We believe in making background screening simple, by delivering personalized support and innovative tech, wherever you do business.
Verifications & References
As a leading employment verification service provider, our professional and personal reference checks gather critical information regarding character, experience, work ethic, dependability, and capability. Through the use of a combined method including traditional phone calls, automated emails, and text messages, we complete employment verifications and references from all angles with high completion rates and quality responses.
DOT Employment Verification
Employers covering the past three years are contacted and the verification incorporates the DOT required questions for each employer. The questions include accident history and drug and alcohol information. Our DOT employment verification includes the requirements set forth by DOT to satisfy Section 391.23 of the Federal Motor Carrier Safety Regulations and complies with 49 CFR Part 40.25.

Confirm dates of enrollment, date degree/diploma received, GPA, and educational credits. Information released depends upon individual institution policies. Accreditation checks are available and encouraged as part of the verification process to combat the use of diploma mills.
