You insert a new figure or table in a Word document, add a caption with a number, and then update the table of contents expecting to see the new caption. Instead, the TOC either shows the old numbers or omits the new entry entirely. This problem occurs because Word’s TOC and caption fields rely on separate field codes that update on different triggers. This article explains why the TOC misses new caption numbers and gives you the exact steps to force a full update of both fields.
Key Takeaways: Fixing Word TOC Caption Number Updates
- Ctrl + A then F9 (or Ctrl + Shift + F11): Forces a full update of all fields including TOC and caption SEQ codes.
- Right-click TOC > Update Field > Update entire table: Refreshes only the TOC field, not the underlying caption SEQ fields.
- File > Options > Display > Update automatic links at open: Prevents stale caption numbers when reopening a document.
Why Caption Numbers and TOC Entries Become Out of Sync
Word stores caption numbers inside SEQ (Sequence) field codes. When you insert a caption using Insert > Caption, Word places a SEQ field inside the caption text. The TOC itself is a TOC field code that reads those SEQ fields to build its entries. The two field types update independently. Pressing F9 on the TOC updates only the TOC field — it does not force the SEQ fields to recalculate. If you added a new caption after the last full field update, the SEQ fields still hold the old numbering. When the TOC reads them, it retrieves the outdated numbers or skips the new entry entirely if the SEQ field has not been refreshed.
A second cause is the order of field updates. Word processes fields in a top-to-bottom, left-to-right order within a single update pass. If the TOC field appears before the new caption in the document, Word may update the TOC before the caption’s SEQ field has been recalculated. This produces stale or missing entries.
A third cause involves the Field shading and Field codes display settings. When field codes are visible, the TOC may display the field code text instead of the results. This does not affect the numbers directly but can confuse users who see { TOC \o "1-3" } instead of the actual table.
Steps to Force a Full Update of Caption Numbers and the TOC
- Select the entire document
Press Ctrl + A to select all text, tables, and fields in the document. This ensures that every field code is included in the update. - Update all fields at once
Press F9 (or Ctrl + Shift + F11 on some keyboards). Word updates every selected field in order: first all SEQ fields (caption numbers), then the TOC field. This forces the TOC to read the freshly recalculated numbers. - Verify the TOC update dialog
If the TOC still shows old data, right-click inside the TOC and select Update Field. In the dialog, choose Update entire table and click OK. This step is redundant after step 2 but confirms the TOC field itself refreshes. - Check for locked fields
If captions still do not update, press Ctrl + A then Ctrl + Shift + F11 to unlock all fields. Then press Ctrl + A then F9 again. Locked fields prevent the SEQ code from recalculating. - Toggle field codes off
Press Alt + F9 to toggle all field codes off. If field codes were displayed, the TOC might show the field code syntax instead of the results. Toggling them off forces Word to display the updated field results.
Update on Document Open
To avoid stale caption numbers every time you open the document, configure Word to update fields automatically.
- Open Word Options
Go to File > Options > Display. - Enable automatic update
Check the box labeled Update automatic links at open. Click OK. This setting forces Word to refresh all fields including SEQ and TOC when the document loads.
If the TOC Still Misses Caption Numbers After Updating
The caption was inserted after the TOC was generated
If you insert a new caption after the TOC already exists, the TOC field may not recognize the new SEQ field if the caption is placed outside the TOC’s defined heading range. The TOC field code includes a switch like \o "1-3" which limits entries to headings styled with Heading 1 through Heading 3. Captions are not headings. To include captions, you must use a different TOC switch: \c "SEQ Table" or \c "SEQ Figure".
To fix this, delete the existing TOC, insert a new one using References > Table of Contents > Custom Table of Contents, and in the dialog click Options. Under Table entry fields, check the box for the caption label you use (Figure, Table, or Equation). Word then builds the TOC from the SEQ fields of that label.
The SEQ field is inside a text box or table cell that is not in the main story
Word’s TOC field reads only the main document story by default. If your caption is inside a text box, a table cell in a nested table, or a header/footer, the TOC may skip it. Move the caption to the main body text or use a cross-reference field instead of a TOC for those items.
The TOC field is corrupted
If the TOC field code is damaged, it may not display any entries. Press Alt + F9 to view the field code. It should look like { TOC \c "Figure" \h \z \u }. If the code contains extra characters or is missing the backslash switches, delete the entire TOC, then insert a new one from References > Table of Contents.
Manual Update vs Automatic Update: Behavior Differences
| Item | Manual Update (Ctrl+A, F9) | Automatic Update at Open |
|---|---|---|
| Scope | All fields in the selection | All fields in the entire document |
| SEQ field refresh | Forces SEQ recalculation before TOC | Refreshes SEQ and TOC in document order |
| User action required | Must remember to do this after every edit | Happens silently on open |
| Works with locked fields | No — must unlock first | No — locked fields are skipped |
| Best for | Immediate verification during editing | Ensuring consistency on shared or printed documents |
Manual update gives you full control over the order of field recalculation. Automatic update is convenient but may fail if any field is locked or if the document contains fields in headers or footers that are not part of the main story.
Conclusion
You can now fix a Word TOC that misses newly inserted caption numbers by selecting the entire document and pressing F9 to update all fields in the correct order. For ongoing accuracy, enable File > Options > Display > Update automatic links at open. If captions still do not appear, verify that the TOC is configured to include the correct caption label using References > Table of Contents > Custom Table of Contents > Options. A final tip: use the keyboard shortcut Ctrl + A then F9 before printing or saving to PDF to guarantee all numbers are current.
