Ancient Period in Indian Postal Code History (321 BCE)
How Indian Postal Code History Began
First, Indian postal code history starts in 321 BCE. Specifically, it began with Chandragupta Maurya. Also, his empire used runners and horses. For example, they carried royal messages far.
In addition, relay stations had fresh horses ready. Notably, the Arthashastra book describes this system. Therefore, it had strict delivery rules. Thus, this was the true beginning.
Key Features of Ancient System
| Feature | Detail |
|---|---|
| Start year | 321 BCE |
| Method | Runners and horses |
| Speed | 100 km per day |
| Users | Only royalty |
For instance, Emperor Ashoka used this system. His messages reached all of India.
Mughal Period in Indian Postal Code History (1526-1857)
How Mughals Shaped Indian Postal Code History
Next, Indian postal code history grew under Mughal rulers. For instance, Emperor Sher Shah Suri built the Grand Trunk Road. The road stretched 2,500 km. Moreover, it had postal stations every 2-3 km.
Specifically, these stations were called “dak chowkis.” Furthermore, they kept horses ready 24/7. As a result, a message from Delhi to Agra took 6 hours. Thus, the Mughal system was very fast.
Key Features of Mughal System
| Feature | Detail |
|---|---|
| Road length | 2,500 km |
| Stations | 1,000+ dak chowkis |
| Speed | 150 km per day |
| Users | Royalty and merchants |
British Period in Indian Postal Code History (1766-1947)
When Modern Mail Started
Later, Indian postal code history entered a new phase. So, the British started “Company Mail” in 1766. Specifically, Lord Clive began this system.
Then, in 1774, Warren Hastings opened Calcutta GPO. Notably, this was India’s first GPO. After that, Madras GPO opened in 1786. Finally, Bombay GPO opened in 1794.
The Indian Post Office Act of 1837 unified all systems. Later, Sir Henry Frere modernized everything in 1854. He introduced cheap stamps. For example, a stamp cost just 1/2 anna.
For the first time, common people could mail letters. Thus, this changed Indian postal code history forever.
Key Features of British System
| Feature | Detail |
|---|---|
| Start year | 1766 |
| First GPO | Calcutta (1774) |
| First stamp | 1854 |
| Post offices by 1900 | 10,000+ |
Additionally, Railway Mail Service started in 1854. Consequently, trains made delivery fast. As a result, delivery dropped from weeks to days.

Why India Needed a Postal Code (1947-1972)
Problems That Shaped Indian Postal Code History
After independence in 1947, India grew fast. Specifically, the postal system became overwhelmed. For example, there were 23,000 post offices by 1960.
However, sending a letter took 2-3 weeks. Also, manual sorting caused many errors. Therefore, India needed a modern solution.
So, the government appointed a committee in 1961. Specifically, Shriram Bhikaji Velankar led the team. Finally, after 11 years, the PIN code was ready.
The Birth of PIN Code in Indian Postal Code History (1972)
When PIN Code Was Launched
On August 15, 1972, India got its PIN code. PIN stands for Postal Index Number. Specifically, Prime Minister Indira Gandhi launched this system.
Notably, India became one of the first Asian countries with a postal code. Thus, this was a proud moment.

Why 6 Digits?
The 6-digit system was designed by Velankar. Specifically, each digit has a meaning:
| Digit | What It Means |
|---|---|
| 1st | Postal zone (1 to 9) |
| 2nd | Sub-zone or circle |
| 3rd | Sorting district |
| 4th-6th | Specific post office |
For example, PIN 110001 breaks down as:
- 1 = Northern zone
- 1 = Delhi circle
- 0 = Central district
- 001 = Connaught Place PO
Thus, 110001 was India’s first PIN code.
The 9 Postal Zones
Here are the 9 zones created in 1972:
| Digit | Zone | States |
|---|---|---|
| 1 | North | Delhi, Haryana, Punjab |
| 2 | North | UP, Uttarakhand |
| 3 | West | Rajasthan, Gujarat |
| 4 | West | Maharashtra, Goa |
| 5 | South | Karnataka, Andhra |
| 6 | South | Tamil Nadu, Kerala |
| 7 | East | West Bengal, Assam |
| 8 | East | Bihar, Jharkhand |
| 9 | Army | Army Postal Service |
So, the first digit tells you the region. Therefore, this made sorting 90% faster.
