It is possible to have an automatic number generated for each submission. You can use Unique ID widget. This is good if you want to identify each form submission with a customized, unique and sequential identifier. Here's a helpful guide: Add Custom Unique IDs to your Form Submissions
You can also use the Random Value Generator widget on your form. The widget automatically generates a unique value based on the settings on the widget every time the form is opened.
