HT2534 What is the security code? What if its invalid?

Question

What exactly is the security code in my billing information? I first Used the 3-digit number in the back side of my card. But a couple of days later a message appeared saying that this code is invalid. Now I can't download anything. What can I do? Can I just delete my Id and create a new one with the same email?

That won't work, it won't let you create a new Apple ID with an email associated with another Apple ID.
The message is a catch-all for any billing anomaly.
Make sure you are using a valid credit (not debit) card.
