What You Can Verify

Eazelo checks public identity evidence from NPPES/NPI and then attempts to reconcile that evidence with the mapped Washington licensing source. The proof report can include NPI status, taxonomy, public practice-location context, state license evidence, source URLs, timestamps, and a checksum.

NPI evidence helps identify the provider and reported taxonomy, but an NPI does not itself prove licensure. State license status must come from the issuing board, state professional licensing portal, Nursys where applicable, or another official or approved source.

Current automation seed: Tier 1 DOH/open-data connector. DOH provider credential search/open data is the all-provider seed; confirm profession fields.

NPI Registry And Taxonomy Check

Eazelo uses NPPES/NPI evidence to compare provider identity, taxonomy, and any provider-reported state license values against the selected state-license source. If NPI and state-license evidence disagree, the report keeps the discrepancy visible instead of treating it as a verified match.

When Manual Review May Be Needed

Manual review may be needed when a source requires visual verification, a license search is gated, NPI and state-license numbers disagree, the selected provider type uses a separate board, or the state source does not return enough comparable fields for an automated result.

For paid change-request validation or bulk company workflows, Eazelo can preserve the submitted context and route the case into a reviewed workflow after signup.

Frequently Asked Questions

How do I verify a provider license in Washington?

Use the official Washington licensing source for the provider type — Washington provider credential search — or run an Eazelo public check, which compares NPI Registry identity and taxonomy evidence with the mapped Washington source and generates a watermarked proof report.

What is the official Washington license lookup website?

Washington provider credential search: https://doh.wa.gov/licenses-permits-and-certificates/provider-credential-search. DOH provider credential search/open data is the all-provider seed; confirm profession fields.

Is an NPI number the same as a Washington license?

No. An NPI is a national identifier from the NPPES registry and helps identify the provider and reported taxonomy, but it does not itself prove licensure. Washington license status must come from the issuing board, the state professional licensing portal, Nursys where applicable, or another official or approved source.

What does an Eazelo proof report include?

A public check generates a watermarked report with source URLs, timestamps, source-status details, and a checksum when enough source evidence is available. Anyone can confirm the report is genuine using its report ID and verification code on the Eazelo report verifier.

Do I need an account to run a Washington provider check?

No account is required to start a public check within the anonymous allowance. Creating a free account saves your request history, reports, and call plans.
