French is the dominant language of Martinique, with a local dialect called "Creole patois" also spoken by some inhabitants. English may be used in tourist areas by hotel staff and guides.
Martinique is an overseas department of France and so it uses the same currency which is the Euro. Some hotels and restaurants will accept US dollars, although stores will not, and it is best to get Euros for cash transactions. The most favorable exchange rates are offered at banks, which are all French owned. There are also plenty of ATMsacross Martinique. Credit cards are widely accepted for larger purchases in hotels, restaurants and stores.
The time zone in Martinique is GMT-4.
Electricity in Martinique runs at 220-240 V/50 Hz variable. You may need a transformer if your electrical appliance differs (most North American electronics run at 110-120 volts). They use a two-pronged rounded European style plug so you will need an adapter for all other style plugs. Sometimes the sockets will accept a third grounding pin which is featured on some electrical plugs, although it is best to travel with a converter just in case.
The international calling code for Martinique is +596. Cell phone service is exceptionally good in populated areas, although you may not get much coverage in the more remote areas. There are several phone booths located in cities and towns. The island has an excellent internet network, and the majority of hotels will offer free Wi-Fi, which is also available in the country’s airport.
Duty Free goods can be purchased at Martinique Aimé Césaire International Airport. If you are traveling to the US, you are allowed to import one liter of alcohol and 200 cigarettes, 50 cigars or 4 lbs of tobacco.
