The Indian Postal Code system plays a crucial role in the efficient functioning of the Indian postal system. The system is divided into various levels, with the state level being the primary level. Each state is assigned a unique two-digit code that is used in conjunction with the PIN code to identify the correct post office and delivery location. Within each state, the Indian Postal Code system is further divided into zones, sub-zones, and individual post offices. Each post office or delivery location is assigned a unique PIN code that reflects its location and jurisdiction. The PIN code is a six-digit code, with the first three digits representing the sorting district and the last three digits representing the post office or delivery location. To use the Indian Postal Code system by its state, you need to know the name of the state where the recipient is located. Once you have the name of the state, you can easily find the corresponding two-digit code using an online search tool or by referring to a printed directory. Including the state code in the address, along with the PIN code, is essential for accurate delivery and prompt service.
