Re: US Zip codes

Al is exactly right - there was a logic to it but over time that logic has 
been somewhat corrupted.

One of the better deals in iSeries applications is one supplied by 
Worksright - ZipCity.  For a nice nominal maintenance you can get the 
product with quarterly updates.  The product contains zip code, state, 
longitude, latitude, area code, prefix, and some other data.  For the 
price it is hard to beat.  We've used it for years and have been extremely 
satisfied.

Booth,

You are correct, based on the original design, but then the design got
modified.

The first digit is the region of the country, the next two digits are
either the city for larger cities  (Like Yonkers NY or White Plains NY),
and then the last two digits were split up by counties, or groups of
counties.  This was the original design in about 1960.

A few problems occurred:

1).   New towns cropped up (subdivisions, villages) and in some cases they
got new zip codes, and in other cased they shared.
2).   As larger cities got larger (before the advent of the 9 digit zip
code), additional zip codes were added.  For example, some of the really
large buildings in NYC added after the advent of the zip code program got
their own zip codes.

My suspicion is that this information is not at all proprietary, because
the USPS will deliver a letter w/o a zip code, but they don't like to.  I
suspect that either their is a web site, or you could buy a CD.

It might make a good TAA Tool, ad a companion to DSPARACDE!

Has anyone information concerning USA ZIP Codes and the state?  I have to
group information by state and have valid 5-digit ZIP codes.

Someone told me they believe the first digit is Region (0=northeast, 9 =
far
west) and digit 2 & 3 are the postal center.  Someone else said that 
digits
1 & 2 signify the political division (State, territory, etc.)
