Student discounts are common in Argentina, but usually only if one has appropriate ID. STA Travel (tel. 800/781-4040 in the U.S., 0871/230-0040 in the U.K., or 134-782 in Australia; www.statravel.com) specializes in affordable travel for student and young travelers, and issues the International Student Identity Card (ISIC), widely recognized as proof that you are a student. As well as offering discounts on a range of travel, tours, and attractions, it comes with a 24-hour emergency help line and a global voice/fax/e-mail system with discounted international telephone calls. Available to any full-time student older than 12, it costs $21. If you're a student planning to stay long term or study in Argentina, consider also looking at the U.S. State Department's website for student travelers, http://studentsabroad.state.gov.
