Normally domains have a lock on them so you need to contact your current registrar to ask them for the EPP code, and make sure the domain is not locked. We will then intiate transfer and you will need to approve the transfer when you receive an email from the registrar.
.NL domains do not have an EPP code, so you will only need to contact your current registrar to tell them that you will be transferring the domain. Once they confirm that this is ok from their side, we will initiate the transfer.
