The national UNOS membership is divided into 11 geographic regions. This regional structure was developed to:
- facilitate organ allocation
- provide individuals with the opportunity to identify concerns regarding organ procurement, allocation and transplantation that are unique to their particular geographic area
Each region holds at least two meetings per year and presents informational forums for transplant professionals and patients. The members in each region elect a regional councilor and an associate regional councilor, and each region is assigned a UNOS staff administrator to assist in coordinating regional activities with the regional councilors. Additionally, each region is represented on the Board of Directors and on each of the standing committees.
