ON the iphone 4 and iphone 5 series go to info on the number and there is an option to block the call now wiht I0s7

I received 2 calls today from 303 and didn't answer. No message was left. After reading some of the other posts, it sounds like they are verifying phone numbers as being valid, and/or matching names to numbers. The work at home thing is just a front, as most people would not be interested in such a potential scam and will say no or hang up, and then the caller knows it's a valid phone number. That's why I never answer calls from obviously impossible numbers. A real company would have a real number.

government agency..

I get calls from this number 2-3 times daily for several weeks. Occasionally, I do answer but no one is ever on the line.

They called a few days ago but it hung up when I answered. Answered today- it was a political survey asking about who I would vote for and what I thought about the debate

Got a call from them today- it was a guy conducted a survey about the presidential election. Just asked who I would vote for and whether or not I watched the debate.

no one speaks, called three times just this past hour

Phone rang - it hung-up after saying hello

Called 2 times, at the moment, this evening, said hello, few seconds later it hangs-up

This number keeps calling

Just tried to add 303-000-0000 into my Comcast "block" list - and it tells me it's an invalid number?! WTF?! If it's 'invalid' why are you patching it thru then??

All VOIP numbers should either be banned, or require a passport and credit check to get... "MagicJack" has fueled these scams beyond control -

If you or I placed 8 PAGES worth of calls in 10 days, they'd haul US off to jail within hours... Welcome to f'n Germany!

I have received a number of calls from this number in the last two days, but when I answer they hang up.

Calls mentioned (13) were received Aug 31st.

Received 13 calls starting in  early evening continued until 8pm.  Did not answer and there was no msg.

Getting several calls per day from 303-000-0000.  I am on do not call list.  No one on other end od call.  Very annoying

Like Lydia, I have blocked this number after multiple calls.  They called me 11 times yesterday, alone.  Yes, it's blocked; however, it still rings once.  I find that to be harassment.  I know, I know, good luck finding them.  But why would you keep calling when you know I'm not interested and continuous calls will only turn me off more.  What have you gained?

I just got a call from this number. He asked for me specifically with my legal 1st name and when I said she wasn't home and could I take a message he just hung up!!!

I am in nv and get 3-6 calls a day.  My dear husband found a way to block them on our home phone.  The number still rings once then is blocked from ringing twice.  Tonight they called  every 5 minutes for about an hour and finally gave up.   It is beyond annoying.

It is a political survey.  They called over and over.  We picked up and they hung up, then called again within a few minutes.

They have called over and over.  My husband picked up and they hung up.  Soon they called again.  This time they were on line:  It is some political survey.

received 9 (that's right...9) of these calls today.  not happy at all.  I have this number blocked but it will ring one time,  it is very annoying.  last call received was at 8:15 pm.

303-000-0000 keeps calling 4 times a day for a week now.  They do not leave a message

This # has called us 4 times.per day for about a week now. We do not pick up

Just got cid & this number has called 4 times in the last 2 days.  Never leaves a message.  Very annoying!

Call from 303 only.  Checked voicemail for the "message" - it was dead air then a click.

I've had 3 calls from this number this evening. I did not answer. There was a lot of noise on my answering machine but no message. They called every hour for three hours. Very annoying! I said "Unknown" for caller and the number was 303-000-0000.

Don't you still get charged minutes?

look closely at your phone bill and see if someone is calling a phone number on your bill. I am getting that same number calling my house and then they call new york on my line. I have a new york number on my phone bill and I never call new york. 17 times..They are using my line to call new york. so in other words, 3030000000 calls my line, then it goes to new york. I called the phone company and they are putting  a stop to it...

Sorry ... I meant to say that I told her to remove my number.

Called today at 2:36 pm CST.  They asked for me by name.  My number is an non-published land line.  She said she was conducting a "political survey."  I told her not to remove my number and promptly hung up.
