This is a simple plugin that adds a shipping zone column in the orders administartion menu. 
It displays in that column the zone name based on postal codes.
To make this plugin work. 
Suppose you have two or more warehouses and you need to know which is the right warehouse to ship your products based on shipping address postal code. 
This intelligent order plugin will make this happen. First you need to create shipping zones based on postal codes. Give them a unique name. 
Add any shipping methods and costs as you like. Now you are able to see the shipping zone that an order belongs. 
It works with new and old orders.
This plugin doesn’t have any configuration page. The only configuration needed is the description above which belongs to the 
woocommerce core functionality.
Full woocommerce compatible.

This is a plugin to customize your states. After the introduction of Shipping Zones by Woocommerce and as not all countries have implemented the zip-code system, you may need to add custom states or even split some states under regions to easily use in Shipping Zones configuration. This is what exactly this plugin do.
The FREE version will allow you to choose any country you already stated in your Woocommerce settings as ‘Allowed Country’ to sell and ship to, and add any number of states you want. Very simple and straight forward.
The PREMIUM version will allow you to add any number of states to any country you identified as ‘Allowed Country’ in your Woocommerce store setup. Also, it will allow you to manipulate the states that already come with Woocommerce for some countries such as the US. You will able to add or delete as you see required.
The beauty of this plugin that it doesn’t change the main states files that come with Woocommerce and you can always revert to original states by deactivating the plugin if you want at any time.
The free version is free to use with any number of sites and any number of states but just for a single country as stated earlier.
Please, if you find this plugin helpful, consider to buy the premium version which will help us to continue the development and provide you with new plugins. 🙂
