I genuinely want to know what lead Google to not support Maps offline properly. It’s truly staggering how, even when I do everything I can to say: save this journey, don’t delete the map around it, don’t delete the journey, just passively show me where I am next to it, it will gleefully delete everything. I once met their lead designer (who had just changed to work at another FAANG) and… boy was that not a conversati…
I had a bizarre encounter when working there, also Maps related. I lived in the UK at the time and my post code just didn't exist in Google Maps. I did some digging, and found out that in fact no post codes in the UK had been added in quite some time. Eventually I found out why: There was some lead dev on Maps, who refused to allow new imports of UK post code data because he thought they were "wrong". They were seein…
Further, as mentioned, there is a limited amount of "number" that can be associated with any one postcode (currently 100 for new codes, but some legacy postcodes may have more), so for a long enough street, the postcode will change at some point - for example Chepstow Road, Newport changes from NP182LU to NP182LX at some point. If you have more addresses in a single building than the 100 limit, then the postcode indeed changes within the building.
This is quite useful as the standard way of entering a shipping address is you type your postcode, and then select the exact address from a dropdown, and there's a natural limit on how long you have to scroll to find yours.
