You are my lifesaver tonight!!!! I've been fighting this dumb issue for over 4 hours now and was really to pull my hair out!!! Thank you VERY MUCH!!! At first, I almost didn't follow the link you provided because I KNEW my security code was valid and correct because, although the AppStore wouldn't accept my debit card info, a charge for balance was already showing up on my new bank account info! I finally seceded, clicked your link, and the info there wasn't regarding my security code being incorrect, as the link verbiage suggests, but about address info, the other responder mentions below. I'd already tried address fiddling, though, and to no avail, then I happen to glance at the address printer on my new checks, and voíla!!! The bank printed my zip code incorrectly! (Not to mention, they also sent me the wrong checks!!!). I just had to tell you how grateful I was for your link and assistance! Hope you're having a great summer!
