Addresses are generated from real streets in the selected state.
How house numbers work：Numbers are picked from the gaps between real house numbers on the same street, so the address sits in a real range and passes format checks — but nobody lives there. No names, phones or personal data.
A random real street from the 5 tax-free states, house number synthetic.
