The "Zip Code Browser" allows the user to search for zip codes within selected regions, hubs, and routes. IDLS will search for all codes within the search parameters, even if the full zip code is not searched for- if the user searches for "50", he will get results of all zip codes beginning with "50". 



Also within the "Zip Code Browser" are links to pages to "Edit Regions" and "Add New Zip Code". There is an option to import zip codes and regions by following the steps outlined within the application.
