How are Postal Service handbooks identified?

Postal Service handbooks are identified by a combination of letters and numbers. This system enables precise categorization and easy reference for employees. Each handbook is assigned a unique alphanumeric code that reflects its content and purpose, effectively distinguishing it from other handbooks within the Postal Service.

This method of identification is practical, as it consolidates information associated with various functions and compliance requirements into a concise format that can be quickly referenced. Other options such as color codes or geographical locations do not contribute to a systematic approach for identifying handbooks, and while publication dates can be useful for tracking updates, they do not serve as the primary identifier for the handbooks themselves.
