Which term refers to the policies governing internal operating procedures for postal services?

The term that refers specifically to the policies governing internal operating procedures for postal services is the Postal Operation Manual (POM). This manual is an essential document that outlines the procedures, standards, and responsibilities that postal employees must follow to ensure efficient and effective service delivery within the postal system. The POM serves as a comprehensive guide that facilitates training, compliance, and consistency across various postal operations.

While other options may seem relevant, they do not encompass the full scope of internal operational procedures as comprehensively as the POM. Operational Guidelines might refer to specific instructions or recommendations that help staff perform their duties, but they may not cover all aspects of the internal operations comprehensively. Postal Service Regulations pertain to broader rules and legal requirements that govern postal services and may not focus specifically on internal procedures. District Operations Manual may refer to guidelines specific to a particular district within the postal service but may not include the overarching procedures applicable across all districts. Thus, the Postal Operation Manual clearly addresses the question of internal operating procedures for postal services.
