How to Fix Word Index Page Numbers After Updating an Index

Product: Word
Device & OS: not provided
Scenario: Updating an existing index field in a multi-section document.
Observed behavior: Updating the index deletes and reinserts continuous section breaks, which merges page number settings from surrounding sections and causes the page numbers to display incorrectly.

Before you start

Enable the 'Show/Hide ¶' feature in the Home tab to easily see all hidden section breaks and formatting marks in your document before attempting to fix the index layout.

Solution 1Recommended

Reconfigure Section Breaks and Page Number Formats

Manually insert a correctly configured section break before the index and reset the page numbering options prior to updating the field.

When you update an Index field, Word automatically deletes and reinserts continuous section breaks. Because section formatting is stored in the break at the end of a section, this process can merge settings and disrupt your page number restarts. You must manually control the section breaks to retain your intended pagination.

Enable Section Tracking

Right-click the bottom status bar in Word and check 'Section' to display the current section number. This helps track exactly which section you are modifying.

Locate Existing Breaks

Scroll to the area immediately preceding your index and inspect the existing section breaks using the Show/Hide ¶ formatting marks.

Insert a New Section Break

Go to the Layout tab on the ribbon, click 'Breaks', and select a 'Next Page' or 'Continuous' section break to place right before the index.

Format Page Numbers

Double-click the header or footer area to open the Design tab. Click 'Page Number', select 'Format Page Numbers', and configure your desired number format and restart options (e.g., 'Continue from previous section').

Update the Index Field

Right-click anywhere inside the generated Index and select 'Update Field' to refresh the index with the corrected page numbers.

Reconfigure Section Breaks and Page Number Formats

Understanding Section Breaks: Deleting a section break applies the page layout settings of the following section to the preceding text, which is why formatting suddenly changes during an index update.

Frequently Asked Questions

Why do my page numbers change to Roman numerals in the index?

This happens if the section break before the index inherits settings from a previous section (like a preface or table of contents) that uses Roman numerals. You can fix this by double-clicking the footer in the index section, going to Page Number Format, and changing the number format back to Arabic numerals (1, 2, 3).

How do I show hidden section breaks in my document?

Go to the Home tab and click the paragraph symbol (Show/Hide ¶) in the Paragraph group. This toggle displays all hidden formatting marks, including section breaks, allowing you to easily select, delete, or manage them.

Does updating the Table of Contents cause the same section break issue?

Updating a Table of Contents typically does not delete and recreate section breaks in the same way an Index field does. However, if your TOC is wrapped tightly between specific section breaks, it is always best practice to verify page number formatting after performing a full update.
