How to Search for an NPI Number by Name?
Quick Answer
To search for an NPI number by name, go to the NPPES NPI Registry (npiregistry.cms.hhs.gov) or NPIxray (npixray.com) and enter the provider's first and last name. For best results, add the state to narrow the search — common names like 'Smith' or 'Johnson' may return thousands of results without geographic filtering. You can also filter by specialty (taxonomy), city, and ZIP code. The NPPES database contains over 8.2 million registered NPIs. NPIxray enhances name search results by showing each provider's Medicare billing summary alongside their directory information, making it easy to verify you have the right provider. Searches are free, instant, and require no registration on either platform. Source: NPIxray analysis of 1.175M Medicare providers and 8.15M billing records.
Step-by-Step Name Search
Using the NPPES NPI Registry: Navigate to npiregistry.cms.hhs.gov. Select the NPI type (Individual for Type 1, Organization for Type 2). Enter the provider's first name and last name. Add the state for best results. Optionally add city, ZIP code, or taxonomy. Click Search.
Using NPIxray: Go to npixray.com. Enter the provider's name in the search bar. Results will show matching providers with their NPI number, specialty, location, and a preview of their Medicare billing data. Click on any result to see the full revenue analysis.
Both tools return results instantly. The NPPES Registry shows basic directory information, while NPIxray adds Medicare billing intelligence to each result.
Tips for Accurate Name Searches
Use the provider's legal name, not their preferred name or nickname. A provider who goes by Bob may be registered as Robert. For providers with compound last names, try searching with and without the hyphen. International names may be registered in a different order than commonly used (family name vs. given name).
If the name search returns too many results, add filters: state narrows results dramatically, specialty/taxonomy eliminates providers in other fields, and city or ZIP code pinpoints the location. If the name search returns zero results, check the spelling, try alternative name formats, and verify that the provider has an NPI (not all providers have registered, particularly those who recently entered practice).
Searching for Organization NPIs
To find a group practice, hospital, or organization NPI, search by organization name rather than individual name. Select Type 2 (Organization) on the NPPES Registry to filter results. Organization names are registered as legal business names, which may differ from doing-business-as (DBA) names.
For example, a practice known as Downtown Family Medicine may be registered as Downtown Family Medicine LLC or John Smith MD PA. Try searching for partial names if the full legal name is unknown. The NPPES Registry supports partial name matching.
Verifying the Correct Provider
When a name search returns multiple results, verify the correct provider by checking: practice address (does it match the location you expect?), specialty/taxonomy (does it match their known specialty?), NPI enumeration date (newer NPIs suggest more recently credentialed providers), and Medicare billing data on NPIxray (does the billing pattern match what you know about the provider?).
NPIxray's billing data is particularly useful for verification. If you are looking for a specific cardiologist in Texas, seeing their Medicare billing summary (cardiology-related CPT codes, Texas-based payments) instantly confirms you have the right match.
Frequently Asked Questions
Can I search by first name only?
The NPPES Registry requires at least a last name for individual provider searches. First name alone will not return results. NPIxray similarly requires a last name or NPI number. For the best results, provide both first and last name plus the state.
What if the provider changed their name?
Providers are required to update NPPES within 30 days of a name change. If a provider married and changed their last name, the NPI Registry should reflect the new name. However, if the change is recent, you may need to search under both the old and new name. The NPI number itself never changes regardless of name changes.
Can I search for nurse practitioners and PAs by name?
Yes. NPPES contains NPI records for all covered healthcare providers, including nurse practitioners, physician assistants, physical therapists, psychologists, and many other provider types. The name search works the same way regardless of provider type.
