I called the number back and received an automated recording. The menu will direct you to removing your number from their list. The recording said it can take up to 30 days but would try to remove number from their list within a few days. I will be waiting.

My rule of thumb is if the caller id says "unavailable", then I am unavailable too!

I get calls from them all the time. For over a year now. I've also gotten the call from the real Cancer Research people asking me to send the envelopes to neighbors. They must be two different entities. No idea where the robocalls are coming from, as they always hang up.

AICR is the American Institute of Cancer Research with an aggressive and reportedly impolite fund raising program. As a charity they get a one star out of a possible four star rating. The President and VP command salaries of over $275,000 each. For a direct link to the Charity Navigator report see

This number calls ever day and sometimes at night. Sometimes twice a day. They hang up or never leave anything on the answering machine if I don't pick up. How do I/we get them to stop.

Caller hung up when I answered.
Same thing happened yesterday.
I'm also on Do Not Call lists. Makes me think it's political.

We're on the DO NOT CALL list, also.

Receive 1 call every other day from this number. I do not answer & no message is left.

They call but don't leave a message and it is very annoying. This has been going on for over a week now.

I too have had several calls from this number over the past month, caller ID AICR. I do not answer and am on Do Not Call List. How can they do this and how can they be stopped?

Just got a call from this number American Institue of Cancer Research asking that I ok them sending letters to my neighbors asking for donations on my behalf. Obviously I declined and asked to be removed from the calling list. I am on every "Do Not Call List" I can find, so I am not sure how they are legally soliciting me.
