Usually a currency mismatch between the card and your Netflix bill. A card in the right currency fixes it; mis-matched value cannot be converted.
Redeem guide
One web page, two minutes — and two things to check first: your billing currency and who bills you.

Quick answer
Go to netflix.com/redeem in a web browser, sign in (or start a new account), enter the gift code and select Redeem. The value becomes Netflix balance that pays your plan automatically each month. The card's currency must match your Netflix billing currency, and accounts billed through a partner must switch to Netflix billing first.

A Netflix gift card works when its currency matches the currency of your Netflix bill — a euro card on a euro account, a US dollar card on a US dollar account. And if your Netflix is billed by a partner (an app store, your phone or TV provider), cancel billing with that partner first, then redeem at netflix.com/redeem once the last partner billing period has ended.
