From Royal Mail UK:
Post Code can have 6 to 7 characters separated by space in between, like
3 or 4 characters before the space is Outward Code. This contains information about the area and the district to which the mail is to be delivered.
3 characters after space is Inward Code, used to identifies the sector and one or more properties in that sector.
[Note : Some documents online – says inward code used to identify a street or a group of building, not a specific building or a person.
Some organization and large size commercial building may have their own specific Post Code]
Lets jump to the POC.

Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device launched in September 2008.
