CSC is the abbreviated form of “Consumer Software Customization” or “Country Specific Code“. CSC is an essential component of Samsung firmware binaries and it contains customized settings, system configurations, localizations and geo-specific things such as the system language, APN settings, and carrier-branding. That’s is say, Samsung may release the same model of a phone in a country or region with different CSCs. For example, if you live in the United States and own a Samsung Galaxy phone, the CSC or product code of your device may be one of the following depending on the fact whether it is unlocked, open or carrier-branded. 

ACG – Nextech/C Spire 
ATT – AT&T 
CCT – Comcast 
LRA – Bluegrass Cellular 
SPR – Sprint (CDMA) 
TFN – Tracfone 
TMB – T-Mobile 
USC – US Cellular 
VMU – Virgin Mobile USA 
VZW – Verizon 
XAA – USA (unbranded/unlocked/default) 
XAS – USA (unbranded/unlocked) 

Samsung servers check on the CSC code of your Samsung device and match it with the geolocation where it’s being used. If both these things match before sending OTA updates to your device. Suppose the CSC code of your Samsung device is INS (India) and you take it to the United Kingdom or Germany and use it there, you may not receive the official software updates from Samsung. Again, the CSC of a Samsung Galaxy phone firmware contains the code-name of the country/region for which it is built. You can change it to tell Samsung servers that your phone is actually from a different country or region to receive official updates. Similarly, if you flash the firmware meant for some other country on your device, you’ll not get any future updates unless you install the proper firmware. For example, I have flashed the firmware with OXM CSC on my Indian Galaxy S9+ just to try Android Pie because it’s not yet available in India. Since OXM is Multi-CSC or Omni CSC, it offers a total of 86 different CSCs to choose from The idea of changing the CSC of your phone drops in here. Thus you can install firmware from a different region and change the CSC of your phone with a little trick and everything goes fine

Thanks, this is useful information as I am trying to understand what the CSC influences and what it doesn't. Do you know if the bands are affected by a firmware change? Conversely, for example in Japan, the camera is supposed to have a shutter sound - do you know if, on a device taken to Japan,  changing CSC to a Japanese CSC brings with it the shutter sound? Most curious about things like this... :)
