Why can't I look up my USPS ZIP code in QuickFacts?

QuickFacts does not contain data for Postal ZIP Codes. Only States, Counties, Places, and Minor Civil Divisions ( MCDs ) for Puerto Rico and the United States with populations above 5000. When you search via a ZIP code QuickFacts provides a list of near matches for the geographic types contained within the application. These near matches are created from US Census Bureau ZIP Code Tabulation Areas ( ZCTAs ) which are generalized area representations of United States Postal Service (USPS) ZIP Code service areas.

Why are some cities, towns or zip codes missing in the dropdown menu?

Geographies with populations below 5,000 are not currently shown in QuickFacts. If you don't see the area you are looking for, try checking DATA.CENSUS.GOV .

Where can I get data for other levels of geography, like metropolitan areas?

While not all geography types are available in QuickFacts profiles, there are a number of sources on census.gov .

Value Notes

Methodology differences may exist between data sources, and so estimates from different sources are not comparable.

Some estimates presented here come from sample data, and thus have sampling errors that may render some apparent differences between geographies statistically indistinguishable. Click the Quick Info  icon to the left of each row in TABLE view to learn about sampling error.

The vintage year (e.g., V2024) refers to the final year of the series (2020 thru 2024). Different vintage years of estimates are not comparable.

Users should exercise caution when comparing 2019-2023 ACS 5-year estimates to other ACS estimates. For more information, please visit the 2023 5-year ACS Comparison Guidance page.

(b)Hispanics may be of any race, so also are included in applicable race categories

NData for this geographic area cannot be displayed because the number of sample cases is too small.
