Best licensed professional data sources in 2026
Read 28 October 2026
11 sources of data on US licensed professionals, from free licensing files to paid contact lists. They are ranked by how many licensed professions each covers, then by whether it names the licensing file behind its numbers. Prices and claims are from each source's own site on 28 October 2026; file sizes are from our September 2026 downloads. ProfessionLens is our site.

1. ProfessionLens
ProfessionLens counts licensed professionals from full public files: the September 2026 NPPES file for healthcare, and state rolls such as Texas TREC, California DRE and Florida DFS for real estate and insurance. Every count page names its file and the date it was pulled. The site sells California, Texas and Florida real estate agent lists at $29 each and a Texas insurance agent list at $249. It has no email addresses or phone numbers. Pricing · All counts
2. State licensing boards
The boards that issue licences are the source behind every other entry here. Some publish the whole roll as a free download. Texas TREC's broker and sales agent file had 324,715 rows on 14 September 2026. California DRE's current licensee list had 429,119 licensees, with postal addresses. Florida DFS rebuilds its file of 1,236,929 valid individual insurance licences every day. Other boards publish only a name search: we found no bulk file for the California or Texas State Bar or the Illinois Department of Insurance. Each board uses its own columns and status codes, and a licence row is not a person: the Texas insurance file has 1.13 licence rows per producer. data.texas.gov
3. NPPES NPI Files (CMS)
CMS publishes the full NPPES file every month, with weekly update files in between. The September 2026 file had 9,798,758 rows, including 275,976 dentists. It covers every provider who bills with an NPI and nothing outside healthcare. Deactivated NPIs stay on the file and one person can carry up to 15 taxonomy codes, so a count needs filtering first. cms.gov
4. ARELLO
ARELLO, the association of real estate licence regulators, runs a lookup fed by its member jurisdictions, most of them daily. Its site lists 4,342,569 real estate licence records, of which 2,934,148 from 43 jurisdictions are searchable through the API. The rest are National Association of Realtors records, which its agreement with NAR allows only in the manual search. The API starts at $300 a month. ARELLO states it offers no bulk download because of conflicts with member jurisdictions. arello.com
5. NIPR Producer Database
NIPR reports 9.2 million producer records in its database. Those are licences, not people. Its Producer Database shows each producer's licences and appointments across states. Batch reports and alerts need a subscription, and NIPR publishes no price. A producer gets one free detail report a year, after identity checks. nipr.com
6. CarePrecise
CarePrecise packages the NPPES file with other government and private sources. CP Complete costs $669 once, $1,769 for a year of quarterly updates and $3,799 for a year of monthly updates. Its Authoritative Physician DB is $1,259. Email addresses for physicians, nurses, dentists and others start at $250. It covers NPI holders only. careprecise.com · ProfessionLens vs CarePrecise
7. Definitive Healthcare
Definitive Healthcare sells subscriptions to its physician (PhysicianView), hospital (HospitalView) and claims (Atlas) databases. Its pricing page has no prices: plans are quoted per product, licence and add-on after a form. It covers healthcare only. definitivehc.com
8. LeadsPlease
LeadsPlease sells lists by the record. A business mailing list costs $124.95 for 500 records and $1,100 for 10,000. Business email lists cost $299.75 for 500 and $2,800 for 10,000. Its dentist page advertises 311,465 dental contacts, more than the 275,976 dentists on the September 2026 NPPES file, and names no licensing source. leadsplease.com · ProfessionLens vs LeadsPlease

BookYourData's USA dentists email list has 97,479 records: $699 for 10,000, $1,699 for 50,000 and $2,699 for all of them. That is 35% of the 275,976 dentists on the September 2026 NPPES file. Custom builds start at $499 for 1,000 records. The list page names no licensing source. bookyourdata.com · ProfessionLens vs BookYourData
