A Serial number PDF is a unique sequence of numbers assigned to the completed PDF form for the purpose of identifying a specific form submission. When users submit a web form, a serial number will be assigned automatically to the appropriate PDF field. The serial number changes in increments of one each time a form is submitted (e.g., if starting serial number is 10000, the next form submission will have a serial number of 10001).

To setup a serial number PDF, you will need a fillable PDF form configured with a web form (see how to create fillable PDF forms). Additionally, you will need a serial number PDF field on the fillable PDF form.


  1. Create the web form and the fillable PDF with matching form components/PDF fields. On the web form, do not create a serial number form component.

  2. Match the PDF fields with the form components (see how to create fillable PDF forms). This should leave the serial number PDF field unmatched.
    Except for serial number PDF field, all other PDF fields are matched with its form components.
