Where is telephone area code 001 845?

Answer 1

That depends on what your international dialing prefix is.

If your international dialing prefix is 00, then you're asking about country code +1 (North America, including USA, Canada, etc.), area code +1 845 (suburbs north and northwest of New York City).

If your international dialing prefix is 001, though, you're asking about country code +84 (Vietnam), and an area code beginning with 5 (somewhere roughly in the middle of the country, 1 or 2 more digits needed to be more specific).

Because of the confusion introduced by the international access prefix, it is best to quote an international telephone number beginning with the actual country code (never, ever begins with a zero), omitting any access prefix.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)

Answer 2

Northern suburbs of New York City, including Poughkeepsie and West Point, but not including Westchester County (area code 914)!
