Yes. The Trillium Provider Onboarding Solution Portal is fully HIPAA-compliant. All data transmission is encrypted, and submitted documents are stored securely in accordance with federal healthcare privacy regulations.
A government-issued ID — such as a Driver's License or State ID — provides a trusted, consistent way to confirm that a real, authorized individual is completing enrollment on behalf of an agency. These IDs contain verifiable information that can be checked through automated identity-verification technology, helping protect the platform against fraud and impersonation.
Yes. Many platforms that handle sensitive transactions — including LinkedIn, Airbnb, Uber, and others — use government ID verification to reduce fake accounts, prevent impersonation, and maintain the integrity of their platforms. Trillium requires it for the same reasons: to protect providers, payers, and the people we serve.
Verification checks basic identifying details — name, date of birth, license validity, and security features such as barcodes and document formatting. This is done through automated identity-verification technology; a person does not manually review your ID image.
Submitted documents are stored securely in accordance with federal healthcare privacy regulations, including HIPAA. If you have specific questions about document retention, please contact our Provider Onboarding Support team.
