The Auth-Info Code is a unique code generated on a per-domain basis and is used for authorization or confirmation of a transfer request. Some registrars offer facilities for you to generate and manage your own Auth Info code. In other cases, you will need to contact the registrar directly to obtain it. The registrar must provide you with the Auth-Info code within 5 calendar days of your request.
The Auth-Info code is applicable to transfers of all gTLD names, with the exception of .gov, .edu, .mil, .museum, and .int names.
