In the field of telecommunications in the UK, STD stands for 'subscriber trunk dialling' and is a hangover from the time when telephone users could 'phone straight through to a telephone controlled by another telephone exchange (prior to that, you had to ask the operator to put you through) The STD code is the first four (now five) digits of the full telephone number. The term STD is now a largely defunct term.
Sexual transmitted disease, dumb butt (:
I'm guessing that you mean STD = Subscriber Trunk Dialling (telephone area code) rather than STD = Sexually Transmitted Disease. STD code is another term used in some country for telephone area codes. The purpose of a telephone area code is to group telephone numbers by geographic area. In many cases, at least some calls to numbers with the same STD code as the caller can be dialed without the STD code, allowing shorter dialing sequences for many local calls.
In the UK, 0140 is an incomplete STD code (telephone area code); you need one more digit. In India, 0140 is an invalid STD code.
