A Type 2 NPI is the number assigned to an organization, facility or practice. Examples of health care providers that are issued Type 2 NPIs are hospitals, independent laboratories, ambulatory surgery centers, multiple physician practices or incorporated solo practices. A Type 1 NPI is issued to practitioners. When the practitioner represents his/her own unincorporated solo practice, the practice will not be issued a Type 2 NPI; the practitioner will be issued a Type 1 NPI only. If you represent an unincorporated solo practice and have received only a Type 1 NPI, please do not submit that NPI as a Type 2 Organizational NPI. Instead, submit the NPI as the practitioner’s NPI.
