Q: Security code is invalid. iTunes for iTouch.

I see everyone here has the same problem, but what has been dont to fix it because mine still isn't working.

I had the same issue when my debit card expired.  Over and over again I entered my security code and was rejected.  But I just fixed the problem.  I selected "none" as my billing option and saved.  Then I went back in and changed it to MasterCard and entered my info.  It didn't take the first time, but I did it a second time and it saved and I was able to make my purchase.  Hope this helps.

I've been having a similar issue to, but the reason was because I had a pending purchase that was more than the amount I had on my ATM card.  Once I added enough funds for it to cover, it worked fine.  Hope that helps.

I had the same issue, I never get charged the day I make the purchase, it's like Apple knows when I have no money and THEN they charge me lol. Anywho, now I'm getting the stupid "Please enter valid security code" message even though I've entered it a million times, and it is indeed "valid". I downloaded the most recent update, I've signed in and out and nothing works. Now my AppleTV won't let me watch anything. And to top it all off my iPhone crashed this morning. I'm a loyal Appleholic, please please please say there's a fix for this bug!

Apple id automatically deducts from my debit card and in the account i get a notification that .

But have not made any purchase why is it so ????

So I've read through this entire thread, and despite the suggestions here I am still unable to update my billing information, with the constant "Invalid Security Code" crap on my perfectly good credit card. Please help!

Also, where are people seeing this PayPal option? it's not coming up in iTunes for me...

Am havin the same problem what can i do to fix it.

The same thing has been happening to me, if you have a PayPal account you  can bypass it. And my account is linked to my card anyway so it still comes from the same place

Only fix i can find but its working great for me, i can update download and purchase

The PayPal option is on iTunes on the computer, under your account and then payment information

As odd as it sounds, this problem has nothing to do with your credit card on file. I first encountered it when an old iTouch's battery was dead for a few days. When I recharged it, this error began to come up. All I had to do was reset the date and time on the device and everything began to work properly.

I just had this same problem on my iPhone, though my iPhone had never died. Anyway, when entering the credit card info didn't work (as is well documented here), I went to Settings>General>Date and Time. I turned off "set automatically," then set the time myself. Then I went back to the App store, entered my password, and everything worked as it's supposed to.

I have had this problem for about good 2 weeks.

SOOOO ANNOYING! My iPhone 4 did well & accepted my credit card.

Now that i have signed in with my MacBook Pro, the

problem yet again comes back! Now i cant purchase music

nor update any of my APPS!

APPLE YOU NEED TO FIX THIS!

hello mate am how did you get your iphone 4 to accept your credit card because am having difficulties trying to update my financial status on itunes and my card is a mastercard it keeps telling me IN VALID SECURITY CODE which annoying considering my bank says everything is fine...pls reply

The only answer I have is what I posted on Nov. 6. That solved the problem for me.

i had this problem...did you re-enter your expiration date? i thought mine was in there--there were little dots so i thought it was hidden...but it wasnt there. try double checking that

Very Helpfull Thank u.

I'm going to call to Bank service then they unblock for me.
