This algorithm parses the address information provided and extracts ZIP codes from it. Currently it accepts ZIP codes which are in United States of America format i.e. either XXXXX (short form) or XXXXX-XXXX (long form).
Pros & Cons
This algorithm facilitates quick Spatial analysis by extracting ZIP codes from a given address, which can be further processed. Its only limitation is that currently it only supports parsing of USA ZIP Codes or countries which have USA based ZIP Code format.
The algorithm works as follows,
The user has to provide 3 inputs; a file containing the addresses for which ZIP code parsing is required, whether to truncate the parsed ZIP code or not and name of the address column. If the plugin was unable to find any ZIP code then it will print a warning message and set the ZIP code to empty string. The data for ZIP codes can be in either short form i.e. XXXXX or long form i.e. XXXXX-XXXX. It will also accept ZIP code information in the following format,
XXXXX<Any Character(s) of Max Length = 2>XXXX.
The ZIP code extraction algorithm was authored, implemented, integrated and documented by Chintan Tank.
