About the Verification Code
Will my Verification Code ever change?
Yes. Each time your bank issues you a new card, they will print a
different Verification Code on your card. For example, when your existing
card reaches it's expiration date, or if the magnetic strip stops working
so you request a replacement, you�ll get a new card with the same account
number but a different Verification Code. When that happens, be sure
to click Modify Card on the Buy Chips with Credit Card page to update
the Verification Code.
