DD stands for "Designated Driver" on some licenses, but it usually means something else

The letters DD on your driver's license most commonly stand for Donor Designation — it marks you as someone who has agreed to donate organs, tissues, or eyes after death. Some states print it directly on the front or back of the card; others use a symbol or note in a different location. A few states use DD to mean Designated Driver on a special license class, but that is much less common.

The meaning depends on your state. If you see DD on your license and are unsure which it refers to, your state's Department of Motor Vehicles website will clarify. You can also check your license renewal paperwork — most states ask about organ donation during the process process and show your choice on the card itself.

Key Takeaways

  • DD most often means Donor Designation, showing you have registered as an organ and tissue donor.
  • Some states print DD on the license itself; others use a symbol, a note in the margin, or a separate registry card.
  • A few states use DD to indicate a Designated Driver license class, which has different rules than a standard license.
  • You can change your donor status at any time by contacting your state's DMV or organ donation registry.

How organ donor designation works on your license

When you renew or first obtain a driver's license, your state's DMV asks whether you want to register as an organ donor. If you say yes, the state adds a mark to your license — usually DD, a heart symbol, or the word "Donor." This mark tells hospital staff and emergency responders that you have made a donation decision, so they know to contact your family or check the state's donor registry.

The mark on your license is not a legal document by itself. It is a signal. When death occurs, hospital staff will look up your name in your state's organ donation registry to confirm your wishes and find any instructions you left. Some states also allow you to register through a national database called the Donate Life Registry, which hospitals can access across state lines.

Registering as a donor does not cost anything and does not affect your insurance or medical care while you are alive. Hospitals will not withhold treatment based on your donor status.

What happens if you change your mind about donation

Your donor status is not permanent. You can remove yourself from the registry or change your decision at any time by contacting your state's DMV, your state's organ procurement organization, or the Donate Life Registry if you registered there. When you renew your license, you can also tell the DMV to remove the DD mark.

If you want to change your status before your next renewal, call your state's DMV directly and ask how to update your donor registration. Some states allow you to change it online through their DMV portal; others require a phone call or a visit in person. The process usually takes a few days to a few weeks to show up in the registry, so if you are having surgery soon, call ahead to make sure the change is recorded.

DD as a Designated Driver license class (less common)

In a small number of states, DD refers to a Designated Driver license class or endorsement. This is not a separate license you explore for — it is a notation on a standard license that shows you have completed a designated driver training program or meet certain requirements.

States that use this system typically offer it as part of a drunk driving prevention program, often in high schools or community colleges. The DD mark signals that the driver has taken a course on the risks of impaired driving and has committed to driving sober. Requirements and what the mark means vary by state, so check your state's DMV website if you think this applies to you.

How to read other marks and codes on your license

Driver's licenses carry several other codes and marks beyond DD. Common ones include restriction codes (like "B" for corrective lenses or "E" for automatic transmission only), endorsement codes (like "H" for hazmat or "P" for passenger vehicles), and class codes (like "D" for regular passenger vehicle or "A" for motorcycle). Each state uses its own system, so a code that means one thing in one state may mean something different in another.

If you see a code on your license and do not know what it means, your state's DMV website has a legend that explains all of them. You can also call your local DMV office — staff there can tell you what any mark on your license means and whether it affects your driving privileges.

Checking and updating your donor status

To find out whether you are currently registered as a donor, visit your state's organ donation registry website or call your state's DMV. You can also check the Donate Life Registry at donatelife.net, which covers most states and allows you to search your registration status and update it if needed.

If you want to register as a donor and your state's DMV did not ask you during your last license renewal, you can register separately through your state's organ procurement organization or the Donate Life Registry. Registration is free and takes a few minutes. You will receive confirmation, and your name will be added to the registry so hospitals can find your wishes if needed.

Frequently Asked Questions

Does having DD on my license mean hospitals will take my organs without asking my family?

No. Hospitals will contact your family first and explain your wishes. Your family has the right to ask questions and decline donation even if you are registered. The DD mark straightforward tells staff that you have made a decision, so they know to check your registration and talk to your family about it.

Can I register as a donor if I do not have a driver's license?

Yes. You can register through your state's organ donation registry or the Donate Life Registry without a license. Some states also allow you to register at the DMV when you get an ID card instead of a license. Call your state's DMV or visit the Donate Life website to find the registration method that works for you.

What if my license shows DD but I do not remember registering?

You may have registered during a license renewal without remembering, or someone else may have registered on your behalf (some states allow family members to register you). Contact your state's DMV or organ donation registry to confirm your status and change it if you wish. You can remove yourself from the registry at any time.

Does DD affect my ability to get a job or insurance?

No. Organ donor status is private medical information and does not appear on background checks or affect employment or insurance decisions. Employers and insurers cannot see your donor status unless you tell them.
