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.
