Web Form Design: ZIP Codes & Locations

Are zip codes needed for shipping and geo-location? ...

"People need to parse every question a Web form asks them, formulate their response to that question then enter their response into the space the form has provided. The best way to speed up that process -of course- is to not ask the question at all.

For example, if you want to provide geo-location targeted information to customers of your Web site in the United States, chances are you only need their ZIP code and not their full mailing address. That’s four less questions people need to answer: Address line one and two, city, and state.

However, when you actually need to ship an item to someone a ZIP code by itself won’t suffice. Although many retailers in the US use directories to retrieve home addresses when they have only a ZIP code and credit card number, I’ve never seen an e-commerce checkout form that uses this method. So removing the address fields won’t work. Instead, you might want to consider how the question is being asked or how people are prompted to provide a response.

On the Weber checkout form, people are asked for their ZIP code first and then given a set of choices for their city and state. (Thanks to Victor for sending in this example.)"    (Continued via Functioning Form)    [Usability Resources]
