National Kidney Services (NKS) is a non-profit organization that operates a donation collection service to support the National Kidney Foundation (NKF). Founded as a fundraising initiative, NKS collects clothing, household items, and other donated goods through scheduled residential pickups and drop-off locations across various regions in the United States. The organization uses a distinctive pickup model where residents can schedule free collections of their donated items through their website nkfpickup.com or via phone. These donated items are then sold through various retail partnerships, with proceeds supporting the National Kidney Foundation’s programs, including kidney disease research, patient education, and public health initiatives. NKS operates primarily in select metropolitan areas, maintaining a fleet of trucks for donation pickup services. The organization employs a system of scheduled neighborhood routes to maximize efficiency and environmental sustainability in their collection efforts. They accept a wide range of items including clothing, shoes, accessories, small appliances, and household goods, though specific acceptable items may vary by location. The organization maintains strict quality control standards for donated items and provides tax receipts to donors. Through its operations, National Kidney Services has become an important funding source for the National Kidney Foundation’s mission to prevent kidney and urinary tract diseases.
