ZIP codes and ZCTAs

ZIP codes are mail delivery routes, not areas, so the Postal Service doesn’t publish boundaries for them. The Census Bureau builds the closest thing, ZIP Code Tabulation Areas (ZCTAs), from the ZIP codes of the addresses in each census block. They match the mailing ZIP code almost everywhere, and that’s what we show and draw.

Some ZIP codes have no area at all: P.O. boxes, single buildings and big organizations get their own. The example, the Empire State Building, has a ZIP code all to itself (10118), but a one-building ZIP has no ZCTA, so the map shows the area around it: 10001.

From your location or an address

Use your location and we look up the ZCTA you’re standing in. Type an address and we place it on the map first, then do the same. You’ll also get the nearest street address, the city (or “unincorporated”), the county and the state.

Near the edge of a ZIP code area, especially in rural places, the two sides of a road can have different ZIP codes. When it matters, check the address on your mail.

Frequently asked questions

Is a ZCTA the same as a ZIP code?

Almost always. A ZCTA is the Census Bureau’s map of the area served by a ZIP code. P.O. box–only ZIP codes don’t have one.

Why is the ZIP code different from my mail?

ZIP codes can change or be split, and ZCTAs are updated with each census. Your mail’s ZIP code is the one to use for shipping.

Does a ZIP code tell me my city?

Not exactly. The postal city name often covers areas outside city limits. We also show your official city.

Does it work outside the US?

Yes, with the postal code of the nearest address from OpenStreetMap; in Spain, from the official CartoCiudad street map.

Do you store my location?

No. It’s used once for the lookup and never saved.
