I think we can simplify this with one slider that covers the entire range of post codes: 00000 - 99999
With no detents.
Postcodes are letter letter number number space number number letter letter
Ah, I’m thinking US ZIP Code
What about our Canadian brothers and their codes?? F4S6D4 😂
Easy, 36-base slider with 6 place holders. All potential post codes between 000000 and ZZZZZZ.
You could add a scroll wheel on the screen that you drag to scroll, and let the user set the gear ratio via a similar mechanism.

Put all of the postcodes in a paginated list that displays only 30 entries at a time (60 and 100 per page for premium users), only has next/previous navigation buttons, orders the entries by popularity, and goes back to the first page if you reload the website. Or an infinitely scrolling page that loads each page dynamically, but returns 429 Too Many Requests if the user scrolls too fast.
I reckon someone should try that
Map the tonal range of the human voice from 00000, the lowest-pitched, to 99999, the highest-pitched. Sing a note into your microphone that corresponds to your postal code.
EDIT: Make it a Base-36 range so as to allow letters A-Z when they are used in postal codes.
I don’t care what the particular number is, but it’s a dart throwing game and you have to get all the numbers correct in one shot or start over
Yeah that part I was particularly proud of… It’s so unusable
I remember when r/ProgrammerHumor was full of hilariously bad UX/UI. There were so many amazing entries.
I’ve made a community for it cause I wanna see more of it
In all fairness, it’s not like an address is a well-defined thing in the first place; this form could be made better by eg adding a very small non-clickable preview map where you can manually enter coordinates, preferably in a large font of course.
