Comcast will give out your home address to anyone who asks

I recently noticed what feels like a major privacy flaw in Comcast's automated telephone system. If you call in and select the option to make a payment, then enter a phone number, the system immediately asks you to verify your home address by reading it out to you.

The result is anyone with your phone number can find out exactly where you live by simply knowing your phone number.

Making matters worse, if you then pay the bill on someone else's account, the system prompts you to add yourself as an authorized user and requests the callers phone number, potentially granting them full access to your account.

Maybe Comcast should verify it's you before dumping out your home address, no questions asked, to anyone with your phone number?

To clarify, this was NOT matched with caller ID. The call was made from someone else's, previously unlinked, cell phone into the account.

The account phone number was then manually entered, because the number was unrecognized, by a third party with an unlinked cell number. They were then asked to add the new phone number and authorize themself.

Sounds like too many people have gotten used to their personal information being shared, bought, and sold, all over the place. From a much broader, semi-related perspective, a leaked address may feel insignificant, but its the exact reason we need to push for decentralized technology like crypto currency, IPFS decentralized internet, and stricter privacy laws like we are already seeing in the EU with GDPR
