In China, that would be the unluckiest phone number ever. My 30 story Beijing apartment building lacked floors 4, 14, and 24 due to superstition about 4 meaning death.
That sounds absurd. I can't believe a civilized society would exclude so many floors! In the US where we are completely reasonable and rational we only exclude the 13th floor. I used to work on the "14th floor" (actually floor 13) and I thought this was hilarious.
It might also be a trick on the building owner to make their building look taller. They also exclude the 13th, so that’s a total of 4 floors excluded, but it is only 30 stories, so they get to exclude 34 as well so the top floor is 35.
I feel like if I was superstitious about floor numbers I'd still not want to live on the 4th/14th/24th floor regardless of what they called it. It's still the 4th/14th/24th floor.
Apparently it's pretty common for tall buildings in NYC to skip a few floors so that the top floors have higher numbers. I was grateful for this when my friend's building's power was out and I had to take the stairs to the 42nd floor.
