India Area Codes / STDs

As you might expect for such a large country, India has many, many area codes covering all of its many cities and towns. Each unique India area code helps route inbound calls to a specific geographic area within the country.

Because of how local phone numbers are assigned in India, area codes apply only to India landline phone numbers. Mobile phone numbers do not utilize a separate area code - and the numbers shown here should not be used when calling mobile phones.

In India, area codes are also sometimes called STD codes or 'subscriber trunk dialing' codes. They are also sometimes referred to as SDCA codes - where SDCA stands for 'short distance charging area'.

Note that area codes in India vary in length from 2-digits to 4-digits. Since all India phone numbers are 10 digits in total, the local subscriber numbers associated with area codes vary in length accordingly. In other words, the local number in a 2-digit area code is 8-digits whereas 4-digit area codes are associated with 6-digit local numbers. more on India's local numbering scheme >>>>

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.
