We want to inform you about an essential update regarding the transfer process for .ES domains. Starting November 19th, 2024, the .ES domain registry (Red.es) will adopt the standard "authcode" method for domain name transfers. This change is designed to boost the security of domain transfers, but will require some updates to your systems to accommodate the new process.
We have also sent an email about this important change, which you can view here with all the information.
