Area Codes for Ludhiana and Nearby Locations
The area code used in the Ludhiana metropolitan area is: 161. Area codes for other locations near Ludhiana, Punjab 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
Ludhiana 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 Ludhiana area codes are only applicable to India landline phone numbers.
