United Network for Organ Sharing

Located in Richmond, Virginia, the United Network for Organ Sharing (UNOS) is a non-profit, scientific and educational organization* that administers the nation’s only Organ Procurement and Transplantation Network (OPTN), established by the U.S. Congress in 1984. Through the OPTN, we:

  • collect and manage data about every transplant event occurring in the United States
  • facilitate the organ matching and placement process using UNOS-developed data technology and the UNOS Organ Center
  • bring together medical professionals, transplant recipients and donor families to develop organ transplantation policy

UNOS was awarded the initial OPTN contract on September 30, 1986. UNOS is the only organization to ever manage the OPTN, and has continued to administer the contract for more than 22 years and five successive contract renewals. UNOS provides the OPTN with a functional, effective management system incorporating the Board of Directors, committees and regional membership to operate OPTN elements and activities.
