Where can I learn more about the NPI application process?
Up-to-date information regarding the NPI is available on the NPPES web site at https://nppes.cms.hhs.gov/NPPES. You may also contact the enumerator by telephone at 1-800-465-3203 or TTY 1-800-692-2326. In addition, an instructional web tool, called the NPI Viewlet, is now available for viewing at http://www.cms.hhs.gov/apps/npi/npiviewlet.asp.
