CSC CODE MEANING
For CSC, you can notice a different scheme: between the phone model and the release code, there is no 2 letters but 3, in my case OXA, it is simply a code explaining from which country and which operator this phone is. OXA is supposed to be O2 UK and for SFR France (code should be then SFR).

Conclusion, this is not harmful to your phone having a different CSC code than the one you are supposed to use. But if you want to properly change it anyway, you can do it using the code *#272* IMEI# (if you don't have it, your phone IMEI can be obtained using the code *#06#), the CSC menu is displayed and shows your current CSC and a list to change your phone CSC.

Samsung official letter code section and pray to have in in you CSC list
If it isn't, then choose the X?? version (for France it is XEF), it is for retail code (i.e. not operator branded). But be careful, if you apply a new CSC, it is phone factory reset (all your data and settings are lost).
