You will need an AUTH or EPP code from YorName:
www.yorname.com
1. Use your SimDif email and password to log in.
2. Select the name of your site and "Transfer to another registrar".
3. It takes a few minutes for the AUTH/EPP code to be generated.
4. Once the AUTH/EPP code is ready you may use it with your desired domain name registrar to transfer the domain.
Please note, to avoid problems during the transfer, a domain name can only be transferred 2 months after its last registration and 2 months before its expiration date.
