Loading ZIP outlines…
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 is a free map of all 41,063 U.S. ZIP codes for building ZIP code lists: select ZIP codes by clicking, drawing a circle or lasso, or setting a radius around a ZIP code or your location, then copy, download or share the list. It covers the 50 states, Washington, DC and Puerto Rico, and works in any modern browser on computers, tablets and phones, with no sign-up and no ads.
ZipZoomer is made by ThingLab (thinglab.app), a small studio that builds web tools. It went live on October 22, 2026 as a California ZIP map, covered the whole country from October 25, and moved to zipzoomer.app on October 26.
The map data was last rebuilt on October 26, 2026. The outlines change only with a new census; the ZIP list is updated when the zipcodes package is.
Your selected ZIP codes and settings stay in your own browser. “Use my location” uses your position on your device only. Analytics (Google Analytics through Cloudflare, and Cloudflare Web Analytics) count visits and which features are used, never which ZIP codes or what you type. The privacy page has the details.
Questions, corrections to the data, or ideas: write to policies@thinglab.app. If a ZIP code is missing, misplaced or has the wrong city, include the ZIP code and what you expected.
Yes. There is no sign-up, no ads and no usage limit.
They are the Census Bureau’s 2020 ZIP Code Tabulation Areas, the standard public outlines for ZIP codes. USPS does not publish boundaries, so no map can be exact address by address; a few addresses near an edge may use the neighboring ZIP code.
The map data was last rebuilt on October 26, 2026. Outlines change with each census; the ZIP list, types and city names follow the zipcodes package.
Yes. The lists are yours. The underlying Census data is public domain; if you republish the street map itself, keep the OpenStreetMap credit.
