What categories fall under mailing zones?

The categories that fall under mailing zones are typically concerned with how mail is categorized for shipping costs based on distance, size, and weight. In this context, dimensional weight and balloon are terms associated with determining shipping rates based on the dimensions of packages rather than their actual weight. Dimensional weight takes into consideration the volume of the package, which can adjust the pricing structure significantly. Balloon rates apply to lightweight packages that have a larger volume, designed to account for the extra space they occupy.

This understanding is crucial for sales and service associates as it informs them of how pricing works in relation to shipping services. It helps in providing accurate information to customers about shipping costs and options based on the characteristics of their packages.
