FAQ
General
What professions does VeriflowAPI currently support?
VeriflowAPI screens providers in all 50 US states via NPPES (identity/NPI) and OIG (federal exclusions), with deep state-level license data for thirty states: Texas, Florida, Illinois, Washington, Colorado, Connecticut, Alabama, New York, New Jersey, Delaware, Pennsylvania, Ohio, California, Massachusetts, Michigan, Rhode Island, the District of Columbia, Kansas, Vermont, Wyoming, Idaho, Mississippi, Maryland, New Mexico, Louisiana, Iowa, Arkansas, Kentucky, West Virginia and Oklahoma. Across those states we verify 53 licensed professions — physicians and advanced practice, behavioural health, the full nursing register, rehabilitation and therapy, dental, pharmacy, vision and diagnostics, and public and community health. No single state covers all 53; the role matrix shows which state covers which, and every response carries aprofessions_covered list for the state you asked about.
Additional states and professions are added based on demand. Email support@veriflowapi.com to request priority support for a specific profession.
How accurate is VeriflowAPI?
VeriflowAPI pulls directly from authoritative government databases — NPPES, OIG, and state medical boards. Accuracy is as good as the source data. We normalize and validate data on ingestion to reduce errors from inconsistent source formatting. For high-stakes decisions, we recommend using both NPI and DOB in your request to maximize match accuracy.Can VeriflowAPI verify providers in all 50 states?
Yes, for federal NPI and OIG screening (nationwide). For full state-level license status — including expiry date and disciplinary history — we currently support thirty states: Texas, Florida, Illinois, Washington, Colorado, Connecticut, Alabama, New York, New Jersey, Delaware, Pennsylvania, Ohio, California, Massachusetts, Michigan, Rhode Island, the District of Columbia, Kansas, Vermont, Wyoming, Idaho, Mississippi, Maryland, New Mexico, Louisiana, Iowa, Arkansas, Kentucky, West Virginia and Oklahoma. Other states returnstatus: "unsupported_state". Additional states are added based on customer demand.
Do you support international license verification?
Not currently. VeriflowAPI is focused on the US market. Canada and UK are on the roadmap for 2027.Technical
What happens if a government site is down?
VeriflowAPI serves cached data when a source is temporarily unavailable. The response will include"cached": true and "source_live": false. The cache_expires_at field tells you when fresh data will next be attempted.
Our 99.9% uptime SLA covers our API availability, not the availability of individual government source sites.
How do I know if my result is from cache or live?
Check thecached and source_live fields in the response:
What does verified: false mean exactly?
verified: false means one of the following:
- Provider was not found in any checked sources (
status: "not_found") - License status is not active (
status: "inactive","suspended","expired", or"revoked") - Provider is on the OIG exclusion list (
oig_excluded: true)
status and oig_excluded fields for the specific reason.
Can I use VeriflowAPI for non-medical professions?
No. VeriflowAPI covers healthcare licensing only, and every verification is restricted to healthcare licences deliberately: several states publish one register for every licensed occupation, so without that restriction a name could match a realtor or a liquor licence. Within healthcare the coverage is broad — 53 professions, including the full nursing register, pharmacists and pharmacy technicians, dentistry, optometry and podiatry, not just physicians. Legal and contractor licensing is not offered.What is the difference between disciplinary_flags and oig_excluded?
disciplinary_flags: truemeans the provider has disciplinary actions on record with their state medical board. This could be a warning, probation, or other board action. It is a signal that requires human review — not necessarily a disqualifier.oig_excluded: truemeans the provider is on the federal HHS exclusion list. This is a hard disqualifier. You cannot employ or contract with this provider if you receive federal healthcare funding (Medicare, Medicaid).
