Blu-ray Discs may be encoded with a region code, intended to restrict the area of the world in which they can be played, similar in principle to the DVD region codes, although the used geographical regions differ. Blu-ray Disc players sold in a certain region may only play discs encoded for that region. The purpose of this system is to allow motion picture studios to control the various aspects of a release (including content, date, and, in particular, price) according to the region. Discs may also be produced without region coding, so they can be played on all devices.
Region code Area
A Americas; East and Southeast Asia.
B Africa, Europe, Oceania; Middle East; French territories; Greenland.
C Central and South Asia; Mongolia, Russia, and People's Republic of China.
