Implementing RealTime Postcode Lookup Service API

So, are you looking for a efficient API for your company? Then keep reading! Continue to see how this API can be of use to you and how to implement it.

What is a Postcode?

A Postcode is a series of digits that identifies a location in the United Kingdom. It is also known as a postal code and is made up of a group of numbers separated by letters.

When was the first postcode introduced in the UK?

There were several attempts to introduce postcodes in the UK between the 1850s and early 20th century, but none was successfully adopted. The first effective postcode system was introduced by the Royal Mail in June 1959 as an experiment in Southampton. 
 In December 1963, the system was officially adopted across Britain and has been continually improved and expanded ever since. 
This system, known as the United Kingdom Postcode System, allows for efficient postal delivery across large regions with high volumes of mail. It works by dividing the entire country into smaller regions called sectors or post towns, which are identified by letters from A-O, followed by digits from 0-9.  According to this identification, mail can be sent to specific addresses within each sector or post town. 
Every address in the UK has its own unique postcode, which is used for mailing and parcel services. Every household also has its own main road address, which is frequently shared with neighboring houses. 
The postcode is often visible on the outside of the building where mail can be delivered directly. However, rural houses may have a mailbox outside where mail can be delivered. 

What is reverse geocoding?

Reverse geocoding is the process of determining a geographical location from either a latitude and longitude (lat/long) coordinate or a street address. 
Reverse geocoding may be useful when you need to find out where an address or lat/long coordinate is situated on a map. You can also use this information to convert coordinates into an address or vice versa if necessary.
