This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



This domain check plugin allows checking if a domain name is available. Checking
if a domain name is available is a complex problem. New top level domains
emerge frequently. Static domain check codes get outdated very soon. This plugin
uses the Whois API to support the
latest top level domains correctly. By using the Whois API you also avoid
hitting any rate limits on the respective whois server.


  1. Upload the domaincheck folder to the /wp-content/plugins/domaincheck directory,
    or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress.
  3. Set in Settings/Domain Check the api key from the Whois API.
  4. Add the widget to your prefered location through the ‘Appearance’ menu in WordPress.
    or add shortcode [domaincheck] to your post or page.

The shortcode [domaincheck] supports these parameters

  • button (optional): Text of the submit button, e.g. [domaincheck button=Check]
  • available (optional): Message shown when a domain is availbale. It supports the
    placeholder %s for the domain, e.g. [domaincheck available=”The domain %s is available”]
  • registered (optional): Message shown when a domain is registered. It supports the
    placeholder %s for the domain, e.g. [domaincheck registered=”The domain %s is not available”]
