How to get my domain Authorization code?

I registereda domain through discountasp.net web hosting package two years ago.

Now I want to know how to get my domain's Authorization code and how to unlock my domain in order to transfer my domain to other places.

If you know how to do it, please help me, thank you so much!

 

If your account is still active you will have to contact the billing department for the code. If your account is canceled, domain management information was included in your cancellation acknowledgement email.

 

Thank you
