What do I need to do if I want to implement signing up of users with scratch code as much as 60,000 units? Want the site to auto validate if the code entered is valid and not used already.

  Hello DeDiary !
  It will require to have the Javascript block which will contain the AJAX request to check the entered ZIP code. And PHP file (or request to some module's method) to process this request.
