Go to nppes.cms.hhs.gov and click “Create Account.” You will need your name, email address, and to answer 5 security questions. This I&A account also gives you access to PECOS (Medicare enrollment) using the same credentials — create it once and use it for both.

• ↗ NPPES — Create Account & Apply
• Email from confirmation: customerservice@npienumerator.com — add to your safe sender list
• Save your I&A User ID and password — you will use it for PECOS enrollment too

After logging in, select “Add NPI” → “Individual.” You will complete 6 sections:

• Personal information: full legal name, SSN, date of birth, gender
• Contact information: mailing address, practice address, phone, fax, email
• Provider taxonomy: your NP specialty code (see table below) — this determines which insurance specialties you appear in
• License information: state license number, state, expiration date
• Other names: maiden name or other legal names if applicable
• Identifiers: any existing Medicare/Medicaid provider numbers (leave blank if new)

Application takes 20–30 minutes. Submit and receive your 10-digit NPI number typically within minutes to a few hours by email.

• ↗ NUCC Taxonomy Code Search
• ↗ NPI Registry — Look Up Any Provider

You must update NPPES within 30 days if any of the following changes: practice address, phone number, taxonomy code, license number or expiration, legal name. Log into nppes.cms.hhs.gov with your I&A credentials and select “Manage NPI.” PECOS and most payer systems pull directly from NPPES — outdated records cause claim rejections.

Log into nppes.cms.hhs.gov with your same I&A credentials. Select “Add NPI” → “Organization.” You will need: your EIN, legal business name exactly as registered with your state (must match Secretary of State records exactly), business address, and the authorized official’s information (you, as the sole member).

• Legal name must match your LLC/PLLC filing exactly — even small variations (LLC vs. L.L.C.) cause problems
• Use your physical practice address as the primary address
• Add your Type 1 NPI as the authorized official’s NPI
• Taxonomy for the organization is typically the same as your Type 1 (e.g., 363L00000X for FNP)

After receiving your Type 2 NPI (usually within minutes to 24 hours), verify both your Type 1 and Type 2 records in the public NPI registry. Search by NPI number and confirm: address, taxonomy code, license number, and organization name are all exactly correct. Payers and CAQH pull from this registry.

• ↗ NPI Registry — Verify Your Records
• Allow 24–48 hours for records to appear publicly after issuance
• Discrepancies between your NPI record and other enrollment applications are the #1 cause of processing delays
