I want to see if someone has an unlisted number.

He would have ways of finding even an unlisted number.

It costs $2.50 per month to have an unlisted number.

This winter, he would do well to have his number unlisted.

He said, "Call me with the unlisted number when you get the phone."

I would have loved an unlisted number but it was not possible.

She decided to call the telephone company business office first thing in the morning and ask for a new, unlisted number.

Some cast members did not return calls and several have unlisted numbers.

He switched to an unlisted number but within a short time the calls began again.

And, unlike an unlisted number, I could change it at will.
