Every mobile device in the world has its unique ID which is a combination of Alphabetic and Numeric characters. To get the device’s Unique ID and we can use the react-native-device-info library.
The unique device ID is used to identify a device uniquely. For example, if you are making an application which requires a unique device dependent login mechanism like WhatsApp where you want the user to log in from a single device at a time then you can use device unique ID to track the single device login.
So let’s get started with the example to Get Unique ID of Device.
To Make a React Native App
Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install thereact-native-cli command line utility.
Open the terminal and go to the workspace and runnpm install -g react-native-clireact-native init ProjectNameInstallation of Dependency
To use DeviceInfo we need to install react-native-device-info package. To install this
Open the terminal and jump into your project
1 | cd ProjectName |
Run the following command
1 | npm install react-native-device-info --save |
This command will copy all the dependencies into your node_module directory, You can find the directory in node_module directory named react-native-device-info.
–save is optional, it is just to update the react-native-device-info dependancy in your package.json file.
Now we need to execute
1 | react-native link react-native-device-info |
This command will link installed package to our current react native project.

Now Open App.js in any code editor and replace the code with the following code.

To Run the React Native App
Open the terminal again and jump into your project using.cd ProjectNamereact-native run-androidreact-native run-ios (macOS only).
