Shipping Zone

This is the edit and add form for shipping destination zones. It has the following fields:

• ID – this is the internal unique system ID of the shipping destination zone.
• Shipping type ID - this is the internal unique system ID of the shipping type.
• Zone Name – this is the label for the zone. This label is used in the cost table to identify the zone, and it is not visible anywhere on the storefront.
• COD Allowed – this checkbox controls, whether the COD payment type is allowed for this shipping destination. If COD is allowed in the shipping type selected during checkout, any enabled payment types marked as “COD” will be available on the billing step.
• Type – this is the type of the destination zone. Zones can be defined by country, by state and by zip code. For country zones, the administrator can select any set from the predefined list of countries. For state zones, the administrator chooses one country, and then he or she can select a set of states in that country. For zip-code (postal code) based zones, the administrator has to select the country, and then select a subset of zip codes from the list. If a specific code is not on the list, it can be added using the field below by pressing “Add location”. The list of zip codes is built on the fly from all zip codes used in any zone across all shipping types (it is not practical to maintain it by the system). Note that a zone cannot be of a mixed type, and if you switch the zone type you will loose the information entered for the previous type (for example, if you entered 5 zip codes for a zip-code based zone, then switch the type to country-based, and then switch back to zip-codes, the 5 entries will be gone).
