Stop Giving Companies Your Phone Number. Do This Instead.
Facebook and Twitter admit that marketers accessed the phone numbers people gave them for security verification.

In many ways, it may be too late to prevent these big social networks from using your phone number how they see fit. Facebook told me that they will only delete your phone number from their records if you delete your entire account. (And much as I've been tempted to, I've been unable to take that drastic step.) Twitter requires a phone number for 2FA, even if you use an app, although it says that may be changing.
