MBASE is set of functions for reading the MAILBASE.CSZ file.
The MAILBASE.CSZ file is an optimally compressed file that
contains all City, State, and Zip Codes currently recognized
by the United States Postal Service. This data is cross-
referenced in several ways to allow a developer to create an
interactive enviroment that makes data entry faster and more
accurate. The functions provided simplify the development
of this environment, since all file handling, indexing,
filtering, and searching is built in. Additionally, the
MAILBASE.CSZ file stands alone. There are no other files
used or created, making the application more transportable
since the MAILBASE.CSZ file is only about 800K (compare this
to using DBF's and NTX's which would require 5 to 10 times
as much disk space).
The data contained in MAILBASE.CSZ is much more in depth
than merely the City, State, and Zip Codes. Each data type,
is assigned a TYPE CODE which the developer can interpret
for further cross referencing. The city names included not
only have the USPS recognized preferred names, but also
approved abbreviations and local community names comprising
over 80,000 city names. The type codes for the city will
tell the delevoper if an alternate name is available or
preferred and if an abbreviation exists. (All approved
city names longer than 13 characters have a corresponding
approved abbreviation). States are categorized by US state,
territory, or Military PO. Zip codes are identified as
general/residential, PO Boxes Only, Unique to a single
company or government office, or APO/FPO.
The MAILBASE.CSZ file contains the most current
information available from the United States Postal
Service. Updates are available the second month of
each quarter, (FEBRUARY, MAY, JULY, & NOVEMBER).
