Get the phone IMEI number (or serial number)

There are many ways to get the mobile phone IMEI no. You can follow any of this process:

Process 1:
TelephonyManager mngr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE); mngr.getDeviceId();

add READ_PHONE_STATE permission to AndroidManifest.xml

Process 2:
telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); deviceId = telephonyManager.getDeviceId(); Log.d(TAG, "getDeviceId() " + deviceId); phoneType = telephonyManager.getPhoneType(); Log.d(TAG, "getPhoneType () " + phoneType);

Process 3:
Also you can get the both IMEI numbers using the below code

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String imeiNumber1 = tm.getDeviceId(1); //(API level 23)   
String imeiNumber2 = tm.getDeviceId(2);

Process 4:

telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

    deviceId = telephonyManager.getDeviceId(); 
    Log.d(TAG, "getDeviceId() " + deviceId);


    phoneType = telephonyManager.getPhoneType();
    Log.d(TAG, "getPhoneType () " + phoneType);
