The main language in Chile is Spanish.
The local currency is Chilean pesos (CLP).
$100 bills must be 2003 or later, or they will not be accepted. For travellers cheques, there is often a $1/cheque fee, and the exchange rate is better for $100 cheques. It helps to bring smaller bills as change is not always available.
When calling Chile, you must dial the country code of 56.
Tri-band cell phones will work in most areas. You may also want to consider renting one
or getting a global cell phone.
Chile uses 220 volt current with a European plug (two round pins).
