What Information Is on an Insurance Card?

The contents of insurance cards differ depending on the insurance provider, but they generally show information about the names of policyholders and insurers, group numbers, account numbers, names of plans, and contact details of the insurers, reports CBS Denver. Some health insurance cards show the required copayment amount to pay when consulting a doctor. Car insurance cards contain information about the types of vehicles, policy numbers and effective dates, states Geico.

Private insurance companies and the Department of Health in each state issue health insurance cards to policyholders, according to CBS Denver. Policyholders who visit new doctors for the first time should bring their insurance cards with them, as health care providers require insurance information during the initial appointment. Health care providers keep photocopies of insurance cards. Policyholders who buy prescription medications at pharmacies also need to show their insurance cards.

Car insurance policyholders may use their cards to register their vehicles and show the cards as proof of insurance when necessary, notes Geico. Some insurance cards also contain mailing addresses, websites or contact numbers of the insurers, states Bolt Insurance Agency. It's a good idea to keep an insurance card in a secure, easily accessible area, such as a drawer, or keep it safely in a wallet, as the information it contains is essential for purposes such as filing claims.
