11 Digit STD and Phone Number Bangalore

11 Digit STD and Phone Number Bangalore: In today’s digital age, telecommunication plays a pivotal role in connecting people across distances. Bangalore, often referred to as the Silicon Valley of India, is no exception. With its bustling tech industry and growing population, the need for efficient and clear communication channels has never been greater. One key aspect of this is understanding the 11 digit STD and phone numbers in Bangalore.

What is an STD Code?

STD (Subscriber Trunk Dialing) codes are essential for making long-distance calls within India. Each city or region has a unique STD code that helps route calls accurately. For Bangalore, the STD code is 080. This code is crucial for anyone trying to reach a landline in the city from outside the local calling area.

The Structure of Indian Phone Numbers

Indian phone numbers can be categorized into landline numbers and mobile numbers. Traditionally, landline numbers have been shorter, usually consisting of the STD code followed by the subscriber number. Mobile numbers, however, are typically 10 digits long.

Landline Numbers in Bangalore

Landline numbers in Bangalore are formatted as follows:

STD Code + Subscriber Number

For example, if the subscriber number is 12345678, the complete number would be 08012345678.

Mobile Numbers

Mobile numbers in India are 10 digits long and do not require an STD code when dialed locally. However, when dialing from abroad or from a different state, the country code (+91) is added before the mobile number:


For example, a mobile number could be +91 9876543210.

Transition to 11 Digit Numbers

In recent years, there has been a transition to 11 digit numbering in certain contexts to accommodate the growing number of users. This includes the prefixing of a ‘0’ before mobile numbers when dialing from a landline within India. This change ensures uniformity and prevents confusion.

Example of 11 Digit Mobile Number in Bangalore

When dialing a mobile number from a landline within Bangalore, it would look like this:

0 + 10 Digit Mobile Number

This 11 digit format ensures that the call is routed correctly through the telecom network.

Importance of the 11 Digit Numbering System

The shift to an 11 digit numbering system has several benefits:

  1. Increased Capacity: It allows for a larger number of unique phone numbers, accommodating the growing population and the proliferation of mobile devices.
  2. Uniformity: It standardizes the dialing process, making it easier for users to remember and dial numbers correctly.
  3. Prevention of Number Exhaustion: With the increasing demand for new connections, the 11 digit system helps prevent the exhaustion of available numbers.
