What Insurance company uses Policy?

Answer 1

The question does not make sense as written. All insurance companies use "policies", because that is the name for the written contract between the insured and the insurer.

If you are referring to a policy number that is assigned when a policy is issued, the question cannot be readily answered. This is because all insurers have distinct numbering systems for their policies.

Finally, numbers also appear on policies that are called "Form numbers". This relates to the standard policy language that is inserted into the policy to state the terms of the insuring agreement; often, different insurers will use essentially the same language, especially with respect for formal provision of the policy. What sometimes differs in these is the precise form number used, although as between insurers, the language is essentially the same.

In conclusion, without knowing more, your question cannot be answered as phrased.

I think the question relates to CSC's 'POLISY' general insurance administration system.
