It’s bad enough I have to report it, but for them to answer, basically, that I made a mistake is just absurd.
Here’s their response:
So, it’s my fault for using the actual name of the street instead of the abbreviation they recognize? Hey “Yahoo Expert”, your help instruction files say otherwise. Please check Help before writing, as you required me to do.
Sheesh
Did you try the complete address in Mapquest or Googlemaps?
These services always come up with errors from time to time. Even Thomas Bros. maps have errors, but those are usually intentional, to fight copyright infringement.
Huh? What did you enter and what result did you receive that was wrong?
Who does that guy think he is? Shodan? 
I gave up on Yahoo maps after reporting several times over a THREE YEAR period that they if you entered the name of the small (population 200) town I used to live in, it would give you directions to the middle of a field ten miles away. They also didn’t recognize my address. Most of the time, they wouldn’t even respond, and the rest of the responses were dismissive “we’ll look at it” messages. As far as I know, it’s still wrong.
To be fair, this is probably not entirely the fault of Yahoo maps. Odds are they, like most mapping services, have incorporated the US Postal Service’s Address Information Systems (AIS) Products. This includes “address standardization” which takes every address which receives mail, and everything we think of as an address is actually a postal address in the US, and has standardized ways of storing them. Avenue becomes Ave, Boulevard becomes Blvd, etc. It’s the underlying database, which pretty much everyone uses, which has these characteristics. Now some other mapping services have written software to recognize words like Avenue, Court, Circle, and translate them into USPS-speak, Ave, Ct, Cir, etc. but it doesn’t look like Yahoo maps has. That’s their fault, but the shortening/standardization of street/postal addresses is largely the doing of the organization which invented them, the USPS.
Enjoy,

I would bet the programmers of Yahoo’s map would love that sort of input. That is data they need. However, I have no doubt some middle manager decided that the yahoos that use their site could never have any useful input, and therefore, locked the programmers in a dark basement and feed them flat foods.
I haven’t looked at a Yahoo map in a while, but Mapquest always looked like a bad cartoon, not a serious way of finding your way.
Our GPS is so utterly, completely and totally wrong on how to get to our house, it is actually rather sad.
I’d try to correct it, but I’m so disappointed in Tomtom overall, I lack the motivation. Our Garmin Nuvi found our house just fine.
Like most thing in this world… the idea was inspiring… the execution was disappointing.
Google Maps… when looking at the street view… has my home 4 houses away to which it actually is. Which is fine… big whoop. However, it makes you wonder what they are thinking when my house is “1234” and the picture clearly states “1238”… and I mean clearly visable. I guess I haven’t really tried yahoo maps and map quest… yeah. I gave up on that long ago… gives you a general idea granted theres no construction… no rush hour… no accidents… et al… yeah.
And as excited as I was to replace Map Quest with my Garmin… theres bugs even in that. But at least it re-calculates if you do happen to need to take an alternative route for whatever reason.
…although I must admit… I turn off her/his stupid voice and rebel against what they advise… buwahaha. OH. Another fun game… put it into a language you aren’t even sure how to pronounce… roll down the windows and turn it up… confuse the heck out of the drivers next to ya… or even the people in your car.
My mother and I took a road trip. We chose to drive at night since we had my 3 year old with us. Our biggest complaint of the GPS was that the damn thing insisted on waking us up. 
I’ve found that Google Maps is generally the best of the bunch when it comes to not messing things up. Well, except for the name of my university (15,000 students, not exactly a hole in the wall) which has always been misspelled.
So far I’ve only contacted Google Maps twice, but they have the hugest roundabout way to get to my neighborhood involving some gravel road over the side of a mountain that I don’t think is even passable anymore. Keep in mind we are right off of US Rt. 60 – no need for crazy roads to get here at all! I mean I know they built a new bridge about 8 years ago that’s a few hundred yards from the old one, but for it to ignore both bridges and have you take that crazy road? The bridge and road are clearly visible in the satellite photos of the area.
My parents’ road is screwed up too, but not so badly that you couldn’t find the house pretty easy.
I should check and see how Yahoo gets us here.
WOW! Yahoo impresses me. It not only has the “new” bridge by my house, but several other new roads that have been built over the past few years. It is exactly right on the route from my house to my parents (about 8 minutes away). Heck it even shows the road that goes around the cemetery!
The only think it does wrong is put our house about halfway up the hill, when we are really the last house.
My uncle lives on a street that connects with another so on a map it looks like the capital letter “L”. My uncle lives on the vertical street, Dog Street, the bottom, horizontal part of the “L” is Cat Street.
On Mapquest, you can type his address, 123 Dog Street, and it will correctly show you his house… but the street is labeled Cat Street. According to Mapquest, the entire “L” is Cat Street. In fact, there is no Dog Street to be found anywhere in his town if you look at the Mapquest map. But if you type a Dog Street address into the search bar, it will still put the little red star in the correct place.
I find that much more confusing. Type in “123 Dog Street” and they show you “123 Cat Street” on the map. But if you try typing in “123 Cat Street” you’ll get an error because the address does not exist (because it really doesn’t exist).
I tried contacting Mapquest, and sent them the link to the actual city’s website with the correct map, but they sent a stupid message back saying they get all their data from some mapping service and if it’s wrong, to contact them.
The same would be true for Yahoo or Google. None of them collect their own map data; they buy it from mapping companies.
This was a number of years ago, but…
I tried to use Mapquest for directions from central Jersey to Derry, NH–that’s in the southeast corner, basically a suburb of Boston.
The route they gave me?
Take 95 up. Past Boston. Through New Hampshire. All the way up the coast of Maine into Canada.
Then get on the ferry to Prince Edward Island.
Then drive 4,500 miles southeast!
I plotted it on a map. Even if I could drive over the Atlantic Ocean, I’d end up in Cameroon.
I tried it again. Same result. I had other people try it from their computers. Same result.
Naturally, I thought this was hilarious, but I figured I’d better let Mapquest know.
I got a standard form letter back with no acknowledgement of the absurdity of the situation or explanation of how such a thing could have occurred. So I emailed again. Another form letter. So I emailed again, specifically asking for a non-form letter response, and an admission that it was funny. And I actually received it. But they didn’t fix the problem for a long time afterward.
Interesting. Google maps shows my uncle’s house correctly both if you type his address and look at the map. Yahoo Maps has the identical error as Mapquest only worse, because it doesn’t recognize my uncle’s address at all. You type in 123 Dog Street and it says there is no such thing. My uncles has lived there longer than I’ve been alive.
Look at the bottom of the map window and you’ll see where the map data comes from, usually.
