) -- Herman Cain's campaign informed people that any questions about the "9-9-9" plan should be texted to the number 90210, which is the same as the famous zip code for Beverly Hills, Calif.

"Want information about the #999 Plan? Text Cain999 to 90210! Pls RT and share with your friends #tcot," Cain tweeted to his Twitter account on Wednesday.

The text code was used in the title of popular 1990s television series "Beverly Hills, 90210" that aired on Fox and starred actor Luke Perry.

A text message to the number had not received a response at the time this article was published, and the Cain campaign had not responded to an inquiry about how they chose "90210" for texts about the "9-9-9" plan.
