Postal Index Number - PIN Code - Decoding

https://factly.in/decoding-the-pincode-postal-index-number/

The link above indicates the meaning of PIN code. 

The First digit  represents the region the Value of 1 and 2 indicates it is North India, 3, 4 means the region is West of India, 5,6 means the region is South India and 7,8 means it is East of India. 

The Second digit represents the State and a sub-region with in a given state like 60 to 64 Tamil Nadu.

The Third digit represents the district with a State for (e.g) 625 002 indicates that it is Madurai District.

The last three digits represent the post office in the given district for example 625 002 (BIBIKULAM, Madurai).

Now, can we not extend this PIN Code to include the
Main Road,
Street Code,
Nagar Code,
and Door Number

That would mean the Postal Code would be enhanced further to include the above details .  This would mean the postal code would be a bigger digit may be 10 0r 12 digits or may be much bigger value,

What would this mean the To and From address can be simply  a unique numbers? 

The Post office can simply generate a QR code or a Bar Code for the from and to address for easy scanning and navigation.  The postal delivery man can now easily navigate to locate the address with a help of a POS system.

The Address then would be like as follows,
From
Karthikeyan Karuppanan
62500200005558994
To
My Belove Friend's Name
60055235561356222

The above pin code would be linked with GPS coordinates of the property. In case of emergency calls dialled from a smart phone the emergency response department would be able to get the location coordinates, pincode and the Address for immediate or asap response.

What do we think of this approach?  Will our Postal Department work this idea or proposal for ease of communication as many times people mis-spell the address.?

Ease of Communication
Better reach-ability
The Government and Other Service providers can track or log the movement of items to determine or ascertain the area as commercial, residential, compare the usage of posts, gifts, online orders, etc between areas to gather statistical data.
Change of address can be easily communicated and update with just one pin code.
The address column in the Passports and other shortened version of Smart cards can hold just the numbers and the POS device of the Officers can decode to get the full postal address.
This could then become a global norm of practice
