PlayStation games are marked with special regional code, which is usually printed on the side of the game case. The code varies across geographical regions, such as Europe, America, Asia, etc. Blu-ray discs may be locked so that they only function on PS3 systems purchased in the same region, languages in the game may also be different for different regions.
The usual prefixes for PS3 software titles are as follows:
|BCES||NPEA||First party title, Europe|
|BLES||NPEB||Third party title, Europe|
|BCUS||NPUA||First party title, USA|
|BLUS||NPUB||Third party title, USA|
|BCJS||NPJA||First party title, Japan|
|BLJM||NPJB||Third party title, Japan|
|BCAS||NPHA||First party title, Asia|
|BLAS||NPHB||Third party title, Asia|
First letter – the storage format. Can be either “B” for Blu-Ray or “S” for DVD.
Second letter – first party game (Sony) or third party game (exclusive or not). Letter “C” for first party and letter “L” for third party.
Third letter is the region. “A” = Asia, “J” = Japan, “U” = United States and “E” = Europe.
Fourth letter: indicates the type of content. “D” = Demo, “S” = Game.
Games that have been purchased from PSN have other codes, see the table above.
