You can easily eliminate page numbers either throughout your entire document, or only on selected pages.
In order to prevent page numbers from appearing on the pages of your LaTeX document, you should include the line
after your \documentclass line.
This will prevent page numbers from being printed on all of the pages.
If you wish to just prevent page numbers from printing on one page, you should put the line
in the text of the page you want to be printed without a page number.
