Q: There was a problem with my billing information

The usual reason that credit cards fail to validate is that there is some minor discrepancy between the details that you enter and those that your financial institution have on file for you, for example Rd. vs Road. Check your statement and make sure the details match.

This probably happened because gift cards cannot be linked to a specific owner/billing address. Have you ever made a purchase with that Apple ID? You will probably need to use one of the approved payment methods for your billing. See this support document for the approved payment types. Payment methods you can use in the iTunes Store, App Store, and iBooks Store - Apple Support    If that does not help, then contact iTunes support for help. http://www.apple.com/emea/support/itunes/contact.html

Good catch!

Thanks.

There are normally some hoops you can jump through as you create your iTunes account that workaround the need for a card, otherwise once the account is set up iTunes may still expect you to provide one, which you can subsequently remove. If you don't have or want to use a credit card at this time you can try this method...

1. Enable the menu bar if needed with Ctrl+B (Applies to Windows only)
2. Sign out of the iTunes Store from the Store item on the menu bar
3. Go to iTunes Store home page
4. Go to Quick Links > Redeem
5. Sign in with your Apple ID
6. Go through the screens, accepting the EULA, etc.  You should arrive at a Review Payment screen where one of the options is None - select this and continue. You shouldn't actually need to redeem a new voucher/card.

It is worth noting that one of the functions of the registration is to prove you have a valid billing address in the region whose store you are trying to use. Pre-paid cards are not sufficient for that task.
