CSC on Samsung

CSC or Consumer Software Customization/Country Specific Code is a very essential part of firmware components. It also contains various custom settings, system configurations, and geo-specific things.

Thus, it means that the same model of a phone can get a release by Samsung with different CSC. For example, if you live in the United States and have a Samsung Galaxy phone; then your device’s CSC or product code may be one of the following; depending on whether it’s unlocked, open, or carrier-branded.

ACG – Nextech/C Spire


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/standard)

XAS – USA (unbranded/unlocked)

Samsung servers will check the CSC code of your Samsung device and match it with the location where it is used. If these two things match, OTA updates will be sent to your device. Suppose, the CSC code of your Samsung device is INS(India) and you take it to the UK or Germany and use it there, you may not get official software updates from Samsung.

Checking CSC on Samsung devices

Using Software Information

There is another easier way to check the current CSC on your Samsung Galaxy device. Let’s see what is it:

  • Open Settings app.
  • About Phone > Software Information
  • Now, look for Service Provider tab SW Ver.
  • Thereafter, you’ll find your device’s CSC right after your device’s model number on the first line.


  • The first value of CSC, say INS, indicates the active CSC. This determines access to services and updates. You will receive updates through this channel. This is also the country for Samsung’s beta programs if you want to join one.
  • The second value “INS,INS” indicates that my Galaxy S9+ is a dual- SIM variant. If you are not using the second SIM slot, the second value replicates the first. This value only indicates which SIM you have in you, and does not affect any aspect of the experience.
  • The 3rd CSC value, which is again INS, indicates the country code; for which the Samsung device was manufactured and configured. This value cannot be changed and does not need to be.
  • If you receive the phone from a carrier, this value contains the locked CSC code. If the other values do not match, your carrier may deny warranty service.

Dialing Code

We can dial specific codes on our dialer to check the CSC. The code that we need to enter is #1234#. Once you enter ‘#’, you will see a screen like the one shown below. The first 3 letters after your device model form the CSC code for your device.

Using third-party provider

  • Download Phone Info app.
  • Thereafter install it.
  • Then, go to the CSC Code tab.
  • View the Active section CSC.
