To transfer a TLD domain name away from 123-reg, you will need to follow these instructions:
Your Authorisation/EPP code will be sent to the admin contact of the domain name. The admin contact must be a valid email address which you have access to in order to receive the authorisation code.
If the admin email address is not correct and is in need of a update please follow the instructions in this FAQ.
In the Domain names section, select the relevant domain name in the drop-down list and click on the Manage button.
Click on Manage Domain Locking to unlock the domain name.
Return to the previous menu.
Click on Request Authorisation Code
Once you have received the authorisation code, you will need to provide this to the new registrar that you wish to transfer your domain to. They will be able to advise you on their steps to transfer the domain name to them
The transfer process for TLD domains can take up to 7 days to complete once the transfer has been approved.
Please note: Top Level Domains names that are newer than 60 days or within 7 from the expiry date can not be transferred in or out of 123-reg.co.uk.
A .mx domain transfer request cannot be requested during the last 10 days of its renewal grace period.
