# Zip Code Validation Bug (Greece)

 * Hi Packlink Support Team, I am writing to report a critical issue with the Packlink
   PRO shipping plugin for
 * WooCommerce/WordPress that is currently disrupting my store’s checkout process
   for clients in Greece.
 * The Technical Issue:My clients are unable to complete their orders because the
   validation logic in the plugin does not recognize standard 5-digit Greek zip 
   codes unless a space is manually inserted.
 * Failure Case: If a client enters a zip code like 10447, the system rejects it
   as invalid and blocks the shipment.
 * Success Case: The system only accepts the address if the user adds a space (e.
   g., 104 47).
 *  Since most Greek customers naturally type their postal code as a single 5-digit
   string, this is causing significant friction and abandoned carts at checkout.
 * I have screenshots from my WordPress backend and the customer-facing checkout
   page showing this validation error in action.
 * Could you please update the plugin’s validation logic to ensure that Greek zip
   codes are recognized both with and without spaces?
 * This needs to be resolved ASAP as it is directly impacting my sales and my clients’
   ability to ship.
