Add this code on the OnePageCheckout Controller(IndexController.php):

$billing_data = $this->getRequest()->getPost('billing', array());

and get the Zip Code:


as you wish to use it on other module, just set it on the core session:


and Get value from session in your module like:

$zipCode = Mage::getSingleton('core/session')->getZipCode();

this will allow you to get the Zip Code whenever the user is done inputting.
