NPI Tools

Free, no-clutter utilities for the people who actually use NPI numbers daily — credentialers, billers, recruiters, and healthcare sales. Built on the public NPPES registry.

NPI Validator

Paste a 10-digit NPI and verify it against the CMS Luhn check. Runs entirely in your browser — we don't log what you check.

Bulk NPI Lookup

Paste up to 50 NPIs at once. Validate each + link to the directory record. Email required (you get the Provider Pulse weekly digest).

Need more?

For batches over 50, custom specialty/geo segments, or NPPES data joined with verified emails and phones, Provyx delivers tailored CSVs.

About the data

Praxis MD mirrors NPPES with monthly bulk + weekly delta refreshes. Every page shows its source date.
