NPI entity resolution

Match messy provider rows to the right NPI.

NPI entity resolution is the precise version of bulk NPI lookup. It decides which Type 1 or Type 2 NPI belongs to the provider or organization in each row, then shows the evidence.

Quick answer

NPI entity resolution finds and verifies the NPI record for a healthcare entity, then explains why it is the right match. NPI Finder starts with NPPES, verifies candidates, separates individuals from organizations, and returns confidence-rated results with evidence.

The hard part

A clean identifier for messy entities.

A spreadsheet row may contain credentials, nicknames, stale addresses, a marketing name, a DBA, or only a partial organization name. NPI entity resolution has to bridge that input to a specific registry record.

Individual providers may appear under nicknames or reversed name order.
Organizations may register under legal names, DBAs, former names, or location-specific entities.
A known NPI hint still needs check-digit and registry verification.

Confidence

High confidence requires more than a name.

A plausible name match is the gate. Address, ZIP, phone, city, state, and specialty then support the match and shape the confidence grade.

A matching street or ZIP can support high confidence.
City and state may be useful but weaker.
Missing location data caps how certain an automated result should be.

Workflow

Every match shows its evidence.

Identify the expected NPI type

Infer or enforce whether the row should resolve to an individual provider or an organization.

Search NPPES candidates

Use the registry for names, organization names, state, and NPI hints before escalating to public web sources.

Reject lookalikes

Do not choose co-tenants, same-address practices, or different organizations just because they share a location.

Return evidence

Include the matched NPI, registry name, address, confidence, reasoning, candidates, and source URLs.

Signal

Type safety

Lets a person NPI satisfy an organization row.

Keeps Type 1 and Type 2 resolution explicit.

Verification

Accepts any 10-digit number found online.

Checks the NPI number and verifies the record against NPPES.

Evidence

Returns only the selected NPI.

Shows why the NPI was selected and what other candidates were considered.

Common questions

NPI entity resolution matches a healthcare person or organization record to the NPI record that belongs to that entity.

Type 1 NPIs identify individual providers. Type 2 NPIs identify organizations such as practices, clinics, hospitals, and facilities.

Yes, but confidence may be lower because there are fewer supporting signals. NPI Finder still uses registry and public evidence to decide what it can support.
