  • This component will not 100% detect if a given postal code exists or not

This component uses Zend_Locale to get the postal code informations for all known countries. These are then used to detect if the given input is a postal code or not. This component can not detect if a given postal code exists or not. It only checks if a given input can be a postal code, if the notation conforms, or not.

    <p>Do you need help for checking GB postcodes?</p>

    1. Sep 09, 2009

      <p>No need to check. The component is already finished.</p>

      <p>The data comes from unicode.<br />
      When it's not correct then we have to blame unicode <ac:emoticon ac:name="wink" /></p>

      <li>Code is finished</li>
      <li>Unittests are finished</li>
      <li>Documentation is finished</li>

      <p>There is nothing to do as all work is already done.<br />
      We are just waiting for approvement from the dev-team.</p>
