NPI number lookup

Search by NPI number, by provider name and state, or by organization name and state. The file is the September 2026 NPPES dissemination, through 13 September 2026.

Our data

Provyx counted every row in its copy of the NPPES monthly dissemination file for September 2026 (9,798,758 NPIs, records through 13 September 2026), joined to the deactivation report dated 14 September 2026. The figures below are aggregates from that file. They are not a live CMS query.

As of 13 September 2026. Active means the entity type is not blank and any deactivation date is followed by a later reactivation. Never updated means the last-update date equals the enumeration date. Not updated in 5+ years means the last-update date is on or before 13 September 2021. The 12-month window is 13 September 2025 through 13 September 2026. Shares are rounded to one decimal. Recompute from dataset.json, which holds these aggregates and the recipe.

How to look up an NPI

You can search three ways. Enter a 10-digit NPI number directly, or search by last name plus state (first name is optional), or search by organization name plus state. The number search is exact; the name searches return matching records in the file.

The result card shows the provider's name, NPI, record type, taxonomy, practice address and practice phone, enumeration date, last update date, and a staleness flag when the record has not been updated in a long time. If the record has a deactivation or reactivation date, that is shown too. When other NPIs share the same practice address, they are listed on the card.

NPI format and Type 1 versus Type 2

An NPI is 10 digits. The tenth digit is a Luhn check digit, computed with the prefix 80840, which is the CMS method. If a number fails that check, it is not a valid NPI.

Type 1 means an individual provider. Type 2 means an organization, such as a group practice or facility. The record type is shown on every result card.

How current the file is

This is not a live CMS registry query. It is the NPPES monthly dissemination from September 2026, with records through 13 September 2026 and the deactivation report of 14 September 2026. Weekly files after 13 September 2026 are not in this copy. From 13 September 2025 through 13 September 2026, 37,540 records have a deactivation date, and 36,070 of those are still deactivated. Separately, 2,251 records have a reactivation date in that window. That count is not the remainder of the 37,540.

A provider corrects an NPPES record at the CMS NPPES site (nppes.cms.hhs.gov), not on this page. Practice phone and practice address are the values in the dissemination file. They are not a verified direct dial, and they are not an email. Treat every result as a starting point and verify details before relying on them.

NPI versus other identifiers

An NPI, a DEA number, a state license number, and a taxonomy code are different identifiers that answer different questions. This tool searches NPI only. Taxonomy is shown on the result because NPPES stores it on the NPI record; it is not a license number.
