Understanding the "Card Unavailable" Error

The "card is unavailable" error message has been reported by users during transactions on platforms such as Twitter, YouTube, and the Play Store. This wiki aims to provide an understanding of the issue and offer guidance on how to handle it effectively.

Upon investigation, it has been observed that this error is associated with new validation procedures implemented by payment processors. Specifically, these platforms are now cross-referencing the address attached to user accounts with the billing address associated with the payment card used for transactions.

One of the primary payment processors, Stripe, has recently updated its algorithm for location validation and card currency. This update aims to ensure compliance with regional pricing structures and prevent potential revenue loss due to currency discrepancies. Consequently, transactions originating from different countries may be subject to different pricing structures and validations.

For example, transactions made from Nigeria have a distinct pricing structure compared (and currency) to those from the United States. Therefore, when a payment card denominated in USD is used for transactions originating from Nigeria, it may trigger alerts within Stripe's algorithm, leading to the "card is unavailable" error message, or card declined response.

It's essential to recognize that this adjustment in validation algorithms is not unique to a single platform but rather a broader industry trend aimed at enhancing security and compliance measures. While these changes are ultimately beneficial in safeguarding financial transactions, they can inadvertently lead to inconveniences for users, as observed in this scenario.
