Each part of the country is served by one OPO, the nonprofit that coordinates deceased organ donation in its area. Here is every one: who they are, where they are, how to reach them, and which transplant programs they work with, from the federal government’s own records.
Select a state on the map to list the OPOs that serve it, with phone numbers.
Addresses, phone numbers, and affiliated transplant programs come from the Health Resources and Services Administration’s data downloads (OPO and transplant center facts file), retrieved September 28, 2026. Current public names, states served, and CMS performance tiers (2023 data cycle) were compiled from opodata.org and CMS’s QCOR system by the open-source opo-scraper project. Where an OPO now uses a different public name than its registered name, both are shown.
CMS tiers come from the 2020 OPO Conditions for Coverage rule, which ranks OPOs on donation and transplantation rates: Tier 1 meets the top standard, and Tier 3 OPOs are at risk of decertification. Tiers are recalculated as new data is released. OPOs may serve only part of a listed state.
