AddressData is a website I made that contains millions of addresses from cities around the world, along with city maps.

For example, here is what Seattle, WA, looks like.

This website also allows to search for addresses in a city and filter them. For example, here are addresses in Seattle, WA, where the postal code is 98125.

Try it out yourself at www.addressdata.net/United+States/Seattle~2C+Washington.
