Organ Donation: How It Works and How to Register Your Decision

June 10, 2026·5 min read·FinalKeepSake

More than 100,000 people are on the organ transplant waiting list in the United States at any given time. Each day, approximately 17 people die waiting. A single donor can save up to 8 lives. Registering your decision and communicating it to your family is one of the highest-impact things you can do as part of end-of-life planning.

How Organ Donation Works

Organ donation after death occurs in two main ways:

Donation after brain death

Brain death is the irreversible cessation of all brain function, including the brain stem. It is legally and medically equivalent to death. A person who is brain dead can be maintained on mechanical ventilation and other support to keep organs viable for transplant. Donation after brain death allows for the widest range of organ and tissue donation.

Donation after cardiac death (DCD)

In DCD, donation occurs after the heart has stopped beating following the withdrawal of life-sustaining treatment for a patient who is not brain dead but has no prospect of recovery. Kidneys, liver, and lungs can often be recovered in DCD circumstances.

What Can Be Donated

Organs: Heart, both lungs, liver, both kidneys, pancreas, intestines — up to 8 lives saved by a single donor.

Tissues: Corneas (restoring sight), heart valves, bone, skin (for burn treatment), tendons, blood vessels, cartilage.

Most people can be donors regardless of age or medical history — the procurement organization evaluates each case individually. Don't self-disqualify based on assumptions about your health.

How to Register

Registering is simple and takes minutes:

  • State registry via DMV: Check the organ donor box when getting or renewing your driver's license or state ID. This is the most common registration method and is legally binding in all 50 states.
  • RegisterMe.org: The national registration platform that connects directly to all 50 state registries. Takes about 2 minutes.
  • DonateLife.net: Operated by Donate Life America, also links to state registries.

Your registry registration is legally sufficient authorization in all 50 states — families cannot legally override a registered decision. That said, families are always consulted in practice, and communicating your wishes to your family is essential to ensuring they're honored.

Communicating Your Wishes

Registration is not enough on its own. The most important thing you can do alongside registering: tell your family and next of kin about your decision. In the emotionally devastating moments immediately following a death, your family will be asked about donation. If they know your wishes in advance, they can honor them with confidence. If they don't, doubt and conflict can lead to donations not happening even when the deceased was registered.

Talk to your family, write your wishes in your advance directive and letter of instruction, and make your decision clear to the person most likely to be present at your death.

Addressing Common Concerns

"Doctors won't try as hard to save me."

False. The medical team treating you is completely separate from any organ procurement process. Your donor status is unknown to them and irrelevant to your care. This separation is both ethical and legally required.

"My religion prohibits organ donation."

Most major world religions either support or take no official position against organ donation, viewing it as an act of giving life. A small number of religious communities have specific concerns; if this is a consideration for you, consult your religious leader for the specific position of your faith tradition.

"I'm too old or unhealthy to donate."

There is no age cutoff for organ donation. Donors in their 80s and 90s have successfully donated. Medical suitability is evaluated individually at the time of death by the organ procurement organization. Don't assume you can't donate.

"My family will be charged."

Donation costs are not billed to the donor's family. The organ procurement organization covers all costs related to procurement.

Living Donation

Living donation — donating a kidney, a portion of liver, or bone marrow while alive — is a separate decision. Living donors can give a kidney (people can live healthy lives with one kidney) or a portion of their liver (which regenerates). Living donation is considered independently of end-of-life decisions; contact a transplant center directly for information.

Frequently Asked Questions

Does being an organ donor affect the medical care you receive?
No. This is the most common concern and the most important myth to address: your organ donor status has absolutely no effect on the medical care you receive while alive. The medical team treating you has no knowledge of your donor status and no involvement in any organ procurement process. Organ donation only becomes relevant after all life-saving efforts have been exhausted and brain death (or, in some cases, cardiac death) has been declared — by a completely separate team from the one that provided your care. The legal separation between the treating medical team and the organ procurement team is absolute.
What organs and tissues can be donated after death?
A single donor can potentially save up to 8 lives through organ donation and enhance dozens more through tissue donation. Organs that can be donated: heart, lungs (both), liver, kidneys (both), pancreas, and intestines. Tissues that can be donated: corneas (restoring sight), heart valves, bone, skin (for burn treatment), tendons, and blood vessels. Bone marrow donation (for living or deceased donors) is a separate process. Not all organs and tissues are viable in every donor — viability depends on age, health, cause of death, and the time between death and procurement. Specific medical conditions may disqualify specific organs or tissues but rarely disqualify donation entirely; the organ procurement organization evaluates each case individually.
How do you register as an organ donor in the United States?
The easiest method: register through your state's DMV (driver's license or ID issuance/renewal — the "organ donor" checkbox on the license form registers you on the state registry). Additionally, register at RegisterMe.org (the national platform that connects to all 50 state registries) or DonateLife.net. Important: registering with your state registry is legally sufficient authorization in all 50 states — your family cannot override a registered decision, though in practice family members are always consulted and communication is important. Also add your donor preference to your advance directive and ensure your family knows your wishes, because in emergency situations families are often the practical decision-makers.
