>Have you ever wondered how junk mail follows you so easily when you move to a new address? How do credit card companies, catalogs, charities seeking money and everyone else all know when you have moved across town or across the country entirely?

>Whenever you fill out a change of address form with the United States Postal Service, the USPS adds your new details into a database of 160 million previous address changes over the past four years. The USPS has deals with data brokers to sell this data to anyone who pays, provided they have your old address. That means data firms cannot buy the address of Leroy Jones in Cincinnati, but can obtain his new address if they know where he used to live, which they usually do anyway.

And the USPS has a very poor history of safeguarding consumers data.

>The US Postal Service says it’s fixed a security weakness on usps.com that let anyone see the personal account info of its users, including usernames and street addresses. The open vulnerability was reportedly identified over a year ago by an independent researcher but USPS never patched it until this week, when Krebs on Security flagged the issue.

>The vulnerability included all 60 million user accounts on the website. It was caused by an authentication weakness in the site’s application programming interface (API) that allowed anyone to access a USPS database offered to businesses and advertisers to track user data and packages.

Yup. And so does the United States Postal Service. As soon as you hand over the change of address form they sell that info to data collectors. EVERY large organization and company sells your data. Don't even get me started on those "Loyalty Rewards" cards from the grocery store and Target. They are a goldmine to data brokers. Remember when you got to college and you started getting all those credit card applications? Yeah, the schools sold you out. On and on...
