Anyone know why Adsense needs our phone number? Has anyone been called by them? I'm wondering because I'm rather finicky about giving it out. Thanks.
One of the most important rules of business is "Know thy customer." I have never been called and I've never heard of anyone getting called, but whenever money is exchanged, it's customary in business to exchange contact information. Further, Google is most likely using this information for various reasons other than calling people.
Premium is kind of outdated now... they have many more programs when you are ready they will contact you about.
