These STD (Subscriber Trunk Dialing) codes are a set of numbers that have to be affixed before a landline telephone number, if you want to dial it from another Indian city. ISD (International Subscriber Dialing) code, on the other hand, is a set of numbers that has to be added before the STD code of a particular city, if you want to make a call to a number from outside India.
