Do you need a secret phone number? One that rings but is never answered?

In my book How to be Invisible I listed some numbers that would ring but were never answered. Currently, however, they no longer work.

It was of interest to me, then, when an anonymous reader sent a post to my Q&C page that listed the article, “10 Fascinating Facts About Phone Numbers.”

The most interesting item was that Universal Studios owns the number 212-664-7665—a number that rings but is never answered.

On some of my business cards I list a number in Spain’s Canary islands that rings but is never answered. Unlike the number from Universal Studios, however, I do not offer it free. It is the actual telephone number for a friend of mine on Lanzarote Island and I pay him for his time and for the phone bill. However, the price is very low, so if this may be of interest to you, send me an e-mail. It’s listed on my contacts page.
