Question : Add page numbers to pdf document

We convert scanned documents to pdf by using a converter.  Some of our users us the Adobe PDF Distiller which comes with Acrobat while others use the PDFCreator utility made b SourceForge.

What we need is to add page numbers to these documents.  I was hoping PDFCreator had the functionality natively but can't find it.  We have Standard versions of Adobe Acrobat version 5 and  9 on site as well as the latest version of PDFCreator.  Will these tools allow us to add the numbers?  If not are there others, preferable free, that will?
