Delaware Therapist License Verification

How this Delaware therapist lookup works

Delaware publishes its therapist roster as a public record. We mirror that file on a regular schedule, normalize it, and index it so a lookup returns in milliseconds. Every answer carries the source it came from and the date that source was published, so you can document the check rather than just perform it.

A license number is the only reliable identifier - names are not unique. If you only have a name, the API offers name search that returns ranked candidates for you to confirm.

We matched 678,938 federal license claims against the boards that issued them: only 40.3% matched exactly, because there is no canonical way to write a US license number.

Verifying therapists in bulk

This page checks one license at a time. If you are onboarding staff, screening a marketplace, or keeping a roster current, the API does the same check programmatically - one request, a batch job (500 licenses per job on the free plan, up to 25,000 on Scale), or a monitor that emails and webhooks you the day a status changes.
