How to apply a characters limit to form fields such as address and phone number fields?

I don't see any way to put format restrictions on the off the shelf Address and Phone Number inputs. i.e. I can enter as many numeric characters as I want for Zip Code, same with Phone Number, etc. I'm assuming this has something to do with ensuring it's flexible for internationalization but I would have also assumed that you could set format requirements on the fields themselves (as you can do with say the Text input). Is there no way to do this? If not, does everyone just run the risk of getting garbage address and phone data? 

In the address field you cannot set a characters limit, your users are free to enter the needed number of characters, if you would like to limit the number of characters for an specific field in the address field, you would need to switch to use Text Boxes, this way you can set up separated limits or masks to each field: 

Regarding to the Phone Number field, you can only set up a mask that will limit the entry the number of characters you have allowed in the mask:
