DVD region codes are a DRM technique designed to allow motion picture studios to control aspects of a release, including content, release date, and price, according to the region. DVD video discs may be encoded with a region code restricting the area of the world in which they can be played.
The DVD Copy Control Association in California, USA, requires that DVD player manufacturers incorporate the Regional Playback Control (RPC) system – according to the Australian government's anti-monopoly watchdog, the ACCC.
| Informal term meaning "worldwide". Region 0 is not an official setting; discs that bear the region 0 symbol either have no flag set or have region 1–6 flags set.

DVDs sold in the Baltic States use both region 2 and 5 codes. DVDs sold in Japan use the region 2 code, while Macau and Taiwan use the region 3 code. Hong Kong has historically used Region 3 and has added region 6 since the reunification, now using both.
Region 0 (playable in all regions except 7 and 8) is widely used by China and the Philippines. DVDs in Hispanophone Latin America uses both the region 1 and region 4 codes. Most DVDs in India combine the region 2, region 4, and region 5 codes; Indian Disney discs contain only the region 3 code.
European region 2 DVDs may be sub-coded "D1" to "D4". "D1" are United Kingdom–only releases; "D2" and "D3" are not sold in the UK and Ireland; "D4" are distributed throughout Europe.
Any combination of regions can be applied to a single disc. For example, a DVD designated Region 2/4 is suitable for playback in Western Europe, Oceania, and any other Region 2 or Region 4 area. So-called "Region 0" and "ALL" discs are meant to be playable worldwide.
The term "Region 0" also describes the DVD players designed or modified to incorporate Regions 1–6, thereby providing compatibility with most discs, regardless of region. This apparent solution was popular in the early days of the DVD format, but studios quickly responded by adjusting discs to refuse to play in such machines. This system is known as "Regional Coding Enhancement". this was a retroactive attempt to prevent the playing of one region's discs in another region, even if the disc was played in a region free player. The scheme was deployed on only a handful of discs. The disc contained the main program material region coded as region 1. But it also contained a short video loop of a map of the world showing the regions, which was coded as region 2, 3, 4, 5, and 6. The intention was that when the disc was played in a non-region 1 player, the player would default to playing the material for its native region. This played the aforementioned video loop of a map, which was impossible to escape from, as the user controls were disabled.
However, it is easy to work around the scheme. A region-free player tries to play a disc using the last region that worked with the previously inserted disc. If it cannot play the disc, then it tries another region until one is found that works. RCE could thus be defeated by briefly playing a "normal" region 1 disc, and then inserting the RCE protected region 1 disc, which would now play. RCE caused a few problems with genuine region 1 players.
, many "multi-region" DVD players defeat regional lockout and RCE by automatically identifying and matching a disc's region code and/or allowing the user to manually select a particular region.
Most DVD PC software and hardware can play both NTSC and PAL video and both audio standards.
Implementations of region codes
Standalone DVD players
Usually a configuration flag is set in each player's
firmware at the factory. This flag holds the region number that the machine is allowed to play. Region-free players are DVD players shipped without the ability to enforce regional lockout (usually by means of a chip that ignores any region coding), or without this flag set.
However, if the player is not region-free, it can often be unlocked with an unlock code entered via the remote control. This code simply allows the user to change the factory-set configuration flag to another region, or to the special region "0". Once unlocked this way, the DVD player allows the owner to watch DVDs from any region. Many websites exist on the Internet offering these codes, often known informally as hacks. Many websites provide instructions for different models of standalone DVD players, to hack, and their factory codes.
Computer DVD drives
Older DVD drives use
RPC-1 ("Regional Playback Control") firmware, which means the drive allows DVDs from any region to play. Newer drives use
RPC-2 firmware, which enforces the DVD region coding at the hardware level. These drives can often be reflashed or hacked with RPC-1 firmware, effectively making the drive region-free. However, this usually voids the warranty. Another criticism is that region-coding allows for local censorship. For example, the Region 1 DVD of
Stanley Kubrick’s
Eyes Wide Shut contains the digital manipulations necessary for the film to secure an MPAA R-rating, whereas these manipulations are not evident in non-Region 1 discs.
