Help for British nationals in South America:


It is best to travel to South America with a supply of US dollars rather than trying to obtaining any Argentine pesos here. Dollars can always be changed for local currency and are more widely recognised than euros or pounds.


It is always a good idea to visit an airport ATM when you land, before leaving the airport.  Some ATMs may give you the choice of taking out either local currency or US dollars. You should always take sensible precautions when using bank ATMs.


It is generally easy enough to travel throughout Argentina using bank ATMs but these are not always available in remote locations in Patagonia, Ibera or the north-west. We always recommend you keep a supply of US dollars handy and make sure that notes are clean and undamaged. Torn or damaged notes (e.g. from a staple or written on) will not be accepted.


We also suggest that you have a supply of single 1 dollar notes as these are useful for tips for airport and station porters and for hotel staff.


Credit cards are widely accepted in hotels and the better restaurants and shops but may not be accepted in small shops, cafes, bars and restaurants, nor in local markets.


In general terms, MasterCard is more widespread than Visa. It may be a good idea to take both if you have them. Usage of American Express is rare. If you are a regular traveller to countries where the currency is the US dollar (e.g. Ecuador, Panama, the United States)  you may like to consider obtaining a currency card. Caxton FX, Foreignex and FairFX are amongst suppliers. Charges and fees vary.
