Users can choose between voice input mode or typing mode. For voice input mode, users can quickly input an address through the voice input function on their devices. When they enter a street name or street number with name, the relevant round number for the address will show in the search result. For typing mode, users only need to type in the first three letters of the address then a dropdown list with all the possible addresses will appear. Users can then choose the address from the list. The result will show the round number. If more than one round number appears in the result, users can reduce it by typing in a street number.
