Time is running out to get your cell phone number included on the new No Call list.

The list goes into effect in October, but the deadline to sign up is the end of August.

To sign up, you can call the number on your screen, it's 866-9-NO-CALL, or 866-966-2255.

The number is free, and you can call anytime -- 24-hours a day, seven days a week.
