I gave solution that has worked for me, family and colleagues. The information provided (like the ID number)is already in these marketers hands, how do you think they can compare it do the list?
Caring suspended, do what you want with the marketing calls.
I wasn't criticising you, merely stating that they are asking for more info than they need to. That coupled with their spotty security history it should give anyone pause about giving them any important personal information. Besides the only time you can be certain these marketers have your ID number is when you submit it to this service.
