Same thing happened in the USA with 867-5309/Jenny.

Online, I believe that one bit of Beverley Hills has the highest number of online users in the USA.
I am one.
I have never visited California or the West Coast of the USA in my life.
But I have used dozens of websites which need a Zip code.
I have never had a Zip code. I have postcodes, like my old one IM2 3EW. That has letters. It won't fit a Zip code field.
So I and millions of others use the only Zip code we know:
Beverley Hills 90210.
Unfortunately, that was a real phone number in many cities, you could dial the short/local number directly without a 0 and the area code back then. Cue prank calls across the country and quite a few scandals since the topic of the song was, after all, the sex trade.
