No it isn't and it's not sold as tracking either. It's called "delivery confirmation" which only means just as it says, it will post when the item was delivered. And keep in mind that "delivered" does not mean signed for, it means delivered with the rest of the mail. Priority Mail is simply First Class mail, nothing more!
If you want true tracking you have to specifically request registered or certified or send the item Express Mail.
Hint: for short distances, say less than 100 miles or so, you can send an item UPS Ground and it usually gets there the next day or day after. It's very fast.
