The policy number on an insurance card is a unique code associated with the insurance plan. It is used by the insurance company to track and process insurance claims and costs. The policy number may also be referred to as a subscriber ID or member ID number. Typically, the policy number can be found on the front of the insurance card and may be marked as "Policy #" or "Policy ID". If you are unable to locate your policy number, you can reach out to your insurance provider for assistance. The policy number is different from the group plan number, which is a code assigned to your employers insurance plan if you have insurance coverage through an employer. The group plan number helps insurance companies identify the benefits included in your employers plan and process claims effectively. The insurance card may also include other information such as your name, your spouses or parents name if you are covered under their plan, your home address, and contact information for the insurance company.
