National Provider Identifier

All HIPAA-covered health care professionals or suppliers need an NPI.

The NPI identifies you in HIPAA standard transactions with health plans, health care clearinghouses, and health care professionals.

You can apply for an NPI from NPPES in 1 of 3 ways.

1. Visit the NPPES webpage to use a web-based application process.
2. Complete, sign, and mail a paper application form (CMS-10114) to the NPI Enumerator. Get a hardcopy application through the NPI Enumerator by calling 1-800-465-3203 or TTY 1- 800-692-2326. Email requests to customerservice@npienumerator.com.
3. Allow an Electronic File Interchange Organization (EFIO) to send the application data on your behalf through a bulk enumeration process. For more information, visit the How to Apply webpage.
