I received an advertisement from T-Mobile in the mail today where they must have gotten my data from some website that forced me to fill out personal information

    Surely the last 4 digits don’t point to an exact house. I’m fairly certain my zip code has more than 9999 houses. It does seem like it would get you pretty close though.

      Zip+four is only down the the block level, you need 2 more digits (zip+6) to uniquely identify every possible address in the US. That said, a 9 digit barcode is way too close to a full address for most people to be comfortable with sharing online.

      I suppose I grew up semirural, so growing up, my zip plus 4 identified my single house. Good to know that’s not thexactly the case all the time. Still, pretty identifying.
