Happy 4/24/24! In the last 14 years, developers have used Stripe's 4242 test card number nearly 12 *billion* times. While 4/24 has passed, you can still use the 4242 test card with a future expiry date: https://lnkd.in/gcnd5NcS

And incredibly, the test card number 4242 became much easier to remember than the Mastercard 5555.

We've tried to simulate so much payment fraud on that poor 4242 card, but it always has the answer for everything.

A good bunch of those was me. Seeing 42424 being used 12 billion on my birthday feels like a secret birthday nod (24th as well) from the universe. I appreciate that.

I probably used it at least 4242 times myself. Good that you keep it so I don't have to update my shortcuts

I was so hoping as I started reading that it had been used 4,242,424,242,424,242 times, but we've got a way to go yet...

I’ve used this card half a billion times for testing the Wing Delivery app alone
