The USA does have zip+4 which is an extension on the zip code system and sounds like it’s about as specific as the UK one. https://en.m.wikipedia.org/wiki/ZIP_

  In some cases, your zip+4 is uniquely your address, too. My townhouse was a new development and after complaining for over a year that I wasn't able to sign up for Informed Delivery, I was assigned a new unused +4. That said, most people don't use the +4 when getting directions or the like, it's just used for postal service.

    > it's just used for postal service Even then, to my understanding the USPS has for some time now not relied on zip codes at all. They have a really good address database, they match on that, and then stamp the mail with a routing barcode at the origin post office. The zip code is extra, mail flows just fine if you leave it off.
