Sorry to ruin your day but the national immunization survey is exempt from the national do not call list do to the fact it is a federal government agency the CDC can call you anytime it is a federal agency sorry for the bad news.
Got a call on my cell phone from this number yesterday, no message. All the information provided by others is very helpful; makes me wish I could reach through my phone and throttle the caller.
I have received at least 3 phone calls at different times (once even on a Sunday afternoon). I googled the phone number and found this page. I am so thankful.
They called my cell phone. I called them back (*67 from my land line) and I got "the number you have dialed is out of service"
Received a call from 312759-5263 at 848 pm lastnight on my cell. I did not answer, they left no message. We';ll see if it happens again. Good to see this website has info on this crap.
Keep getting calls from this number in the evening, very annoying! Called back and it said it was toll free hot line for a national childrens center? Wish I could put a stop to this!
