ClicktoFax Free Fax and Voice Spammer Database
ClicktoFax has been collecting and blacklisting the phone numbers of fax spammers and voice spam callers since our founding in 2004.
We decided in 2012 to release this information to the public in an attempt to combat rampant fax and phone call spamming. Our intent is that other fax providers and businesses can implement this list in their phone systems or switching platforms to help prevent unwanted calls and faxes.
We will update our publicly available fax and voice spammer database each month with new numbers that we detect as potential fax or voice spammers. Please check back each month to get the updated list.
