To register a domain, first check the availability of the domain on the website dig.ua. If the domain does not belong to anyone, then the search will not return a result, otherwise you will see data about who registered the specified domain.
A domain available for registration can be registered on the website of one of the Accredited registrars. Choose the registrar you feel most comfortable working with, go to their website and apply for the domain you want.
Once you have registered a domain with an Accredited Registrar, it will not start working until you have confirmed the domain registration. A confirmation code is sent by SMSto your mobile phone, after confirmation, the previously registered domain is delegated. Otherwise, if the domain is not verified, it will be deleted after 5 days from the date of registration.
