Type a city name or an STD code above — results appear as you type.
How to use this STD code finder
- To find a code: type the city name in the first box. Suggestions appear as you type — Bengaluru gives 080.
- To find a city: type the code in the second box, with its leading 0 — 011 gives Delhi.
- Some codes serve more than one city (0120 covers Noida and Ghaziabad); the result lists them all.
- Then dial using the guide below: the full code from inside India, or the code without its 0 after +91 from abroad.
How to dial
Worked through for a Delhi landline number 4155 1234: from a phone anywhere in India you dial 011 4155 1234. From London, New York or Dubai you dial +91 11 4155 1234 — country code 91, then the code with its trunk 0 dropped. Dropping the 0 from abroad, and keeping it at home, is the whole trick. Mobile numbers are simpler: 10 digits inside India, and +91 plus the 10 digits from abroad, with no STD code ever.
How it works
STD codes were assigned city by city as India's landline network grew: the biggest metros received short two-digit codes after the 0 (Delhi 011, Mumbai 022, Kolkata 033, Chennai 044), and smaller cities received three or four digits. The codes follow telephone circles drawn decades ago, which is why neighbours sometimes share one code — and why a code tells you the region of a landline but never its exact address. Landlines are slowly giving ground to mobiles, but offices, hospitals, schools and government departments still publish landline numbers, so the codes remain in daily use.

FAQ
What is an STD code?
An STD (Subscriber Trunk Dialling) code is the area code for landline phones in an Indian city. You dial it before the landline number when calling from another city: Delhi is 011, Mumbai is 022, Bengaluru is 080. Mobile numbers do not use STD codes — they are dialled as the plain 10 digits anywhere in India.
How do I dial a landline in another Indian city?
From anywhere in India, dial 0, then the STD code without its leading 0 — actually the STD code already includes that 0 in the way it is written. In practice you dial the full STD code as shown (for example 011) followed by the landline number: 011 + the 8-digit Delhi number. From a mobile, the same full sequence works.
How do I call an Indian landline from abroad?
Dial your country's exit code (or +), then India's country code 91, then the STD code WITHOUT its leading 0, then the landline number. For Delhi that is +91 11 followed by the landline number. The leading 0 is only for calls made from inside India — this is the step most people get wrong.
Why do Noida and Ghaziabad share the code 0120?
STD codes follow telephone circles, not city limits. Noida, Ghaziabad and nearby towns sit in the same circle, so they share 0120. A few other codes are shared by neighbouring cities too, which is why the code search on this page can return more than one city.
My city is not in the list. Why?
This page covers 60 major Indian cities — the ones people search for most. India has hundreds of smaller STD areas, and a complete official list is maintained by the Department of Telecommunications and BSNL. If your town is missing, its code is usually the same as the nearest large city in the table, but do check the official list for certainty.
What is the difference between an STD code and a PIN code?
They solve different problems: an STD code routes a phone call to a city, while a PIN code routes a letter or parcel to a post office. Delhi's STD code is 011 and its main PIN code is 110001. Our PIN Code Finder covers postal codes for major cities if that is the number you need.
