Use the billing address shown on the card's own page, not your home address. The card is issued in the United States and carries a US address that the issuing bank assigns to it. Merchants and ad platforms check what you type against that address, and a mismatch is declined — which reads to you as "the card does not work" even though nothing is wrong with it. There is a copy control beside the address for exactly this reason. This is the most common reason a good card is refused on Google or Meta.
