Using one of the Fairfax County Zip Codes to find a home by school is like using a plumbing plan to find the electrical main on a house.

Fairfax County Zip Codes are like an architectural plan
When an architect draws plans for a house, there is a specific plan for the plumbing installation, and a different plan for the electric installation.
If we were to put these different plan drawings on top of each other, it’s possible that the electric and plumbing installation share certain paths throughout the home, say, along the same wall. But most likely, each of these installations have enough differences that they each require a drawing of their own.
Just like when building a home, when setting up the infrastructure of a county, there are different plans for dividing the area
- Fairfax County Zip Codes are one plan – used mostly by the United States Postal Service (USPS) to determine mail routes.
- Fairfax County School Boundaries are another plan – determined by the School District to assign homes to schools.
And rarely do these two plans match when placed on top of each other on a map.
For example:
School Pyramids are a way to group schools for administrative purposes.



Everybody is welcome to find a home by school boundary. A school boundary
is simply a geographical area, just like a zip code or a postal city.
