More about this list

Built from the CMS National Plan and Provider Enumeration System (NPPES) monthly file, the NPPES deactivation report, the NUCC provider taxonomy and the CMS Care Compare Doctors and Clinicians national file. Every deactivated NPI is removed — 351,911 of them — rather than shipped as an empty row, and the address is the practice location, never the mailing address. Coverage is 1 states and territories.

✓Where this data comes from

This dataset is built from the CMS National Plan and Provider Enumeration System (NPPES) monthly file — the federal registry every billing provider must maintain — with the NPPES deactivation report applied so retired NPIs are excluded, specialties resolved against the NUCC provider taxonomy, and Medicare participation joined from the CMS Care Compare Doctors and Clinicians national file. Nothing here comes from a provider's own website; every record is the provider's own registered entry.

Fill measured

On every row of the delivered file

Deactivated NPIs are removed using the CMS deactivation report, specialties are resolved against the NUCC taxonomy rather than kept as raw codes, and addresses are validated to US bounds and ZIP format. Records are otherwise published as registered — the federal file is the record of truth, and correcting it would make the dataset disagree with the source buyers reconcile against.

How we build and date every file: methodology.

Using ChatGPT, Claude or an API?

No setup needed. Ask ChatGPT or Claude your question about the California Healthcare Organizations and give it this page: it can open https://locationlists.com/find?dataset=california-healthcare-organizations with the filters you need and show you the count and price.

Using ChatGPT or Claude? Tell it to answer from locationlists.com/find — no account, no connector.

How assistants ask

No connector needed. Any AI assistant can answer from this site with a web link, no connector, no account: open https://locationlists.com/find with the question as query parameters.

If a question needs filtering, distance, drive time, combining lists or a price, open a /find link: either put the question itself in q=, or build the structured link. The answer does not need an API, a connector or an account.

Simplest, the question itself: https://locationlists.com/find?q=<the question in plain words>

Or set the parts yourself: https://locationlists.com/find?dataset=<slug>&state=<ST>&city=<city>&county=<county>&zip=<zip>&near=<place or zip>&radius=<miles>&drive=<minutes>&where=<column>:<op>:<value>&total=<rows>

Leave out what the question does not need. Use radius for straight-line miles or drive for minutes of driving (5 to 60), not both; near can name several places separated by | to reach from any of them. To ask about several lists at once, use datasets with two or more names, or category with a kind of business. To compare two lists, add relate=nearest and the other list with b. in front of its parameters. To count by area, use areas=county (or zip, state, metro). To keep only places whose county, ZIP code, metro area or state meets a Census figure, add area_where (for example county:population>1000000); with areas, per=100000 gives counts per 100,000 residents.

Links an assistant can open, each showing how many rows match, a few preview rows and the price for just that part:

Optional: connect for repeat use or wallet payments:

Read https://locationlists.com/skill.md and follow the instructions to connect LocationLists. Then show me the California Healthcare Organizations list.

Your assistant will walk you through setup and show you the price before you pay.

For developers

Every step below has a no-connector equivalent: https://locationlists.com/find?dataset=california-healthcare-organizations with the same filters as query parameters.

  1. Connect your agent to https://locationlists.com/mcp (no key, no signup).
  2. Call count_locations with dataset: "california-healthcare-organizations" and any filter — it is free, and returns how many rows match and what they cost.
  3. Fetch the rows with query_locations: $0.08 per 100 rows from this dataset. Above 98,154 rows, buying the whole file is cheaper.

Paid in USDC over x402 — the agent gets an HTTP 402 with the exact price, signs, and retries. Money moves only after rows are delivered, so a failed or empty query costs nothing. Setup for Claude, Cursor and VS Code

?Frequently Asked Questions

How many Healthcare Organizations are there in California?

There are 196,307 Healthcare Organizations in California as of September 2026.

Where does this data come from?

The CMS National Plan and Provider Enumeration System — the federal NPI registry — plus the NUCC provider taxonomy and the CMS Care Compare clinician file. All three are published by the government and free to download; what you are buying is the parsing, the taxonomy decode, the deactivation cleanup and the cut. Every vendor selling an NPI-based list is working from the same files.

Are these businesses or individual people?

Organizations only — practices, clinics, agencies and facilities at their business address. Individual providers are sold separately so the two are never mixed.

One address sometimes has several NPIs. Does that inflate the count?

It can, and the file tells you: npis_at_address counts how many NPIs share each practice address. NPPES enumerates billing entities rather than premises, so a practice may carry one NPI per owning PLLC. Filter on that column to get sites.

Is this the same data Definitive Healthcare or IQVIA sell?

The registry underneath is the same public CMS file. What those vendors add on top is their own layer — hospital affiliations they research, executive contacts, claims-derived volumes, purchasing intent. If you need that, buy them. If you need the registry itself as a file you own, this is it, at a fraction of a subscription.

Does this include email addresses?

No, and no honest NPI-based product does — NPPES has no email field. What it does have is the Direct secure-messaging address that some providers register for clinical data exchange, and those ship in their own column, labelled, because they are not marketing addresses. Any vendor selling you a 'physician email list' built on NPI data appended those emails from somewhere else.

How current is it?

File built on September 15, 2026. It is not on an automatic refresh schedule, so check the build date above before you buy.

What format is the download?

A single UTF-8 CSV with a header row, one row per NPI, ready for Excel, a CRM import or a database load. Commercial licence, one-off purchase, no subscription.
