Postal Service Practice Exam 2025 – Comprehensive Study Resource

The criteria that determine whether an item can be mailed primarily includes minimum and maximum standards. These standards provide specific guidelines on the acceptable dimensions and weight limitations for items to be mailed. Adherence to these standards is crucial because they ensure that items can be processed efficiently and safely through the postal system. Each postal service has established these criteria to maintain the integrity of the mailing system, optimize handling, and eliminate potential delays caused by oversized or insufficiently sized packages.

While size and shape restrictions, weight and value considerations, and the type and destination of mail are also important aspects of mailing regulations, they fall within the overarching framework of minimum and maximum standards. These criteria ensure that all items comply with the necessary regulations before they can be accepted for mailing, which is key to ensuring a smooth postal operation.
