For individuals designated as SCI couriers, the requirement to be appointed in writing is crucial. This written appointment ensures that there is a formal record of the individual's authority and responsibilities as a courier for Sensitive Compartmented Information. It serves to establish clear lines of accountability and delineates the scope of the courier's duties. Having a formalized appointment helps maintain security protocols and ensures that those entrusted with transporting sensitive information are authorized and recognized within the structure of the agency, organization, or military branch involved.

The other requirements, while important in various contexts, may not be as strictly mandated as the need for a written appointment. For example, a verbal agreement lacks the formality and traceability of a written one. Background checks are essential for personnel handling sensitive information, but they are not unique to couriers nor sufficient alone without the proper appointment documentation. Prior experience may be beneficial, but it is not a formal requirement and does not replace the necessity of a written appointment. Therefore, the requirement for SCI couriers to be appointed in writing is central to ensuring that the handling and transfer of sensitive information are conducted securely and legitimately.
