Fix Missing Numeric Tab in PDF Form Field Properties
Question details
Users cannot find the Numeric formatting options in form field properties after converting a Word document into a fillable PDF.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to edit properties for a specific text field in a newly converted fillable PDF.
- Observed behavior
- The Numeric tab or format option is entirely missing from the form field properties, preventing users from restricting field input to numbers.
Ensure your PDF editor is currently operating in 'Prepare Form' mode, as advanced form field properties are hidden during standard document viewing.
Revert Form from Signature-Oriented to Standard
Converting your document back to a standard form removes signature workflow restrictions, restoring missing formatting tabs.
When a Word document is converted into a fillable PDF, the software may automatically detect signature lines and trigger a 'Need Signatures' workflow. This locks down specific form fields to maintain document integrity, which hides options like the Numeric format.
Disabling this specific workflow converts the fields back into standard interactive forms, returning all property options to normal.
Open your document and select the 'Prepare Form' option from the right-hand tools pane.
Locate and click the 'More' button (often represented by a wrench icon or three dots) situated just above the list of form fields.
Click the option to convert the document to a standard Acrobat form, or disable the 'Need Signatures' workflow.
Right-click your desired form field, select 'Properties,' navigate to the 'Format' tab, and verify that the 'Number' category is now available.

Manually Replace with a Standard Text Field
If you only need numeric formatting on a few fields, deleting the restricted fields and manually drawing standard text boxes bypasses the issue.

Frequently Asked Questions
Why did my Word-to-PDF conversion create a signature-oriented form?
PDF conversion software often scans for keywords like 'Signature' or 'Sign Here' in your Word document. If detected, it may automatically trigger an e-signature workflow, which locks down standard form fields to prevent document tampering, subsequently hiding tabs like 'Format' or 'Numeric'.
Where is the Numeric formatting option usually found in PDF properties?
In most standard PDF editors, numeric settings are not found in an independent tab. You must open the form field 'Properties', navigate to the 'Format' tab, and select 'Number' from the 'Select format category' dropdown menu.
Can I format a signature field to only accept numbers?
No. Signature fields are strictly designed by the PDF standard to capture digital or electronic signatures. If you need a user to input a specific number, such as an ID, quantity, or date, you must use a standard text field and format it for numeric input.
