What is the purpose of access control in CTPAT?

• A. To track shipments
• B. To ensure positive identification of all employees, visitors, and vendors at all points of entry
• C. To identify packaging materials
• D. To manage inventory levels

Answer: (B)

Access control in CTPAT is about who is allowed to enter and move within secure areas, so the main idea is ensuring positive identification of all personnel and visitors at entry points. When a facility verifies identities with badges, credentials, background checks, and keeps visitor logs, it confirms that anyone entering restricted spaces is authorized, which helps prevent unauthorized access, tailgating, and insider threats. This creates an auditable record for accountability and incident response, and it supports the broader goal of physical security within the supply chain. The other activities—tracking shipments, identifying packaging materials, or managing inventory—address different security or operations aspects and do not directly ensure that only approved people can access sensitive areas.
