Yepper - we discussed this change back in September, when I first noticed it:
I try to keep close tabs on SHC (“Seller Help Content”) articles - had to update several of them for the latest Editorial Team revisions earlier today - and I’ll be surprised if the language doesn’t change again over the next year or two.
Ah, @Dogtamer , you eternal optimist you…
I give it six months at best.
Well, to be fair, it must be admitted that one of the SHC pages related to this subject, “Registration Requirements by store” (link, Help Hub Rev. v.), has only seen a change in the article’s Title (previously, it was “Registration Requirements by Marketplace”), along with w/ relatively minor additions and/or revisions concerning other Global Marketplaces, since I first recorded it 24Feb2017.
In an example of just how all over the place Amazon is on this subject, these portions have not materially changed over the last seven years (italicized emphasis mine):
Oh, the joys of Silo Mismanglement…
I’m (kind of) hoping that I live long enough to be able to send some ‘Smellovision’ messages to posts for Amazon to get a whiff of their site results…
Hello
I already have my account back since yesterday. 
I didn’t get a new Visa credit card, because my bank said the same thing would happen.
I already had an open case with Amazon, where the answer was always the same, to wait 24-48 hours and I would get my account back.
What really helped me and resolved the problem was opening a case on the Amazon forums and whoever was following me in that case on the forum forwarded my problem and a case was opened internally, where my situation was analyzed correctly. In this new case, the same error was displayed: incorrect billing address or zip code, but I sent a proof that the address was OK. This person who analyzed the new case did things well, of course I had to wait, and yesterday I already had the account back, without any intervention on my side.
So from what I deduced, I live in Portugal, the validation mechanisms are different from those in America, I think that in Europe they don’t ask for validation of the billing address, in other words, Amazon tries to validate the cards and arrives here at the bank and gives error. That’s why the response from Amazon customer support was always the same.
For my situation, I follow another opened case, in amazon forum, that helped me to understand indeed which was the issue and to confirm that the issue wasn’t on my side:
https://sellercentral.amazon.com/seller-forums/discussions/t/9885c966-c48a-4d23-9f7b-c4a1cf840c9a?mons_redirect=stck_reroute
I appreciate all the help you gave me to resolve my problem, unfortunately, as the response to the first ticket opened on Amazon was not at all the best. What actually helped me was the second ticket that was opened by the right person, and forwarded internally.
Thank you SAS, I’ll continue reading what’s going on here.
Thanks
Lúcia
I have to wonder if there’s something in their agreement with card companies about accepting debit cards and the language is just to show that they do (wink, wink, nudge, nudge)
Hey, that’s wonderful news! We at SellersAskSellers never begrudge any Amazon Seller any help that comes from the official Amazon forum. So glad it was resolved for you 
And to keep the Amazon insanity going, at least some of the MODS will agree (off the record) that Debit Cards don’t work all the time —
I posted this for an OP that was having card problems –
"Be sure that you put a valid card in your BUYER side FIRST.
There are numerous posts noting that not having the same card there can cause issues.
ALSO, there are many posts indicating that despite Amazon saying they now accept Debit Cards for US accounts they do NOT always work."
Which was followed within minutes by this!
The entire post is very short but I’m sure the smiley from Amazon (anonymous of course) is from the MOD on the post!
So the moderator “help” is to open duplicate threads?
