If you have unlocked your domain but have not yet received the email with the EPP code, can you check the following:
That the email account you are checking is the same one you used when you bought the domain. That the email with the EPP code was not routed to your Spam folder.
If this does not solve your problem, please click on the email link below and let us know for which domain you're trying to get the code and we will investigate further.
Please note: If you're trying to transfer a .co.uk domain, the process for this is a bit different. Please refer to this: Transfer .co.uk domain to a new registrar.
