Someone is trying to transfer a domain name to my Godaddy account, I've provided him with my associated email address with Godaddy, and my ID, however, it shows him that the ID is invalid..
What would be the cause of this issue?
There are two way to move a domain.
First is an account change. If it is coming from another GoDaddy account, then using the account change feature should work with the account# and email address on file for the account.
The second way is an actual transfer. This is when the domain is coming from a registrar other than GoDaddy. The process is very different. You would have to purchase the transfer and then send an authorization code.
In both cases the domain has to be unlocked.
I hope that helps.
