ZIP Code Radius Finder

Every ZIP Code within a distance of any ZIP Code, and who lives there.

What the radius shows you

A map and a list

Every ZIP Code in the circle or ring, how far away it is and how much of it is inside, ready to copy or download.

Who lives there

People, households, income, homes, rent, age and commutes for the whole area, from the Census Bureau.

How it has changed

Compare the area with earlier years, in today's dollars.

A radius built on real ZIP Code boundaries

A ZIP Code isn't a shape drawn on a map. It's a set of mail delivery routes, so its truest outline is the area those routes cover. Our radius measures that area.

One point per ZIP Code

Most radius tools check only each ZIP Code's center. A ZIP Code that reaches well into the circle is left out when its center is outside, and one that is barely inside counts in full.

Census ZCTAs

The Census Bureau's ZIP Code Tabulation Areas are built from census blocks, not mail routes, and are redrawn only with each census. Most PO Box and single-business ZIP Codes have none.

Our ZIP Code boundaries

Built from USPS carrier routes, the lines carriers actually deliver along, and rebuilt every quarter. The spatial radius counts each ZIP Code by how much of it is inside the circle, and its people by the same share.
