Recently, one of our clients approached us with the customization request to keep the county information up to date on his contacts in Vtiger. What we came up with was a module that will check the zip code inputted and will automatically update the county field in Vtiger. The way it works is when contacts are: Imported, Created, Hover Edit, or when in Full Edit mode, the county will update. This little feature will help your contacts in Vtiger be up to date whether you are just creating new ones, or edit existing contacts, you will have everything that is needed without having to worry about it.
