Coming Soon, Web Ads Tailored To Your Zip+4
On the heels of Apple's intention to collect and sell detailed location data comes word that Juniper is putting together technology that will allow any ISP to present you to advertisers by your Zip+4. An anonymous reader sends this snip from Wired: "Your Internet service provider knows where you live, and soon, it will have a way to sell your zip code to advertisers so they can target ads by neighborhood. If your local pizza joint wants to find you, they will have a new way to do that. National advertisers will be able to market directly to neighborhoods with like characteristics across the whole country using demographic data they've been gathering for decades. ... Juniper Networks, which sells routers to ISPs, plans to start selling them add-on technology from digital marketer Feeva that affixes a tag inside the HTTP header, consisting of each user's 'zip+4' — a nine-digit zipcode that offers more accuracy than five-digit codes. Juniper hopes to sell the software to ISPs starting this summer, having announced a partnership with Feeva earlier this year."
Not quite. Zip+4 narrows it down to no more than 100 possibilities, but you need to know the delivery point to get the exact address. The USPS represents every single deliverable address in the country with an eleven digit number. Five digits of zip code, four digits of +4 extension and two digits of delivery point. You can find your delivery point code by using the USPS zip code finder and clicking on "mailing industry information".
There are a few exceptions to this rule of course. Most PO boxes have a unique zip+4 code, so the delivery point is redundant for them.
I want peace on earth and goodwill toward man.
We are the United States Government! We don't do that sort of thing.
