The codes on this page are Steam wallet codes in euros, meant for accounts with a euro wallet — usually Steam accounts opened in eurozone countries. They also work as a gift for someone close to you who lives in Europe: you send the code and they redeem it on their own account. The currency of an account can be checked on the account details page in Steam; if it is a gift, ask that person which currency they have.
After payment the code appears under “Orders” in your account. A delivered code cannot be returned or exchanged. If a code does not work, contact support within 48 hours of receiving it, with a screenshot of the error.
