Local info you may want to know
Kolkata was India's capital until 1911 and retains a distinctive character unlike any other Indian city. It is the birthplace of Nobel laureate Rabindranath Tagore, the home of legendary filmmaker Satyajit Ray, and the epicenter of Durga Puja — a festival so grand that UNESCO recognized it as an Intangible Cultural Heritage of Humanity in 2021.
On the business side, Kolkata is the headquarters of several major Indian conglomerates and serves as the primary trade hub for eastern India, Nepal, Bhutan, and Bangladesh. The Salt Lake Sector V IT cluster and the newer New Town Rajarhat development have attracted major IT companies, making the city an increasingly important tech center.
Kolkata also hosts the oldest stock exchange in Asia (the Calcutta Stock Exchange, established 1908) and remains a significant center for tea auction, jute processing, and steel trading. The city's port on the Hooghly River is one of the oldest operating ports in India.
A genuine Kolkata IN phone number
Kolkata uses the telephone prefix 33, a two-digit area code that places it among India's most prominent cities in terms of telecommunications hierarchy. Only a handful of Indian cities have two-digit prefixes.
When dialing a Kolkata number from abroad, the format is: +91 (India's country code), followed by 33, then the 8-digit local number. From within India, callers dial 033 followed by the local number.
