How to Locate a UPIN Number

Until 2007, Medicare identified every physician in the United States who would bill to Medicare with the the Unique Physician Identification Number. The National Provider Identifier number eplaced UPIN in 2007. However, physicians, doctors, and others can look up UPINs using tools that are still available, including both online and paper resources.
