I am setting up a form to collect postal addresses. Is there a way that I can add a validation to the text entry field that will allow recipients to enter a mix of numbers and letters (e.g. 10 Street Road) but prevent punctuation or special characters?

You can use custom validation and set it to the following regular expression - [^A-Za-z0-9].
