Signature Required is a delivery and order fulfillment designation used by medical supply distributors to ensure secure receipt of healthcare products. This service confirmation is commonly applied to shipments of controlled or high-value medical and surgical supplies delivered to skilled nursing facilities, home care agencies, and DME providers. Requiring a recipient signature at the time of delivery helps maintain chain-of-custody documentation, reduces the risk of lost or misdelivered packages, and supports compliance with healthcare procurement protocols. This designation is an essential component of reliable supply chain management in post-acute and long-term care distribution environments.
