Blu-ray discs, like DVD, contain region coding, but many-many titles are region free unlike what we experienced with DVD. Also, Blu-ray discs use only three regions instead of DVD's original eight. The three regions are:
Region A: North, Central, South America, Japan, Korea, and Southeast Asia.
Region B: Europe (EU), Africa, Middle East, Australia, and New Zealand.
Region C: Russia, India, China, and the rest of the world.
Some Blu-rays will show as region ABC, which is essentially a region free disc.
