Unfortunately there is no such functionality for a field on the form. The most that you can do for validation is to use the Input Mask option of the field.
I can see on your form https://www.jotform.com/70044448241651 that you have already done this.
There is though another field that have validation feature. It is the Email Validator widget
Hope this help. Let us know how we can be of further help.
