Why does the new Kuna school have Meridian address?

A reader asked me the other day why Kuna’s newest school, Silver Trail Elementary has a Meridian address.
It all has to do with ZIP code. For the most part, the Kuna ZIP code ends at Hubbard Road, so anything north of Hubbard has a Meridian ZIP code, thus a Meridian mailing address. The postal service attempted to change the ZIP codes a couple of years ago, but the outcry was so huge from people living in that area, that the Postal Service left the ZIP code alone. Residents north of Hubbard complained that changing their ZIP code to 83634 — thus giving them a Kuna address — would harm their property values. We’re going to see a lot more of this in the future, as the city has annexed a lot of land north of Hubbard Road. We’re going to have more and more people living within the city limits of the city of Kuna with a Meridian mailing address. In fact, the city’s own wastewater treatment plant has a Meridian mailing address.
It’s not terribly uncommon. In fact, some ZIP codes even straddle state lines. There is a Wyoming ZIP code that goes over into Idaho, for example.
