Sometimes when you want to call Cambodia, you don’t have the time to run down a mental laundry list of calling rules and codes.

So if you want to make calling Cambodia a more pleasurable, less stressful experience, grab a peek at our “How to Call Cambodia” guide below.

To call Cambodia from the U.S., just follow these dialing instructions:

  • First dial 011, the U.S. exit code.
  • Next dial 855, the Cambodia country code.

As a quick reminder, you may need to double-check a few important items before dialing internationally and calling Cambodia. Always make sure that:

International calling isn’t blocked on your cell phone.

Some cells are preset not to allow international calling, so you may need to undo this in settings.

The cell number being dialed is supposed to have an area code.

Many international numbers for cell phones won’t need an area code.

You’re using a “trunk” code properly.

A trunk code, or the zero you see occasionally listed as the starting digit of a cell phone number, is only used if you’re calling within a few nations. Chances are you won’t need it. So go ahead and drop the 0.
