For the past sixty years, NORAD (NORth American Air Defence Command) has been tracking him due to a simple mistake. Sear Roebuck and Company (now Sears) printed a phone number on where to contact Santa. Unfortunately, the number given, was that of NORAD instead of Santa. The colonel in charge realised what had happened, so started telling the children where he was according to the radar.
Now, with the internet, you can follow where he is and where he has been. Google has also jumped in on the act, so you have two ways that you can find him.
