90210 is the most famous zip code in America because there was a really popular show in the 90s that referenced that zip code called "Beverly Hills, 90210" (commonly known as just "90210"). It had various spinoffs going into the 2010s. Because that zip code was so famous an unrelated reality show was named "Dr. 90210" about plastic surgeons in the Beverly Hills area.
