Several international Amazon accounts use same card

[Sammuel]

Will Amazon link accounts in different countries (US / UK / JP) if all of them were opened from different emails but use same debit card and company name?

The platforms appear to be separate, but some have said they got suspended on multiple markets when having an issue with 1.

I guess it depends on the kinds of problems you have on 1 market whether others would be affected

If you're able to keep your info separate, go with the safer least risky option just in case
