Address Pattern Regular Expression

So I searched the internet for quite a while to find a street address regex that actually worked (and worked well). I didn’t manage to accomplish this, so I wrote my own. I’m keeping the address extraction algorithms and logic private, but I figured I could at least share the first part of the Regex:

Regex addressPattern = new Regex(@"(?[A-Za-z',.\s]+) (?([A-Za-z]{2}|[A-Za-z]{2},))\s*(?\d{5}(-\d{4})|\d{5})");

MatchCollection matches = addressPattern.Matches(text);

for (int mc = 0; mc < matches.Count; mc++)
{
string city = matches[mc].Groups["city"].Value;
string state = matches[mc].Groups["state"].Value;
string zip = matches[mc].Groups["zip"].Value;
}
