this number is used by yahoo to call people on their accounts for solicitation making money off your account with yahoo. I have saved all the numbers on a magic jack listing them as robocalls and this number comes up a lot for different companies. I went in my yahoo account and changed my phone number twenty minutes later that magic jack number rang with the same sales pitch. If you have yahoo as your mailing address you will get a lot of calls, they are selling your phone number under the associated business clause you agree to so they are not breaking the law.
