This needs work. It's correctly found an address from a land line in place for the last 40 years, but it's seemingly failed every other possible extrapolation of that info.
This is a private house with an old couple, relatives of mine (which is why I tested with it), living in it. If you're going to try and say what the address is and who/how many live there, how on earth is your site getting it so wrong? It would be better not to try and give such info than to do it so badly.
You could have at least compared the address with easily obtainable data from census or electoral info. Or, noted that it's a residential area and street, not zoned commercial. Maybe shouldn't try for any more than simple stuff like that?

Your lookup has even found the name of the phone line lessor. It's a local service... if you've connected it to Google maps like you have, couldn't you have done SOMETHING better than this crazy failure? TWO people live there, not 16.3 thousand. I mean, come on!!

How can I give your site any trust or credibility if it makes such obvious, huge, inexcusable and easily fixed errors?
Thanks anyway but I better do my lookups elsewhere. And don't try and blame telstra, you're the ones offering a service, you are looking up SOME public info, so if you're going to offer info like number of residents, why don't you get it from a proper source? This is inexcusable.

Sorry, can't trust it.
