Product Description:

Ajax Duplicate Alert is a GeoDirectory add-on that keeps your database free of duplicate entries. It checks several fields of new listings in real time against the listings already in the database.

When an enabled field matches a current entry, the user sees a warning notice before they add a duplicate. Turn each field on or off: post title, address, zip or post code, phone number and email address. Each field’s error message can be customized, or it falls back to a general warning message.

With the Custom Post Type add-on, each post type has its own settings and error messages.
