What VeriflowAPI actually verifies

Federal screening, all 50 states

Two federal checks run on every verification regardless of the state:

Exclusion matching deserves a note, because name-only matching is what produces false positives in this industry. Roughly 90% of exclusion records carry no NPI, so a common name can collide with an excluded stranger. We use the identifiers you supply to resolve it: a matching npi or dob confirms an exclusion, a different one rules that record out as a different person, and a name-only match is reported conservatively rather than silently cleared. Sending a date of birth is the single most effective way to avoid a false exclusion on a common name.

State coverage at a glance

There are two shapes of source. A mirror means we hold a full copy of the state's published file and refresh it on a schedule, so lookups are instant. A live per-query state publishes no bulk file, so we query the board at the moment you ask and cache the result for 24 hours.

State by state

Which professions, in which states

We verify the underlying state licence. Board sub-certifications issued by national bodies rather than state boards — ABPN for psychiatry, ABPP or ABCN for clinical neuropsychology, BACB for behavior analysts — are separate national registries, so a psychiatrist is verified through their state medical licence and a neuropsychologist through their Licensed Psychologist licence.

What happens outside these states

A state we do not cover returns status: "unsupported_state" with verified: false. Federal NPPES and OIG results are still returned, so you get real identity and exclusion signal everywhere and route only the state-licence portion to manual review. We do not guess, infer or fabricate a state result, because a wrong confirmation is worse in a credentialing file than an honest gap.

Next on the roadmap: California disciplinary history and speech-language pathology through the DCA's iServices API, Georgia physicians, and FSMB national disciplinary data. If a state is blocking you, tell us — coverage is prioritised by what customers actually ask for.
