How can I generate a unique ID number for every entry?

All Cognito Forms entries automatically have their own unique ID number based on the order that they were submitted in.

You can reference this number in calculations and in other places on your form (such as the form confirmation page) using the expression: =Entry.Number

If, however, you want to create a custom unique ID - you can do that too.
