IalaThat isn't correct, I use amazon accounts in three different countries, and all share the same address book and credit card information. I also know that I need to verify credit card information only once changed, and theses changes are valid in all three shops at once.Amazon is run as different companies in each country, so not that surprising.
Even with identical account names and emails, the accounts are strictly separate.
That must have changed then. Last time I got a new credit card I had to update my information separately in the US, UK, and Germany.
Same with when I moved a few years ago and thus my address changed.
