Some websites and apps ask for a billing address when you pay with your card.
Your billing address is the address you entered during verification (Proof of Address). There is no other billing address for your Simple card.
How to fill it in
Enter exactly the same street, city, postal code and country as in your verification, spelled the same way.
If you don't remember it, use the address on the proof-of-address document you uploaded (utility bill, bank statement, etc.).
Good to know
The billing address is not shown in the app, and our support team can't see your personal data, so we can't tell you the address.
The billing address can't be changed, including by redoing verification.
If a merchant still rejects the correct address, the check is on the merchant's side. Try paying on another website or with another merchant.
