Currency in Peru

New Sol (PEN) = 100 centimos. New Sol notes are in denominations of PEN200, 100, 50, 20 and 10. Coins are in denominations of PEN5, 2 and 1, and 50, 20, 10 and 5 centimos.
Currency Exchange

Only a few bureaux de change in Lima will exchange currencies other than US Dollars. Outside Lima, it is virtually impossible. US Dollars can be exchanged everywhere and banks, hotels and shops also readily accept US Dollars (although torn or damaged notes are usually rejected). It is not recommended to exchange money from street vendors. ATMs are now generally regarded as one of the best ways to obtain money in Peru.
Credit / Debit Card Information

All major credit cards are accepted, but usage may be limited outside of Lima. Check with your credit or debit card company for details of merchant acceptability and other services which may be available.

Travellers Cheque Advice

Banks will exchange traveller’s cheques although it can be a slow process outside Lima. To avoid additional exchange rate charges, travellers are advised to take traveller’s cheques in US Dollars. The ability to use traveller’s cheques is also quite limited in some areas so you should check whether or not they will be excepted in the area your visiting prior to travel.
Currency Restrictions

There are no restrictions on the import and export of local currency. The import of foreign currency is unrestricted. The export of foreign currency is limited to the amount imported. Receipts of exchange of foreign currencies into S/. must be presented when exchanging back from S/. into foreign currency.
Banking Hours

Mon-Fri 0900-1800, Sat 0900-1300 (may vary during the summer).
