Help with registering FC?

[s p a c e c o w b o y]

My friend is trying to register my Heart Gold FC on his Soul Silver (my FC is 0390 0556 1667), and he keeps getting the message that it won't work. I've registered his, but he can't register mine. Why?

This doesn't belong here, this question is more for the game itself. You can ask in the 4th Gen Help Thread.
