where is 212-301-3470 located?

212 area code is New York City NY 

However the number itself does not give an address , maybe somebody
else has more luck

Google Answers policy prohibits a reseacher from giving out personal
information on a person, such as address, etc. Corwin is correct in
telling youthat 212 is a NY area code though. There are sites out
there that do offer a reverse phone # lookup.

Additionally, the 301 prefix indicates a lower Manhattan location, and
that prefix is registered to MCImetro of New York. More information is
not available for free, nor is there any guarantee that a paid search
will turn up further information, though you can try if you like.
