Every person who signs up to be an organ donor offers hope — and, ultimately, a gift of life — to others in need.

And the need is great: Nearly 120,000 people in the United States are waiting for an organ transplant, according to the Organ Procurement and Transplantation Network.  

"These transplants are life-saving and life-enhancing," says Randall S. Sung, M.D., an associate professor of surgery at the University of Michigan Medical School. "It's easier than ever to be a donor."

Registration is simple and free. It can be completed online or when you obtain or renew a driver's license.

In honor of National Donate Life Month in April, consider the importance of the gesture with these facts and figures.
