Money and Tipping
Currency: The UAE Dirham is the currency used in Abu Dhabi.
Tipping: Tipping is not expected but is commonly practiced in the Emirates. Gratuities to hotel and restaurant staff are at your discretion. Many fine dining and high-end restaurants may add a service charge (usually around 10%) and a tourism levy of 6% to your bill.
Electricity and Voltage
In Abu Dhabi and all places within the United Arab Emirates the associated plug type is G, which is the plug that has three rectangular pins in a triangular pattern. Abu Dhabi operates on a 230V supply voltage and 50Hz.
Visit your country’s government website for information about and recommendations for traveling to Abu Dhabi. When traveling outside your home country, it is recommended that you notify your embassy’s or consulates’ office of your travel dates and destination.
