CMS recommends that physicians know and maintain their National Plan and Provider Enumerator System User IDs and passwords, reset their NPPES passwords at least once a year and review their records to ensure that the information is current. To view or update your information, visit https://nppes.cms.hhs.gov/NPPES/Welcome.do and follow the NPI hyperlink, or access the NPI Registry to view Freedom of Information Act (FOIA)-disclosable NPPES data. The required information cannot be deleted; however, it can be updated. Certain information is inaccessible via the web, thus requiring changes to be made via the paper NPI Application/Update Form.  You can also call the NPI enumerator to request a paper application at 1-800-465-3203.
