How do I find out if an international address is correct/legitimate?

Question

I received a penpal letter 21 years ago from someone in Italy. I'm just getting around to writing back. (Yes, I have some procrastination issues, hush.) The back of the envelope got ripped off through the years of sitting in a cardboard box in storage and the only address I have to go off of is on the letter itself. Problem is I've never written to someone in Italy, I don't know if it's correct, looks backward. Here goes: Via del Patrocinio, 18 25100 Brescia
Do you think thats correct if I send it like that? Or am I missing something? (besides her name and the country)

Answer 1

That looks correct to me; I've never sent anything to Italy but have mailed things to other countries before.
I would suggest posting this question again in the Italy section of Yahoo! Answers, someone who actually lives there will be able to give you a better answer. Good luck!

Answer 2

One option would be to check on populare phone book site. Sites like Smartpages usually offer too look for someone by name or you can go backwards and input an address. Hopefully this helps!
