The fields a checker can verify by looking at you
Most of the data on a license cannot be checked against the person standing there. A bouncer cannot confirm your address or your license number by looking at you. But height, weight, eye color, and hair color are different. Those are the fields that describe your body, and they are the fields a checker can compare directly to the person holding the card. That makes them some of the most important details to get right, and some of the easiest to get wrong by being careless or by treating them as filler.
Getting these fields to match the real person is the same project as keeping your look matched to the photo. The photo and the physical description should describe the same individual, and so should you on the night.
Height: format and honesty
Height is printed in feet and inches, often in a compact form like 5-09 or 509 for five feet nine inches. The format varies slightly by state, but the principle does not: the number should be your actual height. A checker who suspects an ID will sometimes glance from the card to the person and back, and a listed height that is two or three inches off from the obvious reality of the person in front of them is a flag. Round to your real height, not an aspirational one.
Weight: a range, not a precise science
Weight is the most forgiving of these fields because it genuinely changes over time and nobody expects a card to be current to the pound. Still, it should be plausible for your build and roughly consistent with your appearance. A weight that is wildly inconsistent with the person, far too low for a tall, broad frame or far too high for a slight one, draws the same kind of attention as a bad height. Pick a number that fits you within a reasonable range.
Eye color: standardized codes
Eye color is usually printed as a three-letter code. The common ones are BRO for brown, BLU for blue, GRN for green, HAZ for hazel, GRY for gray, and BLK for black. These codes are fairly consistent across states because they follow the same national design guidance. The rule here is obvious but easy to ignore: the code should match your actual eye color, because this is one of the few things a checker can confirm by looking up from the card.
Hair color: also coded, also visible
Hair color follows a similar three-letter pattern, such as BRO for brown, BLN for blond, BLK for black, RED for red, and GRY for gray. Hair is trickier than eyes because people change it, dye it, or lose it. The safest approach is to list your natural or current color and to be aware that a dramatic mismatch, a card that says blond on a person with jet-black hair, is the kind of contrast that registers instantly. Hair can be explained more easily than eye color, but it is still better to keep it consistent.
Why the codes are standardized
The three-letter color codes come from the same national card design guidance that shapes the rest of the license layout. That standardization is helpful, because it means the codes look right to scanners and to people who read cards regularly. Using the correct code, in the correct format, is part of making the card read as genuine rather than as something assembled from guesswork. The closely related coding on the driving side is covered in what the codes and restrictions mean.
Treat these fields as a description of a real person
The simplest way to think about height, weight, eye color, and hair color is that together they form a physical description that a stranger could use to pick you out of a crowd. If that description matches the person presenting the card, the fields do their job quietly. If it does not, they become the reason a routine check turns into a longer one. Fill them in as an honest description of yourself, and verify them as part of the same final review the ordering checklist recommends before anything is finalized.
Frequently Asked Questions
How is height shown on a license?
Height is printed in feet and inches, often in a compact form such as 5-09 or 509 for five feet nine inches. The exact format varies by state, but it should reflect your actual height.
How exact does the weight need to be?
Weight is the most forgiving field because it changes over time and is not expected to be current to the pound. It should still be plausible for your build and roughly match your appearance.
What are the eye color codes on an ID?
Common three-letter codes include BRO for brown, BLU for blue, GRN for green, HAZ for hazel, GRY for gray, and BLK for black. They follow national design guidance and are fairly consistent across states.
What if I have dyed hair?
List your natural or current color and keep it reasonable. Hair changes are common and easier to explain than eye color, but a dramatic mismatch between the card and your appearance still draws attention.
Why do these fields matter more than others?
Because they describe your body, a checker can compare them directly to the person holding the card. Unlike an address or a license number, height, weight, and eye color can be verified just by looking up.
Are the color codes the same in every state?
The three-letter color codes are largely consistent across states because they follow shared national design guidance, though minor formatting differences exist. Matching your actual coloring is what matters most.
