Find a doctor's National Provider Identifier, or NPI, number using the NPI lookup tool available at NPIdb. Health care providers who are members of the National Plan & Provider Enumeration System, or NPPES, have a designated 10-digit NPI numeric code, states NPIdb.
Under the 1996 Health Insurance Portability and Accountability Act of the United States, a physician's NPI number is used in all medical transactions involving insurance policies, notes NPIdb. The process of locating a doctor's assigned NPI number takes a few steps to complete.
