最近，我妻子试图从她的 iPhone 在 iTunes 上买东西，她被要求验证账单信息(billing information)。
当她尝试输入信用卡(credit card)背面的安全码(security code)时，即使它完全正确，她也会不断收到“安全码无效”。(Security Code Invalid)奇怪的是，我可以从家里的MacBook和 iPhone 上毫无问题地购买东西。
无论如何，在对这个愚蠢的错误感到非常沮丧之后，我终于幸运地让它工作了。实际上，我无法弄清楚问题出在哪里，所以直到第二天我才做任何事情。当我们在 24 小时后尝试输入安全码(security code)时，不知何故它神奇地起作用了。
但是在网上做了一些研究(research online)之后，我发现这个错误可能由于各种疯狂的原因而发生，这真的很烦人，因为你没有得到关于它为什么不接受安全码(security code)的反馈。在本文中，我汇总了它可能会失败的一些原因以及如何尝试解决问题。
尝试重新输入贷记/借记信息
您可以做的第一件事是尝试重新输入所有credit/debit card info，看看是否有效。在 iTunes 中，转到Store，然后查看我的帐户( View My Account)。
接下来，单击帐户摘要页面上付款类型(Payment Type )旁边的编辑链接：(Edit)
在顶部，您将看到卡片列表和无选项。继续并单击None，然后单击Done。
保存后，继续并再次单击编辑(Edit)并再次输入您的信用卡信息(credit card info)。希望(Hopefully)它会接受卡信息(card info)，您将能够进行购买。
确保国家匹配
另一个导致很多人出现安全码问题(security code problem)的问题是，他们在 iTunes 中的居住国与他们的信用卡或借记卡所在国不同。
因此，最好确保您的credit/debit card账单地址(billing address)所在的国家/地区与您设置的地区所在的国家/地区(set region)相同。
锁定帐户
无论出于何种原因，有时您可能会尝试购买某些东西并且付款请求(payment request)被Apple拒绝。这可能由于不同的原因而发生，但基本上您的帐户会被锁定，直到余额全部付清。
不幸的是，这样做的唯一方法是使用 iTunes礼品卡(gift card)。所以基本上你必须购买一张 iTunes礼品卡(gift card)，然后将其应用到余额中。此时，您的帐户将被解锁，您将能够验证信用卡的(credit card)安全码(security code)。
仔细核对地址
发生这种情况的另一个原因是，如果您在 iTunes 中输入的地址与您与信用卡(credit card)关联的地址略有不同。例如，如果您住在5525 North Mounes St，而您在 iTunes 中有5525 N Mounes St，则两者不匹配，您将收到安全代码错误(security code error)。
因此，最好访问您的信用卡(credit card)或借记卡公司(company and check)的网站，查看地址的确切内容，然后确保您在 iTunes 中输入了该地址。
取消授权和授权计算机
您也可以尝试在您的 iTunes 帐户中选择“无”作为付款，然后取消对计算机的授权。
然后继续重新授权计算机并输入信用卡信息(credit card info)，希望您可以在没有错误的情况下输入它！
尝试不同的卡
通常问题出在 iTunes 上，但在极少数情况下，您的银行账户(bank account)中可能实际上没有足够的余额或信用卡上的信用额度不足以进行购买。如果没有其他方法起作用，请检查它作为最后的手段。
此外，如果您确实必须立即购买东西，您可以尝试使用不同的信用卡，它应该可以这样工作。(credit card)
希望(Hopefully)这些技巧中的一些能让您的卡在 iTunes 商店中再次正常工作！如果您有其他问题或(issue or something)此处未提及的内容，请发表评论，我会尽力提供帮助！享受！
Fix “Security Code Invalid” Error in iTunes
Recently, my wife was trying to buy something on iTunes from her iPhone and she was askеd to verify the billing information.
When she tried to enter the security code on the back of the credit card, she would just keep getting “Security Code Invalid” even though it was perfectly correct. The odd thing was that I could buy stuff without any problems from my MacBook at home and from my iPhone.
Anyway, after being very frustrated by this silly error, I finally got it to work by sheer luck. Actually, I could not figure out what the problem was so I just didn’t do anything until the next day. When we tried to enter the security code after 24 hours, somehow it magically worked.
But after doing some research online, I found that this error can happen for all kinds of crazy reasons and it’s really annoying because you get no feedback as to why it won’t accept the security code. In this article, I’ve compiled a few of the reasons why it might fail for you and how you can try to fix the problem.
Try Re-entering Credit/Debit Info
The first thing you can do is to try and re-enter all the credit/debit card info and see if that works. In iTunes, go to Store and then View My Account.
Next, click on the Edit link next to Payment Type on the Account Summary page:
At the top, you will see a list of cards and the option for None. Go ahead and click on None and then click on Done.
Once that has been saved, go ahead and click Edit again and type in your credit card info again. Hopefully, it will accept the card info and you’ll be able to make purchases.
Make Sure Country Matches
Another issue that caused the security code problem for a lot of people was the fact that their country of residence in iTunes was different from the country for their credit or debit card.
So it’s a good idea to make sure the country for the billing address of your credit/debit card is the same as the country for your set region.
Locked Out Account
For whatever reason, there are times when you may try to purchase something and the payment request is denied by Apple. This could happen for different reasons, but basically your account gets locked out until the balance is paid off in full.
Unfortunately, the only way to do that is to use an iTunes gift card. So basically you have to purchase an iTunes gift card and then apply it to the balance. At this point, you account will become unlocked and you will be able to verify the security code for your credit card.
Check Address Carefully
Another reason this can occur is if the address you have entered in iTunes is slightly different than the address you have associated with your credit card. For example, if you live at 5525 North Mounes St and you have 5525 N Mounes St in iTunes, the two won’t match and you’ll get the security code error.
So it’s best to go to the website of your credit card or debit card company and check to see exactly what the address is and then make sure that is what you have entered in iTunes.
Deauthorize and Authorize Computer
You can also try to select None as the payment in your iTunes account and then deauthorize the computer.
Then go ahead and reauthorize the computer and enter the credit card info and hopefully you will be allowed to enter it without the error!
Try a Different Card
Normally the problem is with iTunes, but there is the rare occasion where you might actually not have enough balance in your bank account or enough credit on your card to make the purchase. Check that as a last resort if nothing else is working.
Also, you can try a different credit card if you really have to purchase something immediately, it should work that way.
Hopefully some of these tips will get your card working again in the iTunes store! If you have a different issue or something not mentioned here, post a comment and I’ll try to help! Enjoy!
