It's not really possible to determine which insurance company is which by the policy number or the prefix. They differ greatly and many use the same prefix. The letter "P" start many personal auto policies with lots of companies just due to the letter "P" starting personal. Lots use CA for commercial auto. Sometimes the starting letter has to do with the state the policy is in or really has nothing at all to do with anything.

Probably lots of insurance companies use FL to start policy numbers in Florida. Doesn't it make sense. Insurance companies can use whatever they like to make up their policy numbers. Some companies may use the same prefixes or suffixes as other companies do. FL starting a policy number from Florida may include all Assigned Risk policies which may be assigned to all insurance companies doing business in Florida. It is impossible to tell the company by the Prefix. Many use PA to start all their Personal Auto Policies for instance. CA starts many companies Commercial Auto Policies. You see the way it works.
