What auto insurance carrier uses policy numbers that start with auto?

Answer 1

It's very difficult to tell what company uses certain prefixes on their policy numbers. Many companies have multiple prefixes and some companies use the same as other companies. They also wary from state to state. If the insurance company name is not listed on accident report contact the policy officer and he may have it in his notes but not on the accident report. Otherwise start calling agents in the area where the person lives.
