U.S. ZIP Code Areas (Five-Digit) represents five-digit ZIP Code areas 
used by the U.S. Postal Service to deliver mail more effectively. 
The first digit of a five-digit ZIP Code divides the United States into 10 
large groups of states numbered from 0 in the Northeast to 9 in the far 
West. Within these areas, each state is divided into an average of 10 
smaller geographical areas, identified by the second and third digits. 
These digits, in conjunction with the first digit, represent a sectional 
center facility or a mail processing facility area. The fourth and fifth digits 
identify a post office, station, branch or local delivery area.

The polygons identify areas where mail is delivered 
(from a city block or two to a whole rural town) within United States.

U.S. ZIP Code Areas (Five-Digit) provides area, post office name, and 
population for each ZIP Code area in the United States.  The polygons 
identify areas where mail is delivered (from a city block or two to a whole 
rural town) within United States.

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
The following steps were performed by ESRI: 
-Extracted data set from Tele Atlas Dynamap/Census Boundaries v. 7.0.  
-Created region features from the polygon features.  
-Added the SQMI attribute and calculated its values.  
-Added POP2005 attribute from ESRI Community Data.  
-Added attribute POP05_SQMI and calculated its values.  
-Added and calculated SUMBLKPOP attribute by overlaying 
 2006 U.S. Census Block Centroid Populations then summing the 
 Census Block centroids that fall within each ZIP Code area.  
-Converted the data set to SDC.  
-Created ArcGIS layer file (.lyr), projection file (.prj), and spatial indices.
Process Date: 20060413

The GeoPlan Center downloaded the zip code boundary data from the ESRI 9.2 Data and Maps DVD. Reprojected the data from GCS_WGS_1984 to FGDL NAD83 Albers (HPGN). See below for full original metadata. GEOGCS["GCS_WGS_1984", DATUM["D_WGS_1984", SPHEROID["WGS_1984",6378137,298.257223563]], PRIMEM["Greenwich",0], UNIT["Degree",0.0174532925199433]] GeoPlan added the following three zip code boundaries to the dataset. GOODLAND EVERGLADES CITY CHOKOLOSKEE After adding the three extra zip code boundaries the attribute table was then updated for these records. GeoPlan then added the following fields to the dataset.
