⚠️ Why This Works
The 4242 card is Stripe’s official test card. Some sites leave test mode enabled in production (oops). Priyo’s checkout accepts it because their Stripe integration isn’t validating properly.
This could stop working anytime — they just need to flip one setting.
Never used a working card before? The BIN Masterclass explains the whole game.
i’m not afraid to use it but i don’t want someone faces trouble because of us. this transaction seems ligit and they said payment successful and in monthly pack this says 6$ paid. so i got confused.
A draw is a test mode and you won’t have anything to charge since it’s the admins’ fault that they forgot to turn off the test mode, which is a mistake on the part of the administration and not the users
This kind of card is used by testers when checking payment forms. You can insert them anywhere and it will not be considered a violation for you since these card numbers are issued by the payment servers themselves. but they will only work where the test mode is enabled, as is the case with this site.
