Your post isn't really clear.
What exactly do you mean by "Is the postel address now your registered addresses to the account?"?
And "Is it registered? Is the number registered to deliver addres"?
In case it helps at all there's no postal address associated with a My48 account.
The postal address is only used when sending a SIM out.
If that doesn't help then you'll need to explain/describe your question/issue more clearly and in more detail.
If you need to contact 48 support about this then see the links in my signature below.
