Do You Have To Pay To Join Google's Adsense Program?

I thought that everybody already knew the answer to this but I was wrong because I saw someone post this question on another forum. So here is the answer for the record:

No you do not have to pay any money to join Google's Adsense program. However what you will need is a website or blog that has some content on it because when you sign up for the Adsense program you are going to have to submit the url of your site so that Adsense can review and approve it.

But you don't have to pay any money to sign up for the Adsense program. However what may give you cause for c0ncern might be the fact that Adsense will ask for information from you like your social security number - they will need that information because if you make over a certain amount of money then that amount has to be reported to the IRS.
