Guinea-Bissau's customs authorities may enforce strict regulations concerning the temporary import or export of items such as firearms, antiquities, medications, and business equipment.
Currency: International banking and finance is problematic due to a limited formal banking sector. ATMs are not available, credit cards are not accepted, currency exchange exists at banks and hotels and is available on the street. Wire transfer possibilities, while limited, are available and repatriation of funds is problematic. Purchases of goods and services are possible only in cash and in the local currency, the Franc of the West African Economic and Monetary Zone (CFA). It is recommended that travelers secure more than adequate sums of CFA before arriving in Guinea-Bissau.
Consular Notification: As there is currently no U.S. Embassy in Guinea-Bissau, and no consular notification agreement between Guinea-Bissau and the United States, U.S. consular officials may not be properly notified when a U.S. citizen is arrested or detained in Guinea-Bissau. U.S. citizens are encouraged to carry a notarized copy of their U.S. passports with them at all times to have proof of identity and U.S. citizenship is readily available if questioned by local officials.
