License Verification This tool allows you to check if a domain is authorized to be running WHMCS.


How to use this tool:
  • Enter only the domain name where WHMCS is installed
  • For example, if there was an installation at https://billing.example.com/index.php, enter just billing.example.com as the domain
  • The domain should not include the www. prefix
  • This tool leverages advanced techniques to verify the domain directly against the WHMCS database. Due to the complexity of this process, it may take up to 2 minutes to establish the connection and retrieve the results.
  • You can perform a verification every 20 seconds. If you don't wait for this interval, you might encounter an error message. Please be patient and wait before trying again.
  • Please note that this checker performs the same functions as the official WHMCS checker. It will not confirm that your license is original, but simply serves as a way to verify whether your WHMCS installation is recognized. If you think this doesn't offer much value, you're probably right. I created it as a hobby project to see if it was possible to obtain license validation through whmcsfull.com.
