Is an iTunes card country-specific?
iTunes Gift Cards will only work in the same country they were bought in.


  iTunes Gift Cards are not available in Luxembourg, Portugal, or Greece. Gift recipient must have or open an iTunes Store account in the same country as purchaser to redeem gift. The iTunes Store is available only to persons age 13 or older in the U.S. and many other countries; see http://www.apple.com/support/itunes/ww for a list of countries. Requires iTunes 6.0 or later (7.0 or later for video), compatible hardware and software, and Internet access (fees may apply). Terms apply. See http://www.apple.com/itunes/store for more information.


Of course, if you buy a card for yourself, you’re both the purchaser and the recipient. So only buy iTunes Gift Cards in countries where you have an iTunes Store account.
