t use a score provided by one of the big credit bureaus. They create their own “insurance score” using their own criteria. It’s a secret formula; they won’t tell you how your score is computed. In many states, insurance companies aren’t even required to tell customers their credit history was used to set their premium.
“The secrecy behind this credit scoring is part of what makes it so inherently unfair,” Kreidler says. “No two companies use it the same way and when consumers ask, they can’t get a straight answer on how to get a better score.”
