Check these three official lists
- Unsupported countries and regions for account access.
- Card issuance restrictions for whether a card can currently be issued.
- Card delivery restrictions for physical-card shipping.
Do not infer one result from another. Being able to register does not prove that a card can be issued or delivered, and having a card does not guarantee acceptance by every merchant.
Why country pages are not bulk-generated yet
Publishing many near-identical country pages before checking current official restrictions would create thin, error-prone content. Individual country pages will be added only when each of the three checks above has been recorded with a review date.
