Phone Janitor – Take control of your phone number
This sounds crazy, but I'd have a small worry that giving out your CEO's personal phone number exposes potential attacks against other services that use the phone number as a token. Like:<p>(1) Do you have a store-loyalty program at CVS? Can I use your number when I buy stuff and get your coupons?<p>(2) Can I re-set your Amazon.com password using live chat with customer support by convincing them that I know your name and phone number and must therefore be you? Or can I at least have some of your recent orders declared missing and re-delivered to my house?<p>(3) Can I use your phone number in spoof caller ID then call an airline who auto-recognizes the incoming phone number and reveals info about the traveler's flights?<p>(4) Can I reorder prescriptions or learn about prescription drugs using your name and phone number?<p>Just some thoughts. Because a personal phone number is often not common knowledge outside of one's friends and acquaintances, third parties sometimes give it unreasonable importance.
