Interactive United States ZIP code map

Zoom or pan anywhere in the country and ZIP code boundaries fill in for every ZIP in view, including where they cross state and county lines. State and city names appear as you zoom in. Turn on city or county lines when you need them, and leave them off when you just want the ZIPs.

ZIP code lookup by ZIP, city, or county

Enter a five-digit ZIP code or the name of a city, town, or county. You will land on a page that opens with the boundary map for that area, followed by its population, median household income, and median home value, plus the neighboring ZIP codes and the places that share it. Start with 77007 in Houston, Texas to see how a ZIP page is laid out, or open the Houston ZIP code map.

What every ZIP code page shows

Every ZIP code page combines a boundary map with figures from the U.S. Census Bureau's American Community Survey (ACS) five-year estimates through 2023:

  • Population of the ZIP code area
  • Median household income, useful for comparing neighborhoods, sales territories, and markets
  • Median home value for owner-occupied homes
  • Nearby ZIP codes and the cities, townships, and counties the ZIP overlaps

Figures are shown for ZIP Code Tabulation Areas (ZCTAs), the Census Bureau's mapped version of USPS ZIP codes, so a handful of PO-box-only ZIPs have no boundary or data.

ZIP code map FAQ

How do I find the ZIP code for a city or address?

Type the city, town, or county name into the search box and open the result. The page shows every ZIP code in that place on a boundary map, so you can see which ZIP covers a specific street or neighborhood. For an exact street address, USPS's own lookup remains the official source.

What is a ZIP code map?

A ZIP code map draws the boundary of each five-digit ZIP code over a regular map, so you can see where one ZIP ends and the next begins. This site shows those boundaries for the entire United States on one interactive map, with population, income, and home-value data attached to each ZIP.

Are ZIP code boundaries official?

Not exactly. USPS defines ZIP codes as mail delivery routes, not areas, so it publishes no boundary map. The boundaries shown here are ZIP Code Tabulation Areas (ZCTAs) from the U.S. Census Bureau, which approximate each ZIP as a mapped area. They match USPS ZIPs closely for most of the country.

Where do the population and income figures come from?

ZIP headlines come from the U.S. Census Bureau's American Community Survey 2023 five-year estimates for that ZCTA. The survey period is 2019–2023 (vintage 2023). City and county headlines use ACS 2023 place and county tables for that GEOID. Some ZIP pages also show IRS SOI and a directory population count, each labeled. See methodology.

How many ZIP codes are there in the United States?

There are 42,735 ZIP codes on this site across the 50 states, the District of Columbia, and U.S. territories. 30,003 of those are standard geographic ZIPs; the rest serve a post office box section, a unique organization, or a military address. This map shows every ZIP that has a Census ZCTA boundary.

Can I see all ZIP codes within a certain distance of a location?

Yes. The radius tool lets you pick a center point, set a distance in miles, and list every ZIP code inside that circle. It is a quick way to define a delivery zone, sales territory, or local advertising area.

Which ZIP codes have the highest income?

The rankings page sorts every ZIP code by median household income, nationally or within a single state. You can also rank by population. Each ranked ZIP links to its own page and map.

Is the ZIP code map free to use?

Yes. Every map, lookup, and data page on this site is free, with no account required.

Can I look up ZIP codes by county?

Yes. Search the county name or open its state page, then choose the county. The county page maps every ZIP code inside it and lists the cities and townships each ZIP overlaps.
