DD stands for "Designated Driver" on some state licenses, but most commonly it indicates a donor designation

The letters DD on your driver's license most often mean you have registered as an organ and tissue donor. When you see DD printed on your license, it signals to emergency responders and medical personnel that you have consented to donate your organs, eyes, or tissue if you die. This is the interpretation used by the majority of U.S. states.

A smaller number of states use DD to mark a Designated Driver license class, which is a voluntary program that identifies the holder as someone who has committed to not drinking alcohol while driving. However, the donor designation is far more common across state DMVs.

The exact placement and appearance of DD varies by state. Some states print it directly on the front of the license near your photo or name. Others place it on the back. A few states use different symbols or abbreviations altogether — for instance, some use a heart symbol or the word "Donor" instead of the letters DD.

Key Takeaways

  • DD on your driver's license almost always means you are registered as an organ and tissue donor, not that you are a designated driver.
  • The donor designation is visible to emergency medical personnel and helps them understand your wishes if you become unable to communicate.
  • You can add, remove, or change your donor status through your state's DMV, usually at the same time you renew or replace your license.
  • Each state manages its own donor registry, so the rules and how DD appears on your license depend on where you live.

How the donor designation gets on your license

When you explore for a new driver's license or renew an existing one, your state's DMV will ask whether you want to register as an organ and tissue donor. This question typically appears on the process form or on a screen if you are renewing online. You choose yes or no at that moment.

If you say yes, the DMV adds the DD marking to your license and registers you in your state's donor registry. This registry is separate from your license itself — the license is just a visible indicator that you have made this choice. The actual registry is what hospitals and transplant coordinators check when they need to confirm your wishes.

You do not need to do anything else after that. The DD marking remains on your license until you renew it, and your donor status stays in the registry unless you actively change it.

Removing or changing your donor status

If you registered as a donor but have changed your mind, you can remove the DD marking from your license. The process depends on your state, but most DMVs let you change your donor status when you renew your license, or you can request a change in person at a DMV office without waiting for renewal.

Some states also allow you to register or change your donor status through their online portal, separate from the DMV. Your state's DMV website will list the specific methods available where you live. A few states maintain a separate donor registry that you can access directly, independent of your license.

Keep in mind that removing DD from your license does not automatically remove you from your state's donor registry — you may need to take a separate step to opt out of the registry itself. Contact your state DMV or check their website to understand what happens after you remove the marking from your license.

What happens when emergency responders see DD

If you are in a life-threatening situation and cannot communicate your wishes, paramedics and emergency room staff will look at your driver's license. When they see the DD marking, they know you have registered as a donor and will follow the protocols for potential organ donation.

This does not mean they will stop trying to save your life. The donor designation only becomes relevant if you are pronounced dead and your family or medical team determines that organ donation is possible. Emergency responders prioritize keeping you alive; the donor status is information they use only if that is no longer possible.

Your family members can also see the DD marking on your license, which can help them understand your wishes during a difficult time. This is one reason many people choose to register — it makes their decision clear without requiring a separate conversation.

The difference between DD and other donor markings

Not all states use DD to mark donors. Some states print the word "Donor" on the license instead. Others use a heart symbol, a special color, or a different abbreviation. A few states do not mark the license at all but maintain a separate registry that hospitals can check.

If you move to a new state, your old license's DD marking will not transfer. You will need to renew your license in your new state and register as a donor again through that state's DMV. Each state manages its own donor registry and license design independently.

If you are unsure what marking your state uses or whether you are currently registered, check your state's DMV website or call your local DMV office. They can tell you what the markings mean in your state and help you update your status if needed.

Designated Driver programs and DD

A small number of states have created voluntary Designated Driver license programs, and some of these programs also use the letters DD. In these programs, a driver can voluntarily register as someone who commits to not consuming alcohol while driving. The license marking serves as a public commitment and sometimes qualifies the driver for insurance discounts.

These programs are much less common than the donor designation, and they exist in only a handful of states. If you live in a state with a Designated Driver program, your DMV will make clear during the license process which DD marking you are choosing — donor registration or the Designated Driver program.

To find out whether your state has a Designated Driver program, check your state DMV's website or ask at your local DMV office. Most states do not have this program, so the DD on your license almost certainly refers to organ donation.

Frequently Asked Questions

Can I change my donor status without renewing my license?

Yes, in most states. You can visit your local DMV office and request a status change without renewing your license. Some states also allow you to change your donor status online through the DMV website or through a separate state donor registry. Check your state's DMV website for the specific options available where you live.

Does being a registered donor cost money?

No. Registering as an organ and tissue donor is free. There are no fees to add the DD marking to your license or to register in your state's donor registry. Some states charge a fee to replace your license if you want the new marking when ready rather than waiting for renewal, but the donor registration itself is always free.

If I register as a donor, will hospitals let me die to harvest my organs?

No. Hospitals and emergency responders are required by law to try to save your life regardless of your donor status. Organ donation is only considered after you have been pronounced dead by a physician. Your donor status does not change the medical care you receive while alive.

What if my family disagrees with my donor registration?

Your registered choice is legally binding in most states, but many hospitals will still contact your family to discuss the decision. If you want to make sure your wishes are followed, tell your family members about your donor status and explain why you made that choice. You can also document your wishes in writing or through a living will.

Does DD mean anything else on a driver's license?

In the vast majority of cases, DD means organ donor. A very small number of states use DD for Designated Driver programs, but this is rare. If you are unsure what DD means on your specific license, contact your state's DMV directly — they can tell you what the marking signifies in your state.
