Did you receive a call from unknown caller ID and the caller did not leave any message? Wandering who that was? 800Notes is a free website that can help you identify unlisted phone numbers. Simply enter the caller’s phone number and 800Notes will check if there are other people who received the call from the same number and show their comments. One of the obvious ways to make use of 800Notes would be to identify and report phone spammers.



  • Find and report annoying unlisted (“name unavailable”) phone numbers.
  • Extra: news, articles and videos related to telemarketing and robo-calling.

    800notes is ran by government shills.
    The site has no official contact information which is common practice when the government collects the data.
    The poster known as Celtic Dragon is actually Kerry Chatwin.

    I prefer - it allows you to automatically block telemarketers. And i think the site is better designed.

    I have tested it, but it could not any info for the tested numbers. As I understood it, users can enter info about these numbers themselves.
