800-377-5571

I'v done the same thing, I saved all the faxes they sent to us and would fax them all back to them adding new ones each time.

Received this fax today, also like everyone posted here researching this.
while looking through the blogs saw one that is pretty interesting from Jim M 10 Feb 2009. looks like he's had some experience with faxes and explained the reason behind this one. So I need not research anymore and i might just send a fax to them removing us from their list along with a statement of unauthorized faxes. They already have our fax number anyway!

Received a fax from NNRAA claiming to be a "nonprofit corporation whose purpose is to assist recipients of unsolicited facsimile advertisements..."  I believe they've changed their number (since the last comments here) to 866-788-5202.  I've googled and found that on some instances, people/businesses begin receiving MORE unsolicited faxes after faxing NNRAA their unsolicted facsimiles with their own fax numbers included (as specified by NNRAA's fax).  I've filed a report through the FCC online, others might consider doing the same, although they're not advertising or marketing and goods or products so I'm not sure what the FCC could do about it.

What I like to do is save the faxes and when I get a fax from someone with an 800 fax number I send the all the faxes I gather with a note saying I'm not interested in your products, but perhasps you can use one of these other offers.

I received the same fax and its quite annoying try to get rid of these people using my paper source. NNRAA - # 800.377.5571.  And these knuckle-heads @ Corp. Travel # 800.593.5362.

The keep calling my phone over and over again daily..Who are these people?
