You update your NPI address through the NPPES system, the official registry run by CMS

Your National Provider Identifier (NPI) is a ten-digit number assigned to you by the Centers for Medicare & Medicaid Services (CMS). It stays with you throughout your career, but your address on file needs to stay current. You change it by logging into the NPPES (National Plan and Provider Enumeration System) portal, the same system where your NPI was originally created.

The process takes about 15 minutes if you have your login credentials ready. Changes typically show up in the public NPI registry within 24 hours, though some insurance companies and clearinghouses may take longer to sync the update to their own records.

Key Takeaways

  • You access the NPPES portal at nppes.cms.hhs.gov using your existing username and password, or you can create a new account if you have never logged in before.
  • The address you update in NPPES is your practice location or mailing address, depending on your provider type and whether you have multiple locations.
  • After you submit the change, CMS processes it within one business day, but insurance companies and billing systems may take several days to receive the update.
  • If you manage multiple locations or have a group NPI in addition to an individual NPI, you will need to update each record separately.

Logging into NPPES and finding your record

Go to nppes.cms.hhs.gov and click "Log In" in the upper right corner. If you have logged in before, use your existing username and password. If this is your first time, click "Create an Account" and follow the prompts to set up your credentials using your NPI and date of birth.

Once logged in, you will land on your dashboard. Click "Update NPI" or "Manage Your NPI" (the exact wording varies slightly depending when your account was created). The system will display your current record with all the information CMS has on file: your name, credentials, practice address, phone number, and tax ID.

Changing your mailing address versus your practice location

NPPES distinguishes between your practice location address (where you see patients or deliver services) and your mailing address (where you receive mail). Most providers update the practice location address. If you moved your office, update the practice location. If you kept your office but changed where you want mail sent, update the mailing address instead.

For individual providers (NPI type 1), you typically have one practice location on file. For group practices or organizations (NPI type 2), you may have a main office address plus secondary locations. Check which address field applies to your situation before you make changes.

Entering the new address and submitting

Click into the address field you need to change. Clear the old address completely and type the new one. Use standard U.S. Postal Service formatting: street address on the first line, city, state, and ZIP code on the second. Do not use abbreviations like "St." or "Ave." unless USPS requires them for your specific address.

After you enter the new address, scroll down and click "Submit" or "Save Changes." The system will ask you to confirm the address is correct. Review it once more, then click the final confirmation button. You will see a message confirming the submission was received, usually with a timestamp.

What happens after you submit and how long it takes

CMS processes address changes within one business day. The updated information appears in the public NPI registry (accessible at npiregistry.cms.hhs.gov) within 24 hours of submission. However, insurance companies, pharmacy benefit managers, and billing clearinghouses maintain their own copies of your NPI record and update on their own schedules — sometimes within days, sometimes within weeks.

If you are changing your address because you moved your practice, notify your major payers directly as well. Do not assume they will pull the update from the public registry automatically. Send them a letter or use their provider relations portal to report the change, and ask for written confirmation they have updated their records.

Updating multiple NPIs and group records

If you have both an individual NPI and a group NPI, you must update each one separately in NPPES. Log in, update the first NPI, submit, then log out and log back in (or switch records if the system allows it) to update the second. The same applies if you are listed as an authorized official for multiple organizations or group practices.

If you are a staff member updating an address on behalf of a provider or organization, you will need to be listed in NPPES as an authorized official with edit permissions. If you do not have access, contact the provider or the organization's compliance officer and ask them to grant you those permissions or make the change themselves.

Troubleshooting login and access problems

If you cannot remember your NPPES password, click "Forgot Password" on the login page. CMS will send a reset link to the email address on file. If you do not receive the email within 15 minutes, check your spam folder or try again.

If you have never created an NPPES account and the system says your NPI is not found, verify you are entering your ten-digit NPI correctly (no dashes or spaces). If the problem persists, call the NPPES help line at 1-800-465-3203. They can confirm your NPI exists and help you set up your account. Wait times are typically shortest on Tuesday through Thursday mornings.

Frequently Asked Questions

How long does it take for insurance companies to see my new address?

The public NPI registry updates within 24 hours, but individual insurance companies sync on their own schedule. Some update within 48 hours; others take one to two weeks. If the address change is urgent for billing or credentialing, contact your major payers directly and ask them to update their records manually rather than waiting for the automatic sync.

Can I change my NPI address if I have an outstanding compliance issue or audit?

Yes. Address changes are routine administrative updates and do not trigger any review or hold your record. However, if you are under investigation or audit, notify the investigating agency of your new address so they can reach you. Do not assume they will check NPPES automatically.

What if I have multiple practice locations?

NPPES allows one primary practice location per individual NPI. If you have multiple offices, you can list only one in your NPI record. Some providers create separate group NPIs for each location, or they list their main office and provide secondary locations to payers through other channels. Check with your billing department or payers about how they want multiple locations reported.

Do I need to update my address anywhere else besides NPPES?

NPPES is the official source, but you should also update your address with your state medical board, your DEA registration (if you prescribe), your malpractice insurance carrier, and any credentialing files you maintain with hospitals or surgery centers. These systems do not pull from NPPES automatically.

What if I closed my practice and no longer have a practice location?

You can enter a mailing address or your home address as your practice location if you no longer have an office. Some retired or inactive providers use a P.O. box. NPPES requires a valid address on file; you cannot leave the field blank. If your NPI is no longer in use, you can request deactivation through NPPES instead.
