Unless you removed yourself from the Do Not Call list, re-adding your number opens you up to sales calls for 30 days.  Being on the list is permanent once you register your number. You also must understand that only callers attempting to sell you goods or services from companies you do not have a business relationship with are covered.  Since you need to be a day sleeper the best suggestion is to turn off the ringer on your phone and let your answering machine handle calls unless you need to answer important calls while you sleep.  Friends and family should be aware of your schedule and know not to call during your normal sleep times.

I called the number and it tells me it is a Non Profit Organization. So that is great. The DNC won't work. So I called the 800 number and a lady answered and I asked her to remove me from their contact list. Lets see if it works as I would like some freaking sleep. Turning my ringer off is not an option in case there is an emergency and I would like my line open. -_-

Called This number 800.318.6611 and asked to be removed from their calling list.  I will see if it works.

-just got another call from these folks . . . I guess calling their 800 number does not work.

Dial America - Stop calling please.  We are on the DO NOT CALL LIST.  Why do you call?  Please remove our phone number from your robo-calling system.
