How STD Codes Are Distributed to States in India

STD (Subscriber Trunk Dialing) codes in India are assigned to different states, regions, and cities to facilitate efficient long-distance and intercity communication. The distribution is organized to manage the vast telephone network across the country.

Code Structure and Format

STD codes in India range from 2 to 5 digits, with the length generally reflecting the size of the area served. For example, a longer code may be used for a densely populated city, while a shorter code might be assigned to smaller areas. All STD codes begin with a '0' when dialed from outside the area.

Regional Allocation

Major cities like Mumbai, Delhi, Kolkata, and Chennai each have unique STD codes—022 for Mumbai and 011 for Delhi. States and union territories have been allocated a range of STD codes based on their geographical size and population density. For instance, Tamil Nadu has codes such as 044 for Chennai, while smaller states may have shorter codes.

Code Distribution Criteria

The allocation of STD codes is based on several criteria including population and demand. Larger cities and heavily populated areas are assigned more extensive code ranges to accommodate higher phone line volumes. Additionally, geographical size and administrative divisions influence the distribution of codes.

Code Assignment Process

The Department of Telecommunications (DoT), under the Ministry of Communications, manages the allocation and oversight of STD codes in India. The DoT periodically reviews and adjusts codes to address changes in population, administrative boundaries, and technological advancements.
