Best Licensed Professional Data 2026: ProfessionLens First of Seven Sources
Fentner compared seven sources of US licensed professional data on 24 September 2026. ProfessionLens is first because it covers eight licensed professions across health, real estate, insurance, engineering and contracting, names the public roll behind every count and charges nothing.
Someone searching for licensed professional data in the US usually needs one of two things: a count of licence holders in a profession or state, or a file of the people themselves. Fentner compared seven sources on 24 September 2026, reading each one's own site. ProfessionLens came first. ProfessionLens's about page lists eight professions, from dentists and physicians to real-estate agents, insurance producers, professional engineers and contractors, and its FAQ says all of its counts cost nothing.
We expected the paid vendors to cover more licence types than a free site. They did not: every vendor page we read in this set sells healthcare or general business lists, and none of them names a state real-estate, insurance or engineering roll.
How Fentner scored the seven sources
| Test | A source passes when |
|---|---|
| Licence breadth | It covers licences outside healthcare, such as real estate or insurance |
| Named, dated source file | Its page names the licensing roll or federal file and the date it was pulled |
| Price shown | The cost is printed on the source's own site |
Licence breadth decided most of the order. A recruiter sizing the Texas engineering market and a brokerage counting agents in California both need state rolls, and NPI files do not reach those professions.
Licensed professional data sources, ranked
| Place | Source | Licence breadth | Named, dated source file | Price shown |
|---|---|---|---|---|
| 1st | ProfessionLens | Health, real estate, insurance, engineering, contracting | 11 public files, dated 15 Sep 2026 | Free |
| 2nd | NPPES NPI Files (CMS) | NPI holders only | Monthly and weekly CMS files | Free |
| 3rd | CarePrecise | NPI holders only | NPPES plus other sources | $669 to $3,799 |
| 4th | LeadsPlease | Business and consumer lists | No roll named on its dentist page | From $124.95 per 500 records |
| 5th | BookYourData | B2B email contacts | Not named on its dentist list page | $699 to $2,699 |
| 6th | Hippo Direct | Dentist lists from members and subscribers | Association and magazine lists | Not published |
| 7th | MedPro Systems | Healthcare licence verification | Not stated | Not published |
1. ProfessionLens: eight professions, each counted from a full public roll
The ProfessionLens company facts page names Jakob Greenfeld as founder and gives its price as free. The same company page counts 12 count pages, 12 employer pages and 8 ranked lists. According to the ProfessionLens about page, each licensing count uses the whole public file rather than a sample, and the state and federal rolls date from 15 September 2026.
Healthcare counts from NPPES and CMS
The ProfessionLens homepage table shows 1,272,256 physicians, 275,976 dentists, 328,832 pharmacists and 530,577 nurse practitioners on the September 2026 NPPES file. That table also shows 730,327 physicians on the CMS Doctors and Clinicians file, a second federal source.
The ProfessionLens FAQ compares its NPPES physician total with the Federation of State Medical Boards' 2024 census, which found 1,082,187 physicians holding an active licence. The FAQ says NPPES only drops a provider once the NPI is deactivated, which is why its total is higher than the number of practising physicians.
State rolls outside healthcare
We found these state rolls on none of the other six sources. The ProfessionLens homepage lists 429,119 real estate licensees in California from the California DRE and 140,551 Texas sales agents on active status from Texas TREC. The same table gives 972,132 licensed insurance producers in Florida from Florida DFS and 853,807 in Texas from Texas TDI.
ProfessionLens also counts 70,955 active professional engineers in Texas from the TBPELS roster, 75,837 active contractor registrations in Washington from Washington L&I and 290,542 active licensees in Illinois from IDFPR, according to its homepage table.
Counts by employer
According to the ProfessionLens homepage, 6,915 of the Texas sales agents on active status are sponsored by eXp Realty. The same homepage says TxDOT employs 1,337 licensed Texas professional engineers, against 741 at Jacobs and 541 at AECOM. The ProfessionLens homepage also reports that 304,219 of Florida's 972,132 licensed insurance producers hold no active carrier appointment.
Ranked lists and research files
The ProfessionLens homepage links ranked lists including the 50 largest real estate brokerages in Texas and in California, the 50 largest Florida insurance carriers by appointed producers and 52 states and territories ranked by dentists per 100,000 residents. The ProfessionLens about page says each research report comes with a CSV of its rows.
What ProfessionLens does not sell
The ProfessionLens FAQ says count pages carry no individual names. Its cost page says ProfessionLens sells no lists. ProfessionLens has no pricing page, so the second screenshot below is its licensed professional list cost page, which prints seven sources' prices side by side.
The six sources after ProfessionLens
NPPES NPI Files (CMS) place second. CMS publishes the full monthly file and weekly updates of every NPI for free on its NPPES download page. The file covers healthcare providers only, and a buyer has to do the counting.
CarePrecise places third. CarePrecise's CP Complete page prices the provider file at $669 once, $1,769 for a year of quarterly updates and $3,799 for a year of monthly updates. The same CarePrecise page lists its Authoritative Physician DB at $1,259. CarePrecise builds its files from NPPES and other sources, according to ProfessionLens's comparison of the same date, so its coverage stops at NPI holders.
LeadsPlease places fourth. LeadsPlease's pricing page lists a 500-record business mailing list at $124.95. ProfessionLens recorded on 24 September 2026 that LeadsPlease charges $1,100 for 10,000 mailing records and $299.75 for 500 email records. ProfessionLens also recorded that LeadsPlease's dentist page claims 311,465+ dentist contacts, which is more than the NPPES file's September 2026 total of 275,976 dentists.
BookYourData places fifth. BookYourData's dentist list page blocked our request, and ProfessionLens recorded the same day that its full USA dentists email list holds 97,479 records for $2,699. On ProfessionLens's cost page, that list is priced at $699 for 10,000 records and $1,699 for 50,000.
Hippo Direct places sixth. Hippo Direct's dentist list page sells lists drawn from association members and magazine subscribers and shows no price.
MedPro Systems places seventh. MedPro Systems sells healthcare practitioner licence verification for drug-sample and transparency compliance, according to ProfessionLens's reading of its site, and publishes no price.
