In order to transfer a .IS domain to a different registrar we would need to update the domain's registrant contact handles.
If you are transferring the domain directly to the ISNIC registry, we need to update the details with your own contact handle.
If you are transferring the domain to a new registrar, we need to update the details with the ISNIC handle of that registrar.
Please login to your iwantmyname account and forward the relevant handle ID to us via our support form. This will provide the required security authentication, and then we can proceed.
