Area Codes for Coimbatore and Nearby Locations

The area code used in the Coimbatore metropolitan area is: 422. Area codes for other locations near Coimbatore, Tamil Nadu are shown below.

In India, area codes are often called STD codes -- STD stands for 'subscriber trunk dialing'. To make things more confusing, they are also called SDCA codes. SDCA stands for 'short distance charging area'. So this means that in India:

area code = STD code = SDCA code

Coimbatore STD / area code

In India, area codes / STD codes are used somewhat differently than in other parts of the world in the sense that the physical area and/or population that they cover is often quite small. There is an historical reason for this that relates to an early technology limitation that now no longer exists.

Nevertheless, this old area code numbering scheme has stuck and as a result, India has hundreds and hundreds of STD codes -- many, many more than most countries.

Another somewhat unusual thing is that area codes / STD codes are used only for landline phone numbers in India. Mobile phone numbers in India do not utilize area codes. Instead, the mobile prefixes '9x' and '8x' are used for all mobile numbers regardless of where the subscriber is based.

This means that the listed Coimbatore area codes are only applicable to India landline phone numbers.

To make an inbound international call (or domestic long distance call) to a Coimbatore landline phone, you need to dial a 3-digit area code, along with a 7-digit local subscriber number - 10-digits total.

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

  • For areas with 2-digit STD codes: Subscriber numbers for areas with 2-digit area codes are 8-digits long (10-digits total).
  • For areas with 3-digit STD codes: Subscriber numbers for areas with a 3-digit area codes are 7-digits long (10-digits total).
  • For areas with 4-digit STD codes: Subscriber numbers for areas with 4-digit area codes are 6-digits long (10-digits total).

In all 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.

Please check India's official National Numbering Plan (large pdf) for a complete list of India area codes / SDCA codes.

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. The city code for Coimbatore is CJB.
