Add postal code auto-fill to a shipping form
Let a customer type just a postal code and have city and region fields fill in automatically, cutting a shipping form down by two fields.

#forms
Build a time zone picker that defaults to the visitor's zone
Pre-select a visitor's own time zone in a settings form using their IP address, instead of asking them to search for it themselves.
Restrict form submissions to a delivery radius
Geocode a submitted delivery address and reject it automatically when it falls outside a fixed distance from your hub, before an order is ever placed.
Add a country dropdown that defaults from IP
Pre-select the right country in a signup or checkout dropdown using a visitor's IP address, saving a scroll through a long list without ever removing their choice.
Build a "did you mean" suggestion box with autocomplete
Show a short list of likely matches as someone types an address, so a typo gets corrected quietly before it is ever submitted on the form.
Validate a postal code before you save it
Confirm a postal code actually resolves to a real place before it goes into your database, using a single lookup against the right country code.
Add address autocomplete to a checkout form
Wire up address suggestions as a customer types, cutting down on typos and abandoned checkout forms without a mapping library or extra scripts.
