What are the three types of parcels in postal services?

The three types of parcels in postal services are classified based on their handling requirements and physical characteristics. Machinable parcels are those that can be processed by automated machinery, which typically have certain dimensions and weight limits that allow them to move efficiently through sorting systems. Non-machinable parcels do not meet these requirements due to their size, shape, or weight, requiring manual handling, which can lead to higher shipping costs. Irregular parcels may not fit standard measurements and often require special handling due to their unique characteristics.

Machinable, non-machinable, and irregular categories help postal services streamline operations by categorizing parcels based on how they can be processed and handled, which is crucial for maintaining efficiency and delivery timelines.
