In this explainer

Regulators specify the insurance card down to the quarter inch, the point size and the colour of the ink. Then they describe the policy number itself as, and this is the actual wording, alphanumeric.

There is no national rule

Nobody can tell you how many digits your policy number has, and that is not because they have not looked. There is no national rule about what goes on a car insurance card. Every requirement is set state by state, and the lists do not match each other.

They specify the card, not the number

Here is what makes it strange. The rules are extremely specific, just not about the thing you are looking for. Florida fixes the paper card at three and a half inches by two and a quarter inches. Texas requires at least ten point type. California requires the ink to be black.

And then, the actual wording

Then, in the same enumerated list, Florida describes the policy number like this. Alphanumeric assigned policy number, self insurance license, or contract number. No length. No prefix. No pattern. That is the whole specification.

Five states, five different cards

Put five states side by side and the cards are not even the same object. Illinois sets a minimum of three inches by two and an eighth with no maximum, on twenty pound stock, in eight point upper case. Ohio specifies nothing physical at all and lets the card be paper, plastic or electronic. A card that satisfies Florida cannot satisfy Illinois.

The five digit NAIC number is one state's rule

You will read everywhere that the short code by the insurer's name is a five digit NAIC number. That is California's rule, quoted correctly, and it is not a fact about cards. Illinois requires an NAIC code and never says how long. Florida requires its own state company number instead. Texas and Ohio require no company code at all.

Rule out the VIN

So find it by elimination, because the other numbers do have a shape. Federal rules say each VIN shall consist of seventeen characters, with a check digit in position nine, and no letter I, O or Q anywhere. If a string is seventeen characters long and passes that checksum, it is your vehicle, not your policy.

It can be missing entirely

And one regulator says the number may not be there at all. Illinois, verbatim. Temporary insurance cards are not required to have the policy number but shall contain all other required information. If you are holding a temporary card, you may not be missing anything.

On a health card it is not called that

One more, because half the people asking this are holding a health card. Federal law requires exactly three things on one. The deductible, the out of pocket maximum, and a phone number and website. An identifier is not on the list. What the clinic wants is your member or subscriber I D. The full breakdown is on Dreamy Leads dot com.

Frequently Asked Questions

How many digits is a policy number?

There is no fixed number. No federal rule governs what goes on a car insurance card, and the state rules that do exist specify the card without specifying the number. Florida's rule describes the field as an “alphanumeric assigned policy number, self-insurance license, or contract number,” Texas lists it simply as “the policy number,” and California as “the policy number issued for the policy.”

Is the policy number the same as the VIN?

No. Federal rules fix the VIN at exactly 17 characters, drawn from the letters A–Z excluding I, O and Q plus the digits 0–9, with a check digit in position nine. A policy number has no such format and carries no check digit.

What is the NAIC number on my insurance card?

It identifies the insurance company, not your policy, and whether it appears depends on the state. California's rule requires “the five-digit National Association of Insurance Commissioners (NAIC) Number.” Illinois requires an NAIC company code without stating a length, Florida requires its own state company number instead, and Texas and Ohio require no company identifier at all.
