When you are ready to restart numbering, you can use the technique above, or you can place your cursor inside a numbered paragraph above, click the Format Painter (the paintbrush icon on the Home tab under Clipboard), then click on the line where you want to restart numbering. Using Format Painter this way solves several paragraph numbering problems (the number sequence, indents, and inter-paragraph spacing) simultaneously.
A best practice that we recommend to our clients is to create a base/folio master –with styled and positioned footers and current page number special characters– on which all other masters are based. This allows a footer that may contain date or issue information to be updated once and the changes are reflected in all of the master pages. If your masters only have current page number special characters then you can just add them to each master and the page numbers will be reflected when each master is applied to your document pages. document numbering in indesign
