how to get an npi number

To get an NPI number in the U.S., you apply through the federal NPPES system run by CMS, either online (fastest) or by mailing a paper form.

What an NPI Is (Quick context)

  • A National Provider Identifier (NPI) is a unique 10‑digit identification number for healthcare providers and organizations in the U.S.
  • It is required for many administrative and billing transactions under HIPAA, including Medicare and most insurance claims.

Step‑by‑step: How to get an NPI number

1. Decide if you need an NPI (and type 1 vs. type 2)

  • Type 1 NPI : For individual providers (physicians, residents, NPs, therapists, etc.).
  • Type 2 NPI : For organizations (clinics, group practices, hospitals, LLCs, corporations).
  • Many clinicians have both: one as a person (Type 1) and one for their incorporated practice (Type 2).

2. Gather required information

Before starting the application, you typically need:

  • Legal name (individual or organization).
  • Date of birth (for individuals).
  • Social Security Number or ITIN (or EIN for organizations).
  • Business/organization name and EIN, if applicable.
  • Mailing address and practice location address.
  • Contact information (phone, email).
  • Professional license information (if already licensed).
  • Other provider IDs you may have (Medicare/Medicaid numbers, etc.) (optional).
  • Provider taxonomy code (describes your specialty or status).

For residents and trainees, you usually select a taxonomy code like “Student, Health Care” until fully licensed.

3. Apply online through NPPES (recommended)

The fastest and most common way is online via the National Plan and Provider Enumeration System (NPPES).

Basic flow:

  1. Go to the official NPPES website (run by CMS).
  1. Create a user account (if you don’t already have one).
  1. Log in and start a new NPI application.
  1. Choose entity type (individual vs. organization).
  1. Enter all requested information (demographics, addresses, taxonomy, licenses, identifiers).
  1. Review carefully and submit electronically.

Key points:

  • The online form usually takes about 20–30 minutes if you have your documents ready.
  • Applying is free; there is no government fee to obtain an NPI.

4. Apply by mail (if needed)

If you cannot or prefer not to apply online, you can use a paper application.

  • Download and print the official NPI Application/Update Form.
  • Fill it out completely, sign it, and mail it to the address listed on the form (commonly the NPI Enumerator in Windsor Mill, MD).
  • Providers without a Social Security Number are often directed to use the paper form rather than the online system.

Paper applications take longer to process than online submissions.

5. How long it takes and how you receive your NPI

  • Properly completed online applications are often processed in about 10 days, sometimes sooner depending on volume.
  • Paper applications may take around 20 business days or more because of mail and manual processing.

After approval:

  • You receive your NPI via email from the official NPI Enumerator address, and you may also see it in your NPPES account.
  • Make sure to check spam/junk and add the sender to your safe list.

6. After you get your NPI

Once you have your NPI:

  • Share it with your employer, credentialing office, or residency program as requested.
  • Use it on claims, enrollment forms, and other healthcare transactions where an NPI is required.
  • Keep your NPPES login safe so you can update addresses, taxonomy, or other details if your status changes.

Mini FAQ and quick tips

  • Is there any cost?
    No, obtaining an NPI from CMS is free; if someone tries to charge you a “government NPI fee,” treat it as a red flag.
  • Do I need an NPI as a resident or student?
    Many training programs expect residents to get an NPI before starting or early in training, and you use a student/trainee taxonomy code until fully licensed.
  • Can someone apply for me?
    Large organizations sometimes use an Electronic File Interchange Organization (EFIO) to submit applications in bulk with your permission.
