If you would like to transfer a domain from one registrar company to another, you’ll have to go through a few safety procedures. One of them is obtaining a unique EPP code from the present domain registrar – provided that you are the registrant, since the code is emailed to the owner's mailbox and no one else can get it. You need to provide this code to the new registrar, otherwise they will not be able to start the transfer procedure. The EPP authorization codes are case-sensitive and may contain numbers or special symbols such as dots or commas, which can be easily misentered, so make sure you copy and paste the right code. As an additional safety measure, the transfer code for a domain may be altered on a regular basis. Certain domain name registrars call this code an Auth key, a domain password or a domain secret as well.
