Zone Codes are a "Digital Rights Management" technique designed to allow film distributors to control aspects of a release, including content, date, and price, according to the physical region or country it is going to. This is achieved by way of "Locked" or "Code-Locked" Blu-Ray players, which will play back only discs encoded to that specific player's sale zone. This means that every Blu-Ray Player you see in your local BestBuy or similar Electronics Store will be a "Locked" Player; one that will only play discs that are made for the USA zone (in other words, discs labeled "Zone A"). However, we carry "Code-Free" DVD players, which ignore zone coding, allowing you play any disc from any country, no matter which zone number it says on the disc. These players are the most popular types of players today because people are starting to watch more foreign films from other countries, and these players allow them to do that.
