Your question is not clear.

There are tables of area codes for each country. See the related links below for examples.
STD, or Subscriber Trunk Dialling, began in the UK in 1958.
It depends on what country. There are lists of STD Codes (telephone area codes) for different countries on a variety of websites. See the related links below for a few examples.
"STD code" is an alternative name for an "area code" in the United Kingdom and several other countries. It comes from the phrase "Subscriber Trunk Dialling." A 5-digit STD code is simply an area code in the UK that has 5 digits. The 0 is not included as a part of the area code. The 0 is dialled within the UK to signify a long-distance call. The 0 is not dialled on a call from abroad. There are only 12 such area codes. 013873 - Langholm 015242 - Hornby-with-Farleton 015394 - Hawkshead 015395 - Grange-over-Sands 015396 - Sedbergh 016973 - Wigton 016974 - Raughton Head 016977 - Brampton 017683 - Appleby-in-Westmorland 017684 - Pooley Bridge 017687 - Keswick 019467 - Gosforth Note that India also uses the term "STD Code" for its domestic telephone area codes, and India has many STD codes that are 5 digits or longer.
