How to restrict default COD in magento to certain zip codes only?

Answer 1

All you need is to edit the file /app/code/core/Mage/Payment/Model/Method/Cashondelivery.php

Open it and add the code below to the very end of the class (just before the last “}” in the file):

public function isAvailable($quote = null)
{
    if ($quote) {

        // Here is the list of restricted Zip Codes
        $restrictedZips = array(
            '85001',
            '87965'
        );

        $address = $quote->isVirtual() ? $quote->getBillingAddress() : $quote->getShippingAddress();
        $customerZip = $address->getPostcode();

        if (in_array($customerZip, $restrictedZips)) {
            return false;
        }
    }

    return parent::isAvailable($quote);
}

P.S.: Note, that with this solution you will need to enter zip-codes right in the code. If you would like to avoid this, and get the ability to enter zip ranges via the admin's panel, contact us for more detail.
