I’ve seen this technique employed effectively on a few websites – I find it curious that it is not used more often. I don’t know how well this method will work internationally, but assume that some of the same efficiencies apply.
The UI & Process
- Type in a 5-character ZIPCODE:
- In the background, a simple lookup engine identifies the appropriate STATE and CITY and populates the appropriate fields in the form.
- If you want to turn the CITY field into a dropdown selector with multiple choices, as well, you could. But simply pre-populating the CITY field with your “best guess” / biggest town will probably be accurate 95+% of the time,
You’ve just filled in 3 postal address fields by entering only 5 characters.
The Zipcode is a fastTrack shortcut to form entry
