No, your blood type is not on your driver’s license in the United States. The federal REAL ID Act sets the minimum information every state-issued license must display, and blood type is not on that list. A small number of states now let residents add it voluntarily, but even then, any hospital will retest your blood before a transfusion.
What a Standard License Shows
Federal law requires every REAL ID-compliant license to display your full legal name, date of birth, gender, photograph, signature, address, a unique license number, and physical security features, along with a machine-readable barcode on the back.1Department of Homeland Security. REAL ID Act – Title II States can add their own fields on top of that, and most do: organ donor status, veteran designation, emergency contact registration, and endorsements or restrictions tied to your driving privileges. Blood type is not part of the default set in any state.
Why Blood Type Isn’t Standard
Three practical problems keep blood type off the card.
Emergency rooms do not rely on patient-reported blood type. Before any transfusion, lab technicians draw a fresh sample, run their own ABO and Rh typing, and cross-match against the donor unit. The wrong type can trigger a fatal hemolytic reaction, so the independent check happens every time regardless of what your wallet says.
Motor vehicle agencies also have no way to verify the information. Blood type requires a laboratory test, and DMV offices are not medical facilities. Self-reported blood type with no verification is arguably worse than none at all, because it creates a false sense of reliability.
Finally, blood type is health information. Printing it on a document you hand to bartenders, hotel clerks, and traffic officers raises real privacy concerns, even though HIPAA itself covers healthcare providers and insurers rather than the DMV.
States That Let You Add Blood Type Voluntarily
A handful of states have passed laws letting residents opt in to adding blood type to a driver’s license or state ID. As of 2026, at least four states offer or are implementing this option. Georgia was first, in 2014. Virginia followed in 2023, placing an optional blood type symbol near the organ donor indicator. Washington and Arkansas both have laws taking effect in 2026 that let residents add the information when they apply or renew.
In every case, the designation is optional and self-reported. Opting in does not change what happens at the hospital. Treat the label as a personal preference or a note for first responders rather than a medically actionable data point.
How to Find Out Your Blood Type
If you don’t already know your type, a few routes get you an answer.
- Check your medical records. If you’ve ever had bloodwork, surgery, or a pregnancy, your blood type is almost certainly documented. HIPAA gives you the right to request copies of your health records, including lab results, from any covered provider or health plan.2U.S. Department of Health and Human Services. Individuals’ Right under HIPAA to Access their Health Information 45 CFR 164.524
- Donate blood. The American Red Cross tests every unit it collects and can tell you your type at your appointment.3American Red Cross. What is Your Blood Type
- Use an at-home kit. Over-the-counter blood typing kits are sold at pharmacies and online, using a finger-prick sample and reagent cards. Accuracy varies, so treat the result as informational rather than clinical-grade.
Better Ways to Share Medical Info in an Emergency
If the real worry is making sure first responders know your blood type, allergies, or conditions when you can’t speak for yourself, a few tools work much better than a line on an ID.
Your phone is the most accessible option. Apple’s Medical ID, built into the Health app on every iPhone, stores your blood type, allergies, medications, conditions, and emergency contacts, and makes them accessible from the lock screen without a passcode.4Apple. Set up your Medical ID in the Health app on your iPhone Android devices offer a similar feature through their Safety or emergency information settings.
Medical alert jewelry still works well for chronic conditions. A bracelet or necklace engraved with your blood type, drug allergies, or a diagnosis like diabetes or epilepsy is visible the moment an EMT reaches you. It never runs out of battery.
A simple wallet card does the job too. A printed or handwritten card with your blood type, medications, allergies, emergency contacts, and physician information sits right next to the license first responders are already pulling out. It’s free, low-tech, and stays current as long as you update it.
Any of these gives emergency personnel faster, more detailed, and more reliable information than a single field on a government-issued ID could.
