</div>None of the Iowa data that I am processing originates with the US<br>
Census or TIGER. The underlying sources of the data are described ad<br>
nauseum here:<br>
<br>
<a href="ftp://ftp.igsb.uiowa.edu/gis_library/counties/Story/Address_85.html" target="_blank">ftp://ftp.igsb.uiowa.edu/gis_library/counties/Story/Address_85.html</a><br>
<br>
Basically the data comes from county auditor parcel data, processed<br>
through the US Postal Service addressing database, and compared<br>
against aerial photography to move the point to the intersection of<br>
the driveway with the road.<br>
<br>
As for name expansion, I'll take a look into that. The data source<br>
that I'm using doesn't separate prefixes and suffixes out like TIGER<br>
does though...<br>

</div>As Richard Welty said, the addr:city tag is pretty much required, as<br>
US addresses aren't defined by the boundaries of the city you live in<br>
(or don't live in for rural addresses), but the post office that<br>
delivers your mail.<br>
<br>
I can see not including the country or the state, do the various<br>
routing/geocoding engines take advantage of state/country polygons?<br>
Are there any exceptions out there where the address is physically in<br>
one state, but their postal address is from a neighboring state<br>
because that's where the post office is?<br>
