Postal Zones are assigned by USPS based on the distance a piece of mail travels from its shipping origin to its destination. Postal zones can help you determine the shipping cost and estimated delivery date. By default, postals zone are included in the Orders module in the Zone column, which allows you to sort orders by postal zone and apply bulk actions to those orders.

If you don't see the Zone column, click on the icon below in the bottom left corner of the Orders grid to choose the columns you want to show or hide from view, in addition to their placement.
