How to Read Samsung Galaxy Model Numbers

Sometimes you need to understand your Galaxy model number to be sure you’re getting the right case to fit.  For example in 2017 Samsung released two different versions of the Galaxy J3.  The first version was available only for certain mobile carriers in the US, and the second version was for general release.  Both were completely different dimensions so needed cases designed specifically to fit.

We’ve created this quick and easy guide to help you understand your Galaxy model number.

To check your model number go to Settings -> About Device -> Model Number

How do I Read the Model Number?

The Samsung Galaxy model number can be broken down into 5 parts:
