RE: US Zip codes

["Walden H. Leverich III" <WaldenL@xxxxxxxxxxxxxxx>]

John,

Careful, the Zip Code Tabulation Area (ZCTA) is not a dead match for Zip
codes. They are close now (but not perfect) and I expect that as time goes
on they'll separate even more. Also note, ZCTAs are for census purposes so
they leave out many business-specific zip codes (zips for large entities)
whereas those zips are likely to appear in Booth's case since he's looking
at sales. 

See: http://www.census.gov/geo/ZCTA/zcta.html
And: http://www.census.gov/geo/ZCTA/zctafaq.html
