If you wish to transfer your .RU domain away from Hostinger, that's what you need to do:
Make sure that your domain owner's contact email address is verified
Make sure you have access to the email account that you used when registering your domain
Be ready to provide photos of your ID or passport (if necessary)
Due to the nature of .RU domains, their EPP codes are not visible in hPanel. Therefore, once you take care of the points given above, reach out to our Customer Success team, and we'll help transfer your .RU domain to another provider.
