Regular expression to detect few non characters

How do i do a regular expression that will allow everything except !@$%^&*()_+={}[]|:";'<>,.?/ (If i need to detect more than these can I simply add them into the regexp later?)

I intend using this to check if these character are present in postal addresses a user submits. So if they were there, I could reject the address.

Thanks

You should include allowed characters instead of excluding almost everything :

[\w+-]*

But if you want to really exclude those chars :

[^!@$%^&*()_+={}\[\]|\:";'<>,.?/]*
