How many digits does an NPI number contain?

An NPI, or National Provider Identifier, consists of 10 digits. This unique identification number is assigned to healthcare providers in the United States to facilitate standardized identification in healthcare transactions. The format of an NPI is a 10-digit numeric value that is not based on any other identifiers.

Each NPI is unique, ensuring that the same provider cannot be identified by more than one number. This is important for maintaining accurate records and streamlining processes within healthcare systems. Understanding the structure and significance of the NPI is crucial for healthcare professionals involved in billing and patient care.
