Each test card’s billing country is set to U.S. If you need to create test card payments using cards for other billing countries, use our international test cards.

We recommend using our test IDs when testing your integration and creating charges, instead of passing card information directly to the API. Using these test IDs in place of card numbers helps ensure your production integration is developed in a PCI compliant manner and is not going to handle card information directly. Each test ID is human-readable and represents card information that has been tokenized with our client-side libraries (e.g., Stripe Elements, Stripe.js).
