NPIVerify

NPIVerify is a lookup tool for healthcare professionals who work with NPI numbers every day — credentialing specialists, provider network managers, revenue cycle teams, and anyone who needs to verify provider data without breaking their workflow. See an NPI on a webpage? Right-click it. Get the full provider record in under 3 seconds. Need to process a list? Paste up to 500 NPIs at once and download a single CSV. That's it. No new tab. No copy-paste into an external site. No account. No subscription. NPPES is a free public registry run by the U.S. Centers for Medicare & Medicaid Services (CMS), and NPIVerify gives you a direct line to it from wherever you're working. ────────────────────────────────────────────────── HOW IT WORKS ────────────────────────────────────────────────── Single lookup: 1. Select an NPI number on any web page 2. Right-click → "Look up NPI in NPPES" 3. The provider card opens instantly in a popup 4. Copy, export, or just read — no tab switching required You can also click the NPIVerify icon in your toolbar to search any NPI manually. Bulk lookup (new): 1. Click the Bulk tab in the toolbar popup 2. Paste up to 500 NPI numbers separated by commas 3. Click "Run bulk lookup" 4. Watch live progress as results are fetched 5. Download a single CSV when complete ────────────────────────────────────────────────── WHAT YOU GET ON EVERY LOOKUP ────────────────────────────────────────────────── For Individual Providers (Type 1): • Full name and credentials (MD, DO, RN, NP, PA-C, etc.) • Primary specialty with NUCC taxonomy code and state license number • Additional specialties • Primary practice address and phone • NPI issue date and last updated date For Organizations (Type 2): • Legal business name and DBA name • Organization type and primary specialty • Authorized official name, title, and phone • All practice locations (with "Show all" toggle for organizations with many sites) • NPI issue date and last updated date Both types include: • Active or Deactivated status • Data freshness indicator (see below) • One-click export to CSV and JSON ────────────────────────────────────────────────── BULK NPI LOOKUP — UP TO 500 AT ONCE ────────────────────────────────────────────────── The Bulk tab is built for teams that run high volumes of NPI verifications. Paste a comma-separated list of up to 500 NPIs, hit run, and NPIVerify handles the rest. How it works under the hood: • NPIs are validated locally before any API call is made — invalid format or check digit errors are caught instantly and flagged in the output, never wasting an API call • Duplicates are automatically removed before the batch starts • 10 concurrent workers run simultaneously so 500 NPIs complete in roughly 50 seconds • Each failed request is automatically retried up to 3 times with exponential backoff before being marked as an error • A live progress ring shows percentage complete, current count, and estimated time remaining The output CSV includes every NPI — successful lookups, skipped entries, and errors — in a single file: • Row_Type column: OK, SKIPPED, or ERROR on every row • Skip_Error_Reason column: explains exactly why a row was not fetched • 37 standard NPPES data columns (same schema as single-lookup CSV export) • 39 columns total The CSV opens directly in Excel and is compatible with standard credentialing and provider enrollment systems. ────────────────────────────────────────────────── DATA FRESHNESS — KNOW IF A RECORD IS CURRENT ────────────────────────────────────────────────── Every result — single or bulk — shows a color-coded freshness badge based on the NPPES "last updated" date: 🟢 FRESH — Updated within the last 6 months. Record is current. 🟡 AGING — Updated 6 months to 5 years ago. Consider re-verifying. 🔴 STALE — Not updated in over 5 years. Re-credentialing verification recommended. These thresholds align with standard healthcare re-credentialing cycles. You'll never wonder if you're looking at current data again. The freshness label is also included in every CSV export — single and bulk. ────────────────────────────────────────────────── RECENT LOOKUPS HISTORY ────────────────────────────────────────────────── The last 25 NPI lookups you run are automatically saved to a History tab. Each entry shows: • Provider name and NPI number • Type (Individual or Organization) • How long ago you looked it up Click any history entry to re-run a live NPPES lookup with one click. The history is stored locally on your device only — it never leaves your computer. ────────────────────────────────────────────────── EXPORT TO CSV AND JSON ────────────────────────────────────────────────── Single lookup — every provider card has one-click export: CSV — A flat-file export with 37 columns covering all NPPES fields. Opens directly in Excel. Ready for credentialing systems and data pipelines. Individual and Organization records use the same column structure — fields that don't apply are left blank, so you can combine records without reformatting. JSON — A structured export with all provider fields plus computed freshness data. Designed for developers building integrations with downstream systems. Files are named automatically: npi_[NPI]_[YYYY-MM-DD].csv / .json Bulk lookup — one CSV file covering the entire batch: All 39 columns (37 standard + Row_Type + Skip_Error_Reason). Every NPI in the input is represented — successful results with full data, and failed entries with a clear reason code. File named automatically: npi_bulk_[COUNT]_[YYYY-MM-DD].csv ────────────────────────────────────────────────── WHO USES NPIVERIFY ────────────────────────────────────────────────── ✓ Credentialing specialists verifying providers before onboarding ✓ Provider network managers checking current practice locations and bulk-verifying panel rosters ✓ Revenue cycle teams confirming NPI status before claim submission ✓ Heal…
