How to get an NPI number: apply through NPPES, the free federal system CMS uses to assign provider IDs. You create an Identity & Access account, fill out one online application, and receive your 10-digit National Provider Identifier in about ten business days. There is no fee, and the number stays with you for life.
Key Points About Getting an NPI
- Free and permanent. There is no application fee, no renewal, and no annual cost. Your NPI follows you for your whole career, through job changes, moves, and new specialties.
- 10 digits, one per person. An NPI is a 10-digit number. As an individual you get exactly one (a Type 1), no matter how many states you end up practicing in.
- Two types. A Type 1 NPI identifies an individual clinician. A Type 2 identifies an organization, like a group practice or clinic. Some incorporated solo providers need both.
- About 10 business days online. A complete online application is usually enumerated in roughly 10 business days. The paper form (CMS-10114) runs closer to 20.
- Required since 2007. The NPI has been the national standard provider identifier under HIPAA since May 23, 2007. If you bill electronically or work with a HIPAA-covered entity, you need one.
- An NPI is not a license. Holding an NPI does not prove you are licensed or credentialed. Those are separate checks, and payers verify them on their own.
For an individual clinician, getting an NPI is one of the few genuinely easy steps in the whole credentialing process. It is free, it takes about 10 minutes of typing, and most clean applications come back inside two weeks. In our experience helping providers across all 50 states, the delays almost never come from CMS. They come from a name that does not match the license, a missing taxonomy code, or a provider who already had an NPI from residency and forgot. Apply early, save your login, and treat the NPI as the first domino, not the finish line.
What Is an NPI Number, and Who Needs One?
An NPI, or National Provider Identifier, is a unique 10-digit number that CMS assigns to U.S. health care providers through NPPES, the National Plan and Provider Enumeration System. It carries no hidden meaning. It doesn’t encode your state, specialty, or license number, and it never expires.
The number exists because of HIPAA. The law required one standard ID for every provider who sends health information electronically, so claims, referrals, and eligibility checks all point to the same identifier no matter which system processes them. Before 2007, every payer used its own provider numbers, and the mismatch was a mess.
So who actually needs one? The short answer: almost anyone who treats patients and touches the billing or electronic-transaction side of care. That includes physicians, nurse practitioners, physician assistants, registered nurses who bill, dentists, pharmacists, physical and occupational therapists, speech-language pathologists, and many more. If you are a HIPAA-covered provider, or you plan to bill Medicare, Medicaid, or commercial insurance, you need an NPI.
Real scenario: A family nurse practitioner finishing school in Phoenix lines up her first job before her license posts. She applies for her NPI as a student, gets the number in under two weeks, and updates the record with her license details the day the board issues them. By the time her employer starts payer enrollment, the NPI is already sitting there, ready to use.
Type 1 vs. Type 2 NPI: Which Do You Need?
A Type 1 NPI identifies you as an individual person. A Type 2 NPI identifies an organization, such as a group practice, clinic, hospital, or pharmacy. Most clinicians applying for the first time need only a Type 1. The two types answer a simple question: is the number for a human, or for a business?
Think of it this way. Your Type 1 is like your personal passport. It is tied to you, and you carry it everywhere you practice. A Type 2 is more like a company’s tax registration: it belongs to the entity, not to any one person, and a business can hold several if it runs separate subparts or locations.
| Feature | Type 1 (Individual) | Type 2 (Organization) |
|---|---|---|
| Who it identifies | A single clinician (you) | A business: group practice, clinic, hospital, lab |
| Examples | Physician, NP, PA, RN, therapist, dentist | LLC, professional corporation, hospital, pharmacy |
| How many you can hold | Exactly one, for life | As many as the structure needs (one per subpart) |
| When you need it | You treat patients and bill or transmit HIPAA transactions | You bill under a business name, not your own |
| Sole proprietor note | Needs only a Type 1, even with an EIN | An incorporated practice may need both a Type 1 and a Type 2 |
If you are a salaried physician or a new nurse joining a hospital, you almost certainly need just a Type 1. The hospital already has its own Type 2. The decision only gets interesting when you own a practice or set up a professional corporation, and even then the rule is clean: the person gets a Type 1, the company gets a Type 2.
What to Gather Before You Get an NPI Number
Before you start the application, pull together a handful of details. The online form is short, but it stalls the moment you are missing a taxonomy code or an exact license number. Five minutes of prep saves you from re-opening the application three times.
Checklist: what to have ready before you apply
- Your Social Security Number or ITIN (entered only in the secured field the form provides)
- Your state license number and the issuing state, if you are already licensed
- Your primary taxonomy code, picked from the NUCC code set
- A practice or mailing address and a business phone number
- An email address you check often, since CMS sends your NPI there
The taxonomy code trips people up more than anything else on this list. It is a 10-character code that describes your provider type and specialty, and you select it yourself. CMS points applicants to the National Uniform Claim Committee (NUCC) code set, where you can search by provider type, classification, and specialization. You may list more than one, but you have to mark a single code as your primary. Pick the one that matches the work you will actually bill for.
Pro tip: Set up your Identity & Access (I&A) account first, before you touch the NPI form. NPPES will not let you apply without one, and the account is also what you will use years from now to update your address or add a practice location. Store the username and password somewhere you can find them. Locked-out providers email customer service and wait, and that wait is entirely avoidable.
How to Get an NPI Number Online, Step by Step
The fastest way to get an NPI number is the web application. Log in to NPPES, complete the five sections, and submit. A clean online application is the single biggest factor in a quick turnaround, faster than the paper route by roughly half. Here is the whole flow.
- Create an Identity & Access (I&A) account. On the NPPES home page, choose “Create or Manage an Account.” You will be redirected to the I&A system to register. This login is yours to keep.
- Log in to NPPES. Return to NPPES with your I&A user ID and password. This is where you create and later maintain every NPI record tied to you.
- Pick Type 1 or Type 2. An individual clinician selects Type 1. If you are enumerating a business entity, select Type 2 and have the authorized official ready to sign off.
- Fill in your details and taxonomy code. Enter your name exactly as it appears on your license, your address, contact info, license number, and your primary taxonomy code. Double-check the name field.
- Review, certify, and submit. Confirm everything, certify the application, and submit. CMS emails the 10-digit NPI to the address on file once the record is enumerated.
Two other routes exist if the web form does not fit. You can mail the paper CMS-10114 form to the NPI Enumerator in Windsor Mill, Maryland, and staff there key it in for you. Or, for high-volume situations, an Electronic File Interchange organization (EFIO) can submit applications in bulk on behalf of many providers at once. For one clinician, the online form wins every time.
Watch out: Use the same name on your NPI that appears on your state license and your other legal documents. A nickname here, a maiden name there, and your records stop matching across payer systems. CMS also warns that issuing an NPI does not confirm you are licensed or credentialed, so a number in hand is not permission to bill on its own.
How Long Does It Take to Get an NPI Number?
A properly completed online application can produce an NPI in about 10 business days, and sometimes faster. The paper form takes roughly 20 business days because a person has to key it into NPPES first. Timing depends on application volume, whether you applied online or by mail, and whether the file was complete.
Cost is the easy part: there is none. Applying for an NPI is free, there is no annual fee to keep it, and there is nothing to renew. CMS issues and maintains the number at no charge. Anyone offering to “register your NPI” for a fee is charging you for something you can do yourself in one sitting.
By the numbers: $0 to apply or maintain. 10 digits in every NPI. One Type 1 number per person, for life. About 10 business days for a complete online application. The standard has been in place since May 23, 2007.
After Approval: Finding, Updating, and Protecting Your NPI
Once your NPI is issued, it goes into a public file. Anyone can look up your number, your listed specialty, and your practice address through the NPI Registry, the public search tool CMS runs on top of NPPES. That visibility is by design, and it is why keeping your record current matters.
If you ever misplace your number, you don’t reapply. You can look up an existing NPI in the public registry in seconds using your name and state. When your details change, log back in to NPPES and edit the same record. Moving to a new state doesn’t mean a new NPI. The number is portable for life, so you simply add the new practice address and keep your state licenses current separately.
Your NPI is portable for life. Your state license is not. Keep them on separate mental tracks, because payers check both.
It also helps to know what an NPI is not. It’s not your DEA registration, which is a separate federal number for prescribing controlled substances and runs on its own three-year clock. It isn’t your Tax ID or EIN, which identifies a business for tax purposes. And it doesn’t enroll you with insurers. After you have the number, you still have to enroll with each insurance payer and complete credentialing, with your NPI attached to those applications.
Common Reasons an NPI Application Stalls
When an NPI takes longer than it should, the cause is usually small and fixable. From the files we process, the same handful of issues come up again and again, and none of them are CMS being slow.
- Name mismatches. The name on the application does not match the license or legal ID, so downstream payer systems reject it later.
- Missing or wrong taxonomy code. The applicant guesses, picks a code that does not fit, or forgets to flag a primary.
- A duplicate NPI. Residents and students often already have a number and do not realize it. Applying again creates a tangle that has to be cleaned up.
- Incomplete contact details. A bounced email or an old address means the NPI is issued but the provider never sees it.
We see new grads skip the NPI entirely until a payer asks for it, then scramble during onboarding. If you’re early in your career, the better move is to apply now, while you’ve got ten quiet minutes, rather than under a start-date deadline. When you are juggling several state licenses or a brand-new practice entity at the same time, it can be worth deciding whether to handle the paperwork yourself or bring in help so nothing falls between the cracks.
Frequently Asked Questions
Do nurses, PAs, and therapists need an NPI number?
Yes. The NPI is not just for physicians. Nurse practitioners, registered nurses who bill, physician assistants, physical and occupational therapists, speech-language pathologists, dentists, and pharmacists all need a Type 1 NPI if they take part in HIPAA-covered electronic transactions or bill insurance.
How do I find my NPI number?
You don’t need to reapply if you lost it. Just search the NPI registry with your name and state, and your 10-digit number comes up along with your listed specialty and practice address. The registry is public and free to use.
Is there a fee to get an NPI number?
No. Applying for an NPI is completely free, there is no annual maintenance fee, and the number never needs renewing. CMS issues and maintains it at no cost to the provider. Be wary of any third party that charges just to submit the form.
How is an NPI different from a DEA number or a Tax ID?
Each serves a different job. Your NPI identifies you as a health care provider in standard transactions. A DEA registration authorizes you to prescribe controlled substances. A Tax ID or EIN identifies a business for tax purposes. Many providers need all three, and they are issued by different systems.
Can I get an NPI before I am licensed?
Yes. Students and pre-licensed professionals can obtain an NPI and then update the record with their license details once the state board issues a license. Applying early is common for residents and new grads, and it removes one task from a busy onboarding window.
Can one person have more than one NPI?
As an individual, no. You hold a single Type 1 NPI for your entire career. The only time a person ends up with two numbers is when they also run a separate legal business entity, which gets its own Type 2 NPI. A single record can carry several taxonomy codes, so a multi-specialty clinician still needs only one Type 1.
This article provides general guidance only. NPI and credentialing requirements can change, and individual situations differ. Always verify current steps with the official NPPES system at nppes.cms.hhs.gov before you apply or update your record. Last fact-checked: June 23, 2026.
