Free NPI tools for US healthcare
Three free tools from Hewto.ai to work with National Provider Identifiers: validate NPIs against the live CMS NPPES registry, generate checksum-valid fake NPIs for testing, and look up any provider's NPI by name. No signup, no API key, nothing stored.
Why we built these NPI tools
Hewto.ai automates healthcare document processing — claims, enrollment forms, and EDI. NPIs sit at the heart of all of it, so we built the tools we wished existed and made them free for the whole industry.
Instant, no friction
No accounts, no API keys, no rate-limit anxiety. Open a tool, get your answer, get back to work.
Official data sources
Lookups hit the CMS NPPES registry live — the same source payers, clearinghouses, and RCM platforms trust.
Built by claims people
The same team behind Hewto.ai's claim-form extraction platform — these tools follow the exact CMS rules your billing software enforces.
