I have not been able to successfully retrieve code based on the Contact ID - but this post gave me a clue: Retrieving a phone number with ContactsContract in Android - function doesn't work

I have altered my original code to query on DISPLAY_NAME instead and things are working now. Here is the method I am using to retrieve the phone number:

     private String retrieveContactNumber(String contactName) {

    Log.d(TAG, "Contact Name: " + contactName);

    Cursor cursorPhone = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},

            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " = ? AND " +
                    ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
                    ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,

            new String[]{contactName},
            null);

    if (cursorPhone.moveToFirst()) {
        contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
    }

    cursorPhone.close();

    Log.d(TAG, "Contact Phone Number: " + contactNumber);

    return contactNumber;
}
