When you import your Aadhar card from DigiLocker, the Aadhar number is pre-masked by DigiLocker. However, you have the option to manually enter your Aadhar number, which allows you to view and copy it when needed.

Additionally, you can enable the option to mask or unmask the Aadhar number using your device lock. To set this up, go to Menu > Security and enable it under the 'My Cards' option.
