What is the code under the driver's door on my 09 Ford Escape?

There are 5 rubber buttons, each with two numbers (0/1, 2/3, 4/5, 6/7, 8/9) under the driver's door to unlock the car.

Where can I find the code?

There's usually a sticker under the drivers side dash. When I had a Freestyle i was able to use a mirror to see it hidden on the back side of a black plastic box.
