Circle is measured from where you first press; Lasso follows your outline. The switch under Add and Remove decides which ZIPs count: Touching (any ZIP the shape touches), Center in (the ZIP's center point is inside) or Fully in (the whole ZIP is inside). For an exact distance, type a ZIP above and press Radius.
To leave out PO Box or single-organization ZIPs (a company, university or government office), or to keep only those, uncheck the others under ZIP types in the list panel.
The dotted grip on each box moves it: click or tap the grip to fold the box away, drag it to put the box somewhere else.
About ZipZoomer: what it does, the data it uses, and answers to common questions.
ZipZoomer’s radius map finds every ZIP code within a set distance of any U.S. ZIP code and gives you the list to copy or download. Type a ZIP code and a distance up to 200 miles, and the map draws the circle and highlights each ZIP code it takes before anything is added.
The map above opens on an example: a 10-mile circle around 60601 in downtown Chicago. Type your own ZIP code in the search box to start from there. It works on phones, tablets and computers.
A ZIP code is an area, not a point, so a circle often cuts through one. The edge rule decides which of those ZIP codes count. The diagram shows the same circle over a grid of square ZIP codes, each with its center dot.
Many radius tools keep one point per ZIP code and include a ZIP code only if that point is within the distance. A large ZIP code centered 12 miles away can still reach within 3 miles of you, and that list leaves it out. ZipZoomer checks the circle against each ZIP code’s real outline, so you see those ZIP codes and decide.
A 10-mile radius around 60601 in Chicago takes 81 ZIP codes by center point and 93 by Touching. Around 82801 in Sheridan, Wyoming, the center-point count is 1 (Sheridan’s own ZIP code) and Touching finds 6, because the ZIP codes around it are large.
Distances are straight-line, as the crow flies, from the ZIP code’s center point (where its number sits on the map), not driving distance. Decimals such as 7.5 work, and the mi/km switch changes the unit. The largest radius is 200 miles (322 kilometers); the card says so if you type more. A circle that crosses a state line takes ZIP codes from both states.
ZipZoomer holds 41,063 ZIP codes in the 50 states, Washington, DC and Puerto Rico. Of these, 33,791 have outlines from the 2020 Census ZIP Code Tabulation Areas (close to USPS delivery areas, not official borders). The other 7,272, mostly PO Box and single-organization ZIP codes, have no outline and show as dots. A radius takes a dot when the dot lies within the distance, under every edge rule.
In a straight line from the center point of the ZIP code you searched, the spot where its number sits on the map. It is not driving distance. ZIP codes shown as dots are measured to the dot.
With the Touching rule, a 10-mile radius takes 331 ZIP codes around 10001 in New York, 200 around 90012 in Los Angeles and 93 around 60601 in Chicago. In rural county seats it takes 8 around 67901 in Liberal, Kansas, 7 around 69361 in Scottsbluff, Nebraska, and just 1 around 59301 in Miles City, Montana, whose own ZIP code covers more than the whole circle. Counts include PO Box and single-organization ZIP codes (map data, October 26, 2026).
