The postcode doesn't tell the whole story. But what you can do is use an IP geolocation service which should narrow down your location enough, so that typing in the entire address is no longer necessary.

I.e. using something like https://ipinfo.io/json and then typing in a full postcode and street name + number should work well in most cases.

IP geolocation is increasingly not useful for anything, especially for mobile users. The best it can do is give you the correct country and maybe get you in the right region.

That link nailed me perfectly. I'm on my phone. Connected to wifi, like most people probably are. Chilling in bed or on the toilet.

If you're on cell service.. yeah probably less accurate. Not sure if it makes the form harder to fill out if you have to change some of the fields.

What I've started doing for my personal app though is I've added a "guess" button. It fills in the form using heuristics but it's opt in. Fills out like 10 fields automatically and I've tuned it so it's usually right, and when it isn't correcting a few is still quicker.

I work for IPinfo. The accuracy you see is inferred data actually. Our IP address location should not perfectly pinpoint anyone, unless that IP address is a data center of some sort. The highest accuracy for a non-data center IP address is usually at the ZIP code level. In terms of carrier IP addresses, currently we do one data update per day. If we did more, I guess the accuracy of mobile IP addresses would improve, but on an overall scale, it would be quite miniscule.

Our country-level data (which is free) is 10-15 times larger than the free/paid country-level data out there. We constantly hear that the size of the database is an issue. The size is a consequence of accuracy in the first place. So, it is a balancing act.

By perfectly, I meant it got my city and zip correct, but I looked up the lat/lng and its a 5 min drive away. So pretty dang close!

Not sure how you got it that close if its only supposed to point to the nearest data center.

I work for IPinfo. Has our data been inconsistent for you? We actually invest heavily and continuously in data accuracy. I think for hosting IP addresses we are nearing the highest level of accuracy possible, especially with data center addresses. We are investing in novel, cutting-edge research for carrier IP geolocation.

I am curious about your experience with us so far.

What if I order something on the road and want it delivered to my home? Or what if I want to order something over mobile? My mobile IP is often 1500km away from where I live.

Autofill solves all of that with an implementation cost that approaches zero.
