<p><font size="2">Okay,</font><br>
<br>
<font size="2">I was really just causing trouble with my e-mail. I have a personal bias against distribution fees for what are essentially public data. But having said that. I got some good answers so I thought I would compile them.</font><br>
<br>
<font face="Times New Roman">A good roll your own suggestion from John Sykes (Valerie Milmore had the same idea, but no instructions):</font><br>
<br>
<font face="Times New Roman">See if this works for you. First create a clean shapefile of county boundaries from the Tiger County Boundary layer from the Florida Geographic Data Library (FGDL) at FSU. You need to dissolve this layer, because a couple of the counties have more than one record (notably Bay and Volusia Counties). After dissolving you should have 67 records for the 67 counties. Then, download the USPS zip code layer from the FGDL. Finally, you need to perform a Spatial Join of the two layers. Use the ToolBox Spatial Join NOT the others! Please note that there are more resulting records that in the input zip code files, because many zip codes cross county boundaries. I would send you the resulting Shapefile, but it is too large to e-mail. I almost forgot, it is important to set the buffer to Intersect, NOT Contained, because of this county overlap.</font><br>

<font size="2">From Yurong Tan:</font><br>
<br>
<font size="2" color="#000080" face="Arial">Also, you have to keep in mind that zip codes do not necessarily follow county lines – a zip code can cross city, county and state lines. Also, there are point zips too. </font><br>
<br>
<font size="2">Which brings up a good point. Not all 5 digit zips are polys. Think of the State Agencies. And the zip+4 (9 digit) are even worse, They correspond more closely to a carrier's route. Apparently, the definition of a zipcode (from the Maponics website that Henry sent out) is a set of address points. </font><br>
<br>
<font size="2">As for me, I believe I just used TeleAtlas Dynamap data for what I was doing. However, I can't find the dataset I used because I took it offline, so I can't swear to it actual existence. </font><br>
<br>
<font size="2">And last, but not least. Look on the ESRI Data and Maps Media Kit that shipped with your ArcGIS. It has 3 and 5 digit zipcode shapefiles.</font><br>
