Blu-Ray discs contain Regional Codes which can be used to prevent the playback of certain discs depending upon the geographical area it is played in. The various studios and home video companies lobbied to make sure this coding system was a required part of the current Blu-Ray standards, because they wish to control how their Blu-Ray titles are exported to other countries. In most instances, discs manufactured in one region will usually only play on players that were manufactured in that same region - this means that discs bought or imported from Japan or Hong Kong will not play on U.S. players, and vice versa. However, the regional coding system is entirely optional, and discs without Regional Codes will play on any players in any countries. All region Blu-Ray players will play any Blu-Ray regardless of their regions. Please be sure your Blu-Ray player plays the encoded Blu-Ray when ordering. Information below is for reference only and we do not guaranteed its accuracy. Please see your player's manual for details about your region coding.
