Answer 2

One area where address lookups have to be performed reliably is for VOIP E911 services. I know companies reliably using the following services for this:

Bandwidth.com 9-1-1 Access API MSAG Address Validation

MSAG = Master Street Address Guide

SmartyStreet US Street Address API

Answer 3

I have used the services of http://www.melissadata.com Their "address object" works very well. Its pricey, yes. But when you consider costs of writing your own solutions, the cost of dirty data in your application, returned mailers - lost sales, and the like - the costs can be justified.

Answer 4

We have had success with Perfect Address.

Their database has all the US street names and street number ranges. Also acts as a pretty decent parser for free-form address fields, if you are lucky enough to have that kind of data.

Answer 5

As seen on reddit:

$address = urlencode('1600 Pennsylvania Avenue, Washington, DC');
$json = json_decode(file_get_contents("http://where.yahooapis.com/geocode?q=$address&flags=J"));
print_r($json);

Answer 6

As mentioned there are many services out there, if you are looking to truly validate the entire address then I highly recommend going with a Web Service type service to ensure that changes can quickly be recognized by your application.

In addition to the services listed above, webservice.net has this US Address Validation service. http://www.webservicex.net/WCF/ServiceDetails.aspx?SID=24
