Sockets in the Northern Mariana Islands
The plug types you’ll find in the Northern Mariana Islands are Type A and B plugs and sockets.
Type A
Type A sockets have two flat parallel pins and no grounding. Unlike Type G, they don’t include an earth pin, which makes them less secure.

Recommended Travel Adaptor for the Northern Mariana Islands
Many adaptors didn’t pass our tests, but this one did. We looked at safety, durability and value for money. That’s why we confidently recommend it.
Forgotten your adaptor and already abroad? Don’t worry — airports and local shops usually stock them. That said, packing your own saves you from high prices and poor quality.
The Northern Mariana Islands are often combined with trips to Guam and Japan. It’s worth checking the plug info for those too — they don’t all use the same system.
Do You Need a Voltage Converter?
Bear in mind the mains in the Northern Mariana Islands doesn’t always match our 230 V back home, so you’ll likely need a voltage converter.
Don’t forget to check the voltage label on your device before use overseas. If it’s stamped ‘100–240 V, 50/60 Hz’, it’ll work in most places without a converter.
