According to the standard, the license must be publicly available on the site so that players can familiarize themselves with it. If it is missing, then the check will be performed in a different way. For example:
Find the validator at the bottom of the site. Clicking opens a resource with documentation. Verification is carried out by comparing the names and addresses of servers. A similar option will work with portals registered through Curacao.
View information on the regulator's portal. This option works for websites registered in Malta. You will need to find the MGA License Register tab. It remains to click on it and check the company by URL or name.
The authenticity of any license can be checked on the websites of regulators. You only need to enter the permission number, and compare the information.
