Magento Post Code Filter Extension

Only allow customer groups with a shipping address within a specific postcode list to place orders.

Description

When installed, the administrator can manage Post Code Filter rules in the admin area under the Customer menu item.

Each Post Code Filter consists of

• a country (from a select input field)
• one or more customer groups (from a multiselect input field)
• a list of postcodes (comma or newline separated list of records in a text area input field)

The filter rules are applied during checkout as follows:

1. If a filter rule exists for the shipping address country and the customers customer group, and the shipping address postcode is within the associated list of postcodes, allow order placement.
2. If a filter rule exists for the shipping address country and the customers customer group, but the shipping address postcode is not within the associated list of postcodes, deny order placement.
3. If no filter rule exists for the shipping address country and the customers customer group, allow order placement.

The third rule might be confusing at first, but the idea is to create a rule for all allowed countries for the NOT LOGGED IN (a.k.a guest) and General customer group, and then the all other customer groups automatically become reseller groups to whom them filter rule do not apply.
