Plug adapters / Mexico
Do I need a plug adapter for Mexico?
No. Mexico uses type A and B sockets, the same shapes as the United States, so your plugs fit as they are. The supply is 127 V at 60 Hz, in the same range as the US.
What to pack for Mexico
Nothing extra for the sockets. At 127 V, phones, laptops and most small appliances from the US work as they do at home.

About type A and B sockets
Types A and B are the US and Canadian standard: two flat pins, with a round earth pin on type B. Being able to plug straight in is convenient, but it also hides any voltage difference, so check the number on the charger rather than the shape of the socket.
Voltage and frequency in Mexico: 127 V, 60 Hz
At 127 V, Mexico is within the range US devices are built for, so everything from a phone charger to a hair dryer works as it does at home. The frequency is 60 Hz, the same as the US, so there is nothing to think about on that side.
Same sockets elsewhere
Canada, Dominican Republic, Japan, Colombia, Jamaica and Costa Rica use at least one of the same socket types as Mexico, so one adapter covers a trip that includes them.
- Canada: type A/B, 120 V
- Dominican Republic: type A/B, 120 V
- Japan: type A/B, 100 V
- Colombia: type A/B, 110 V
- Jamaica: type A/B, 110 V
- Costa Rica: type A/B, 120 V

Frequently asked questions
What plug type does Mexico use?
Mexico uses type A and B sockets. US type A and B plugs fit without an adapter.
What voltage is Mexico?
Mexico supplies 127 V at 60 Hz. That is in the same range as the US 120 V, so US devices work as at home.
Do I need a voltage converter for Mexico?
No. The voltage in Mexico is in the US range, so no converter is needed for any device.
Will my phone charger work in Mexico?
Yes, provided it is marked 100–240 V, which almost every phone charger is. No adapter is needed because the sockets take US plugs.
