Interesting that they allow Swiss and UK residents to open an account. Why can't other pan-European banks do the same?
What country code does your IBAN start with?
MT
I have other accounts like Wise (that give you a Belgian, Turkish, and Hungarian IBAN) but the card has a UK registered number.
Revolut gives you a Polish IBAN if you have a zloty account with them, but again, the card has a UK registered number.
I had an account with Bankera - a Lithuanian bank - with an LT IBAN and a Lithuanian issued card, but they suddenly started charging €8.99 a month for the account, so I closed it - a surprisingly convoluted process.
I have previously had a German and an Italian bank account as well, both of whom closed my account due to Brexit, and both of whose cards were issued in their home countries.
My Bunq account has 3 (NL) IBANs (one current account, 2 savings accounts). Trading 212 gives you a Euro account with a DE IBAN, but the card is UK issued
