Of course I can not Register my credit card, too. can I?
Now I add my country zip code, and it did not apply any new status about state.
Actually, In my country , we do not have “state” . just AABBCC prefecture and city.
So I thought I would apply, another “state” in the option,
but If something wrong, I do not want to take on responsibility,
so I stopped.
Though I am not so surprised if DAZ do not concern about so many other country people
when renewal their shopping site.
(though the sysytem can understand my country, and they can sell many items to me, huhu)
So I just use pay-pal.
it may be lucky for me. I do not want to record my credit card infromation on daz account.
I can not believe “DAZ technology at least about keeping shoping site safety”. 
====================================
I must say sorry about this , It was my mistake .
card register system can run about my country.
I thought I should input the state name, but,
when I apply my zip-code again, green check mark turned out.
(chohole said that? )
so please call me a careless complainer!
I do not mind.
I will change my HN “CC kita”
