Digital Door Numbering: Simplifying navigation using a smart address

“Take the Left Opposite to the Bank and then take right. It’s the third house on your right.” These are some common ways in which we guide people to reach our home.

It could be a cab driver or a friend or someone who is visiting us fr the first time. This is usually the way in which we guide people to reach our houses in India. 
 
To ease this complexity in navigation, the Government of Andhra Pradesh has introduced the Digital Door Numbering System (DDN) which uses a smart address format - a Quick Response (QR) code which is unique to every household in the state. Once created, the code can be easily shared. This is an instant address that can be customised. 
 
Currently, the project is underway to cover households in 110 Urban Local Bodies (ULBs) in the state and streamline house numbers for easy navigation and better service delivery. According to government officials, the DDN is a unique scientific street-based addressing system that adheres to international guidelines.
 
Several other cities including Hyderabad, Bangalore, Berhampur (Odisha) across India are implementing the digital door numbering system. The West and other countries across the world already have a well-developed door and street numbering system. 
 
Interestingly, one of the earliest examples of house numbering system began in Paris in 1463. However, it only got streamlined in 1779 when a city guide Marin Kreenfelt hired a team of members to inscribe numbers of houses in Paris. Eventually, house numbering system became a crucial part of city planning across the world. 
 
Impact of Digital Door Numbering System 
  • Waste Management - Authenticated door-to-door garbage collection using DDN smart board
  • Emergency Response - Reduce fatality rates by up to 30% by routing emergencies to the door step with more clarity on reachability
  • Local Governance - DDN’s household communication network increases neighbourhood interactions, civic participation and creates hyper-local jobs
  • Public Distribution System - Smarter and accurate verification of household-level subsidies (such as BPL ration cards, LPG)
  • Boost Economic Activity - Enable local businesses to identify delivery points easily for better and faster service delivery
  • Efficient Electoral Rolls - Since the project is digitizing every street and home, electoral record keeping can be easier and cost efficient
