Games are published worldwide based on regions by publishers. Yes, the games are usually compatible with all PS4 from different regions but if you’re worried about region locked DLCs, Updates and Patches or supported language, you will need to look out for a certain region indicator before your purchase. This is especially important for your PSN codes as well. Because PSN codes are locked to the country that it is bought from – it must match the country of the PSN account. This also applies to DLCs and it must match the region of the PSN account and the region the game was bought from.
Certain games are released in different regions due to language and censorship which may not be appropriate if released in that region. Thus, games are released in batches dependent on regions. As seen in the pictures above, you might notice at the bottom back corner of your physical copy – a certain globe with a number on it. The number indicates which region the game is released.
To check if the game you bought is released for your region, here’s a list of region codes:
R0 – ALL R1 – Bermuda, Canada, United States and U.S. territories R2 – The Middle East, Western Europe, Central Europe, Egypt, French overseas territories, Greenland, Japan, Lesotho, South Africa and Swaziland R3 – Southeast Asia, Hong Kong, Macau, South Korea and Taiwan R4 – Australasia, Central America, the Caribbean, Mexico, Oceania, South America R5 – The rest of Africa, Former Soviet Union, the Indian subcontinent, Mongolia, North Korea R6 – Mainland China
Below are some examples of region indicator at the back cover of the games:
