A List of Area Codes

I am looking for work. I am getting calls from recruiters from everywhere. They leave messages on my Skype account. I like to know which ones to ignore, since there are large parts of this country that I do not want to move to. I like to use area codes to get an idea of where the call is coming from. Granted, this does not always work since someone could use a cel phone with an area code for a prior residence. Still, I have decided to make a list of area codes on this site.
