Many situations are that emergency services do not know where the addresses are
if you simply tell them your common addresses because the streets and streets
numbers are not regularly distributed like a random arranged words list which
needs lot of time for people to find a specific word among them.  If you know
the exact location of an address on the map, you will feel easily to find the
optimized way to reach that.  It never means the search is performed by a
ROBOT who has simple mechanical thought and tries to follow the grid lines.

It can be proved that the natural area coding system has the minimum characters
to represent a location with the same resolution using the most common characters:
digits and Latin alphabet without the chance to form bad meaning words or phrases.

In fact, many government departments, companies, individual people need an area
coding system in order to speed the location of addresses.  The existing postal
code system seems to serve only the post offices and many others create their
own systems.  It is extremely inconvenient for them to communicate with each
other and with their customers.  It is the time to unify all these systems
by introducing a best system which is not only convenient for professional
groups with computers but also for ordinary people simply equipped with
their brain and maps.  The natural area coding system is just such a system
which can represent each area less than 50 by 25 meters all over the world by
only eight most familiar characters.  Each building and one or two houses can
have a unique natural area code and people can easily remember their codes
because of the reasonable number of characters and its multiple usages and frequent
referrings.
