How do I create a form with a location constraint?

I am designing a website for a local organization, and they want to make it so when you sign up, you have to enter your address, and if it isn't in a certain radius, it is denied. Is there a way I can create this, then embed it into a wix or squarespace site? I would need the whole form to be embedded. Thanks for any help!
