data from census isn't best quality and it will just repeat the errors
from tiger import. tiger roads have already zip codes. there is no
additional value.<br>
in the long term full address data is the way to go. <br>
imports for data from census should be done only locally where mapper
can verify the quality of the data. <br>
for geocoding it's better to use a plain set of tiger data outside of
osm.<br>

<pre wrap="">Hey Mike,
Where did you find the ZIP Code boundaries? They are licensed data from the
USPS and would not have a compatible license for OSM. Or are you refering
to ZCTAs (ZIP Code Tabulation Areas)? ZCTAs are not the same thing as ZIP
codes <a class="moz-txt-link-freetext" href="http://www.census.gov/geo/ZCTA/zcta.html">http://www.census.gov/geo/ZCTA/zcta.html</a>. They are usually the same
but not always, this is because the USPS doesn't even give their ZIP Code
database to the U.S. Census.
According to this Wikipedia article
<a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/ZIP_Code_Tabulation_Area">http://en.wikipedia.org/wiki/ZIP_Code_Tabulation_Area</a> some of them represent
data that doesn't exist in the USPS database anymore.
Not trying to rain on your parade, just want people to be aware that it is
not the same thing.
