I checked a dozen phone numbers, and the names of the people were all wrong. Also, notice how none of the names are company names, only individuals. The city names are accurate, though. I can't imagine what the purpose of this site is, except to harvest phone numbers from you to sell to telemarketers. One way to avoid entering your actual number is to type the first 6 digits into the address bar, then when it loads the page, use the "find" function (Control+F) to look for your last 4 digits.
