According to wikipedia it is zone 5. However, there are machines that are multi region(can read all region zones) called zone'0'. On the back of most machines the region codes are shown. If the machine is Region 5 only, then there are unlock codes for most macines that can be done by simple step processes when you first switch the machine on. So if you know the model number, look on the internet and seek out the unlock code. I hope this helps.
