help with disc region

[danielk]

i just bought a game from an internet shop and i don't know which region this disc belong.
i know that the ps4 is region free but i want to buy a dlc to this game and from what i heard the dlc have to be from the same region store.
does anyone know a method to find out from which region the disc is?
