I can't be the first person to ask for this... most online stores do this automatically. When you enter in your zip code, it automatically fills in the city, state and country fields. Has anybody done this yet, or is there a plugin for this?
I found something called ziptastic that looks like it could be used for this purpose, but it appears to be somewhat of a stretch technically. https://css-tricks.com/using-ziptastic/
I'm just wondering if anybody's done this yet.
it is just code in the address form but the thing you post is 4 years old and https://zip.elevenbasetwo.com/ doesn't even exist as a domain
first find a reliable zip to address service..
I do a similar thing here for Australian suburbs (required by a shipper)
http://www.gjcwebdesign.com/vm2t2/user/editaddresscartBT try any 4 number postcode - e.g. 2000
There is this one for VM2 - don't know if it has been updated for VM3. https://craftyclicks.co.uk/plugins/download-info/virtuemart/

That is for UK postal codes only - I have a version that works for VM3 and J3.5 - But it will not work for any other regions as it uses the PAF lookup that craftyclicks own
You also have to pay a tiny amount per lookup - which IMHO is worth it for correct postal addresses and positive customer experience during checkout
