Understanding Auto Insurance Company Codes

Look closely at your auto insurance ID card and you'll usually find a number next to the insurer's name. That company code identifies exactly which insurance company, out of the many companies inside most insurance groups, issued your policy. Police, motor vehicle agencies and other insurers use it to confirm your coverage quickly.

NAIC company codes

The National Association of Insurance Commissioners (NAIC), the organization of state insurance regulators, gives each insurance company a numeric company code, often called the NAIC number. These are usually five digits (NAIC). A large insurance group has a different code for each of its underwriting companies, which is why two cards from the same brand can show different numbers. Many states ask for the NAIC number on insurance cards and forms. West Virginia, for example, asks for it on registration transactions and has required it on its WV-1 insurance certificates since 2014 (West Virginia Division of Motor Vehicles).

You can look up a company by name or NAIC code in the NAIC's Consumer Insurance Search, which also shows closed complaint data. It's a useful check on an insurer before you buy.

State company codes: New Jersey's three-digit codes

Some states run their own code lists. New Jersey is the best-known example: every permanent insurance ID card issued in New Jersey must show the insurer's code, as assigned by the Motor Vehicle Commission, immediately before the insurer's name (N.J.A.C. 11:3-6.3). The MVC publishes the list of insurers authorized in the state with their three-digit codes. The version updated September 3, 2026 lists about 630 codes (New Jersey Motor Vehicle Commission).

Codes are withdrawn when a company stops writing in the state or is merged into another. For example, code 903 doesn't appear in the September 2026 list. If the code on your card isn't on the current list, ask your insurer to confirm which company issued the policy and get a corrected card if needed.

Why the code matters to you

  • It confirms who actually insures you. Brands, agencies and comparison sites often sell policies from a group's subsidiaries. The code tells you which company is on the hook for claims, and which one to research.
  • It helps spot fake cards. A card with no code, or with a code that doesn't match the insurer named, is a warning sign, whether you're checking your own card after buying through an unfamiliar seller or another driver's card after a crash.
  • It speeds up paperwork such as registrations, accident reports and claims between insurers.

How to find a company from its code

  1. For a five-digit NAIC number, use the NAIC Consumer Insurance Search.
  2. For a state code, check the list published by the state motor vehicle agency or department of insurance, such as New Jersey MVC's “Insurance Company Codes.”
  3. Confirm the company is licensed in your state through your state department of insurance, and check its complaint record while you're there.
