STD Code List of India: STD stands for Subscriber's Trunk Dialing, which is necessary for making long-distance calls within India. The STD code precedes the subscriber's landline number, allowing for direct calling without operator assistance. If, for instance, you want to call a landline number (247835) located in Chittoor, Andhra Pradesh, you first add the ISD code for India, which is +91 or 0, followed by the STD code for Chittoor (8572) and then the phone number: (+91 8572 247835 or 08572 247835).
