I do write Lisbon, Portugal, whenever I talk about where I live. Doesn't take much extra effort to provide more precision and avoids possible confusions.
In a moment of whimsy I briefly considered a date format where digits were sorted alphabetically.
2026-07-02-16-31-52 -> -----00011222235667
Hopefully it will remain a nonsense and never be seen in the wild, unlike the phone number field which I found on a real website which responded to scroll events to increase and decrease the value it contained.
Well that's just totally ambiguous. What you should do instead is treat the date as one long number and present its factors, for instance 2⁴⋅11⋅7649⋅15050023, much more practical.
Most every personal phone number I've obtained has had a spelling, and a good logical spelling, which isn't really the norm for personal phone numbers.
In fact, the first time I signed up for my own line, it happened unintentionally, and it was only after Pacific Bell had installed the line that I figured out it spelled something, and I informed my father and it was hilarious (the spelling was "BUG-BLOW").
Do you also address your mail to "United Kingdom, Scotland, Edinburgh;" or tell people, "I'm going on holiday to Croatia, Split?"
