A shipping zone is a geographic location where a certain set of shipping methods and rates apply. You can add as many shipping zones as you need as customers can see the methods available for their address only.
Shipping zones are introduced in WooCommerce version 2.6 to bring more flexibility while configuring your shipping methods. Legacy shipping methods (Flat Rate, International Flat Rate, Local Pickup and Delivery, and Free Shipping) are rejected. So, it’s highly recommended to you disable these and setting up new rates within shipping zones as soon as possible.
