You can change document numbering options when you choose Layout > Numbering & Section Options or when you choose Document Numbering Options from the Book panel menu.

Automatic Page Numbering

Select if you want the page numbers of the current section to follow the numbering of the previous section. Using this option, the page numbers in the document or section update automatically when you add pages prior to it.

Start Page Numbering At

Type the starting number for your document or for the first page of the current section. For example, if you want to restart the numbering for a section, type 1 . The remaining pages in the section will be renumbered accordingly.

Note: If you chose a non-Arabic page-numbering style (such as Roman numerals), you still must type an Arabic numeral in this box.

Section Prefix

Type a label for the section. Include the spaces or punctuation you want to appear between the prefix and the page number (for example, A–16 or A 16). The prefix is limited to eight characters. It cannot be empty, and you cannot enter a blank spaces by pressing the spacebar—copy and paste a space character from the document window instead. Note that plus (+) or comma (,) symbols cannot be used in section prefixes. (See Insert white space characters.)

Style (page numbering)

Choose a page-numbering style from the menu. The style applies to all pages in this section only.

Section Marker

Type a label that InDesign inserts on the page at the location of a section marker character that appears when you choose Type > Insert Special Character > Markers > Section Marker.

Include Prefix When Numbering Pages

Select if you want the section prefix to appear when you generate a table of contents or index, or when you print pages that contain automatic page numbers. Deselect this option to display the section prefix in InDesign but hide the prefix in the printed document, index, and table of contents.

Select this option to number chapters sequentially in a book.

Same As Previous Document In The Book

Select this option if the current document is part of the same chapter as the previous document in a book.
