Area Codes for Kolkata and Nearby Cities

Despite it's very large population, Kolkata proper currently has only one area code. Area codes for several locations near Kolkata are shown below.

Area codes are also sometimes called STD codes or 'subscriber trunk dialing' codes. In India, area codes are also known as SDCA codes. SDCA stands for 'short distance charging area'.

Kolkata area code / STD:   33 

Area codes are generally used to route inbound calls to a specific geographic area within a country. However, in India, mobile phone numbers do not utilize area codes, so the area code above applies only when dialing landline phones in Kolkata.

To make an inbound international call (or domestic long distance call) to a Kolkata landline phone, you need to dial this 2-digit area code, along with an 8-digit local subscriber number - 10-digits total.

If you are calling a Kolkata mobile phone number, you should not use this area code. Click here for further details on dialing a Kolkata mobile phone number - and for information on how to tell a landline number from a mobile number.

Area Codes for Cities Near Kolkata

Several cities and towns near Kolkata have their own distinct area codes, aka STDs or SDCAs.

Here are the area codes for several locations near Kolkata:

Location Area Code
Kolkata area code  33

  • 3-digit area codes (SDCA codes): Subscriber numbers for the areas cited above with 3-digit area codes / SDCA codes (e.g., Navi Kolkata, Kalyan) are 7-digits long, not 8-digits as in Kolkata proper.
  • 4-digit area codes (SDCA codes): Subscriber numbers for the areas cited above with 4-digit area codes / SDCA codes (e.g., Bhiwandi, Dahanu) are 6-digits long, not 8-digits as in Kolkata proper.

In both cases, these numbering rules allow the final complete phone number to conform to the required 10-digit telephone number format that is standard throughout India for landline phones. Mobile phones are also currently 10-digits long, but that will be changing in 2009 when 11-digit mobile phone numbers are implemented.

In some cases, area codes may be referred to as city codes. However, a 'city code' more correctly refers to the codes used for airports and other geographic designations under the UN's UN/LOCODE system and/or the IATA airport coding system.
