Chamorro and Carolinian stand alongside English as the official Northern Mariana Islands languages, but some people in the tourism industry also speak Korean or Japanese.
The US dollar is the official and only widely accepted currency on the Northern Mariana Islands. Foreign currency exchanges and international banks are commonplace in Saipan, but even the smaller islands of Rota and Tinian have their own bank branches with ATMs. Travelers’ checks and major credit cards are commonly accepted at most hotels, restaurants, shops, and other tourism-related industries.
The Northern Mariana Islands share the same Chamorro Time Zone as Guam and the Australian state of Queensland, 10 hours ahead of GMT (GMT +10).
The Northern Marianas Islands use the same 110-120V electricity settings as the United States and Canada. Type B and A plug sockets are both commonly used. However, all visitors should still bring plug adaptors and transformers in order to be sure they can still use their electrical appliances.
The Northern Marianas Islands dialing code is +670, followed by a seven-digit local telephone number. DOCOMO Pacific Guam is the main cell phone provider.

The two main Northern Mariana Islands duty-free shops are located at DFS Galleria Saipan and Saipan International Airport. The DFS Galleria Saipan shop is the larger of the two establishments.

Narcotics, unlicensed firearms, and some foods cannot be imported into the Northern Mariana Islands.
