For people who live in the United States. Live somewhere else? Find your country.

Three registries sign up people who live in the United States. You only need to join one. NMDP says anyone who registered with another U.S. organization is already on the registry it manages, so people in the United States need to register only once. 8 Checked .

Bone marrow registries are also called stem cell registries.

Which registry should I join in the United States?

NMDP18 to 35
DKMS18 to 55
Gift of Life18 to 35

In the United States, NMDP signs people up directly from 18 to 35, while DKMS, an NMDP member organization, signs up people from 18 to 55 into the same registry. Gift of Life, an affiliated registry of NMDP, is also among the U.S. donor centers NMDP lists. 1 8 10 12 14

In the United States, the donor registry belongs to the federal C.W. Bill Young Cell Transplantation Program, which Congress created through the Stem Cell Act of December 2005 and renewed in 2010, 2015 and 2021. HRSA says NMDP operates the registry under federal contracts. 20 21

HRSA says the U.S. registry began in 1987 as the National Bone Marrow Donor Registry, started with a grant through the U.S. Department of the Navy. NMDP, known over the years by other names including the National Marrow Donor Program, took the single name NMDP in early 2024 and runs the same registry. 4 20

NMDP lists four U.S. donor centers: NMDP in Minneapolis, DKMS in New York, Gift of Life Marrow Registry in Boca Raton, Florida, and the C.W. Bill Young DoD Marrow Donor Program in Rockville, Maryland. NMDP says where you donate depends on the organization you signed up through. 8

Salute to Life, the Department of Defense program, signs up service members and their dependents, reservists, National Guard and Coast Guard members and DoD civilians aged 18 to 60, at walk-in sites on bases or with a mailed kit. Salute to Life says it has recruited more than 1 million potential donors since 1991. 7 16

Gift of Life, based in Boca Raton, Florida, began with the donor drives held for its founder, Jay Feinberg, whose four-year search for a matching donor ended in May 1995. Gift of Life says that in 2001 it became the first registry to use bloodless testing, the cheek swab, at donor drives. 17

Gift of Life says it introduced Hero Gum in 2025, a gum new donors chew so that it can collect the tissue type information used for matching, its first new collection method since it introduced cheek swabs in 2001. 17

Every U.S. donor center feeds the registry NMDP manages, so one sign-up is enough. 8

NMDP lists 19 public cord blood banks in its network, among them Bloodworks in Seattle, the Carolinas Cord Blood Bank at Duke University and the M.D. Anderson Cord Blood Bank in Houston. On Oct 18, 2026, its list of hospitals that collect donated cord blood for these banks named 108 hospitals in 19 states. 6

HRSA tells expectant parents in the United States to talk with their doctor or midwife between the 28th and 34th week of pregnancy and to find out whether their hospital collects cord blood for public donation, because donation isn’t possible in every hospital. 23

The federal Stem Cell Acts require HHS to contract with qualified public cord blood banks for a National Cord Blood Inventory, which aims to collect at least 150,000 new cord blood units for transplants, HRSA says. 22

What happens after I join?

If an NMDP volunteer in the United States is asked to donate, NMDP says it pays for all donation and travel costs, including flights, hotels and meals for the donor and a companion. 1

If a U.S. service member who registered matches a patient, NMDP says Salute to Life helps with command authorization, no-cost TAD/TDY orders and travel arrangements from the duty location. 7

In the United States, federal employees can use up to 7 days of paid leave each calendar year to serve as a bone marrow donor, the U.S. Office of Personnel Management says, as a separate kind of leave in addition to annual and sick leave. 24

Gift of Life’s summary of state donor leave rules, updated in January 2024, says most states protect employees from losing their job for taking leave to donate bone marrow. In California, it says, employers with more than 15 employees must give up to five days of paid leave a year to donate. 31
