I resolved this problem for myself today, though it may not help everyone. I called my bank and the problem was NOT an invalid security code though that is what was stated on iTunes. My bank has put a hold on all credit card transactions in California and New York because of massive fraud in those two states. The bank was therefore refusing my credit card transactions on iTunes, I assume because those transactions are handled in California. The solution by my bank was to issue me a gift card, deducted from my account, which they agreed to pay all fees for. I went to iTunes and changed my billing information to the gift card and it worked like a charm for me. I hope this helps some of you others with the problem.

Awful. I spend all this money on an iPad and it won't let me use it. Was on the phone with customer service and even they couldn't fix it, despite a bunch of tries at different things. All to no avail. I'm waiting on them to reset my account. If that doesn't work, i'm in a heap of trouble since this is all being done for work. Fingers crossed.

I have the same issue, only I have an Ipod touch 3rd generation. I've had it for about a month and it's been working but now I see the security code Invalid when I know it's right. ALthough my card expires march of this year so it might have something to do with that. Also, I've noticed, most people that say they are having issues use bigger banks where I use a local bank. Anyone have any ideas? I've tried almost every solution mentioned only I refuse to create another account, I don't want to lose my paid apps. I know people say it doesn't work, but I intend to contact Apple and my bank to see if anything is wrong there. If I figure anything out I will be sure to post.

I've just started to have this problem yesterday on my iPad . Ive been able to buy apps from the app store on the iPad itself but just starting yesterday it's been asking me to update my billing information and every time it tells me th security code is invalid. Card expires 2012.

I am having the exact same problem. People are saying to simply use another card but the issue is that I don't HAVE another card to use, and I would like to continue to use the one that I've BEEN using. Apple seriously needs to fix this. Now people are offering to give them money and they're making it difficult to take it? Not only that but I've spent money on the Line 2 app that is payed for, for the next 6 months and how it can't make its update? Thank you apple.

Okay here's what you do:
1) enter in new card info (another credit/debit card) either in your name or a friend's
2) hit "done" and logout of account when the new card goes thru
3) log back in to your account
4) choose "view account/view sign in"
5) now enter in the info of the card that you want on your account

This worked for me

Everyone is having this issue and it came with the last update. Apparently this is a recurring thing; this same glitch has been popping up after a lot of the past updates as far as I can tell.

I cannot believe this many people are having the SAME issue and Apple has yet to do anything. I also cannot believe I shelled out as much money as I did for my iPad and now I cannot use one of it's main functions....buying Apps & Music! ...or downloading free ones for that matter! What nonsense. It is truly disgraceful that nothing is being done about this problem....and with it going on for how long?? Seriously, I am becoming extremely disgruntled with Apple products and Apple service in general.

Total BS if you ask me...

Having issues with my iPhone 4 (Verizon) uploading pix to Facebook, so I was told to dump the app and re-download it. As I was trying to re-download Facebook it said I needed to reverify my acct. info, which included my security code. Well, it is saying my security code is wrong..... Seems like a very common issue based on all the chatter here, not to mention it has been going on for some time. What gives??? I know my CC info is correct.

I am an Apple customer and believe in the quality they produce, but this is bunk and making me reconisder my droid and even PCs. I shouldn't have to enter CC info for free games an apps, etc.

Please fix this NOW!!!!

I had this problem for a couple of days only, but I don´t want it becoming weeks, so please help someone fix this!
