If I had only a ZIP+4 Code Could I Look Up An Address?

Subject says it all.

What else do you have? Name? phone number? general idea of where the house is?

I mean, with just the zip code, there’s not much you can do other then narrow it down to a few cities.

Each ZIP+4 is tied to a specific building, I just don’t know if you can actually find a listing for this.

Not on any utilities provided on the USPS website, no. It will tell you city and state, no more.

Try the following site. I have no affiliation with the site and can’t vouch for its accuracy. I did plug in my own zip+4 and it returned a range of addresses on my street. It looks like there is a paid version that may (or may not) provide the exact address.

Just ran my building (without my apartment number) on the USPS website. Some apartments seem to have unique ZIP+4s, but most are a range. My floor has two +4s, one for apts. A & B, the other for C through M.

So most likely no, you couldn’t find a precise address from a ZIP+4, assuming that some reverse lookup tool were publicly available.

LawMonkey,
Your apartment isn’t a building, just an element of it.
If you have a freestanding house or commercial building, that will identify your location rather precisely.

No, it’s not always a specific building, but it can be a small range of addresses. In residential areas, for example, it’s often a block (a stretch of a street between two intersections).

Back in the 1980s and 1990s, every local post office would have Zip+4 directories available to the public, where you could look it up either way, by street address or by Zip+4. The latter would list all the specific addresses for each Zip+4. I have no idea whether this still exists or if it is in electronic form.

Okay, thanks.
I’ll consider this topic closed.

Huh, I didn’t know the +4 narrowed things down so far. I’m surprised it only takes another 10,000 numbers in each zipcode to do that.

The USPS.com website used to have a ZIP+4 lookup tool that showed the address range of a particular ZIP+4 number (electronic version of the giant books you could find at the post office), but they have seemed to removed that.

I’m also a little surprised that entering a valid ZIP+4 code into the Google search bar doesn’t return an address (or a range of addresses).

The largest zip code in the U.S. only has 144,000 people and the vast majority of them have a fraction of that. 10,000 additional numbers means that you still get 1 unique code for every 14 people or just a few houses if they are properly distributed. In many zip codes, you could have one or more +4 codes for each person in that zip code if you wanted to.

putting mine in gave me a like to the website linked to by hende with my information into giving the range of addresses.

By putting mine in I got a handful of real estate links and a bunch of a junk sites. But I discovered a neighbor up the street has a Cessna. Good to know.

No, not necessarily. If it is large apartment building, yes, but otherwise no.

Pretty cool! I tried that with my Zip+4, and it says “880 to 998 (Even only) MY STREET NAME”. I do in fact live in that range.

And I don’t think they are actually finding ranges. They are just finding the exact address and then defining a range that contains it. The reason I say so is that I live in a place where the numbers are not street based, but distance based. There is no other house within the range given–the houses next door has a number 100 more or less.

I also used to think that the +4 was unique to an address but after getting the occasional misdeliver intended for my neighbors, I concluded it was a range of addresses.

It CAN’T be unique to the address. many ZIP codes contain more than 10,000 addresses. Perhaps even yours. This site will tell you how many residences are in a zip code, and even how many of them are single family homes:

Mine has 11,000 single family homes in it, and that doesn’t even count apartment buildings and commercial addresses.

Wow. It got my apartment complex AND the specific 4-unit building our apartment is in.
