Anything in the USA starting with 555 is a fake number. It's a prefix the USA has set aside for movies and such. 212 is a New York area code, but the rest of the number is bogus. Sorry to burst the bubble.

Although, I am certain there are services like this. I think the idea is definitely a good one. Unfortunately, it violates a few prostitution rules, safety codes and whatnot. It would never go over in the USA.

Maybe I should look at starting this sort of thing in Canada. Hehehe...
