Understanding PIN Code Zones Across Indian States
India's postal system assigns unique PIN codes (Postal Index Numbers) to different regions, helping streamline mail delivery. The country is divided into nine PIN code zones, including one functional zone for the Indian Army. Each state and union territory has specific PIN codes, covering cities, towns, and rural areas. Major states like Maharashtra, Uttar Pradesh, Tamil Nadu, West Bengal, Karnataka, and Gujarat have extensive PIN code ranges, while smaller states like Goa, Sikkim, and northeastern states have fewer codes. The first digit of a PIN code represents the region, ensuring efficient sorting and distribution of mail across India.
