9ID is a contractor management platform that automates compliance verification and workforce access control for organizations managing external workers and contractors at physical sites. The platform digitizes the process of verifying contractor credentials, certifications, and compliance documentation before site arrival. The system collects and verifies required documents and information from contractors and subcontractors in advance, storing them in a centralized digital repository. It provides site owners with visibility into all contractors and subcontractors across multiple locations, enabling verification of who is on site at any given time. 9ID automates compliance workflows by sending automatic reminders to contractors for training renewals and document expirations. The platform maintains a complete audit trail of all contractor documentation, enabling organizations to quickly provide required records during audits or inspections. The solution addresses contractor registration and check-in processes, reducing manual administrative work and wait times at site entry points. It supports global deployment with standardized processes across multiple sites while allowing for local customization to meet regional regulatory requirements. Organizations use 9ID to manage contractor compliance across industrial facilities, corporate campuses, and other secured locations where third-party workers require verified credentials and safety certifications before accessing premises.
