Unfortunately no. The K3 had them, but more recent readers do not. The Fire does not have it either.

The Touch displays Location # at bottom left of each eBook page and % read at the bottom right. If you display the Menu, then Page # will display at bottom center of the Menu window, that is if page numbers have been added by the publisher. Also, if you display the TOC it will show Page # to the right of all entries. The TOC use of page numbers is the greatest use of such IMO. Page numbers in a TOC make a lot of sense and add a lot of value, again IMO.
