Whose CAGE code should be included in the sponsorship letter?

The correct choice emphasizes the importance of including the CAGE code of both the cleared prime contractor and the uncleared contractor in the sponsorship letter. This is critical in the context of facility security clearance requests, as the presence of both codes serves to establish clear connections between the contractors involved in the project.

Including the cleared prime contractor's CAGE code helps to validate that there is an authorized entity overseeing the project, which is a requirement for compliance with security regulations. The uncleared contractor's CAGE code is equally important because it signifies their association with the project and clarifies the nature of the relationship between the contractors. This dual inclusion enhances transparency and provides a comprehensive overview of all parties engaged in the work, which is essential for security clearance processes.

In contrast, omitting either code could hinder the understanding of contract scope and responsibilities among various contractors, potentially leading to compliance issues. Therefore, the decision to require both codes reflects a thorough approach to security within collaborative contractor environments.
