A Region is a set of rules that allow you to target specific areas within the countries that make up your Shipping Zones. When an order is received that has a destination address within a country that is covered by one of your Shipping Zones, the Regions for the Shipping Zone determine which Rates should be used.
Acme Inc. has set up a Zone for Australia. They wish to have a set of rates for:
Addresses in downtown Sydney,
Suburban addresses in the outskirts of Sydney
Addresses elsewhere in Australia
Acme Inc. create three Regions for this Zone. The first has rules that target postcodes in central Sydney. The second has rules that target only suburban addresses in Sydney. The last Region is a ‘catchall’ that would automatically capture any postcodes that fall outside the rules set up in the first two Regions.
Regions offer a great deal of flexibility, allowing you to target very specific areas to broad, country-spanning regions. Understanding how to set up Regions and which targeting rules are most suitable in which situations will greatly help you when creating your shipping rules.
