If you’re using Moniker as a registrar, and go to transfer-out a domain, you should receive your EPP code via email within minutes after you set the domain to transfer out. If you haven’t, and you’ve checked your spam folder, you may want to take a look at your account settings.
Under Account Management > Email Preferences you’ll find the following:
Do not receive Order Confirmation Emails
This includes all new orders, domain/contact/nameserver management confirmations
If you have this checked, it will actually suppress sending you the transfer-out EPP codes. I learned this the hard way. I don’t know why suppressing EPP code emails should ever be available as an option but that’s just my opinion.
If you’re still not receiving your codes, and this checkbox is clear, you should contact Moniker support.
