What is in this dataset
This is a free starter snapshot of 2,000 US ZIP codes, ranked by population so the first rows you see cover the major metros. Each row has 8 fields:
- zip – 5-digit ZIP code
- city – primary city name
- state – 2-letter state code
- county – county name
- timezone – IANA timezone (e.g. America/Chicago)
- area_code – telephone area codes serving the ZIP (slash-separated where overlays exist)
- latitude / longitude – ZIP centroid coordinates in decimal degrees
Source: compiled from curated-us-zips by ReadyAPIs (CC BY 4.0, May 2026 vintage, built from public sources including the US Census Bureau and GeoNames), with telephone area codes from the open-source zipcodes Python package. Coverage: top 2,000 ZIP codes by population across all 50 states, the District of Columbia, and Puerto Rico.
Frequently asked questions
What exactly am I downloading?
A single comma-separated file, us-zip-codes.csv, with 2,000 rows and 8 columns: zip, city, state, county, timezone, area_code, latitude, longitude. It opens directly in Excel, Google Sheets, or any database tool.
Can I use this data commercially?
The base geography is published under CC BY 4.0, which permits commercial use with attribution to the source. Area codes are factual telephone numbering data. This page is not legal advice; check the linked source licenses for your specific use case.
Why does the area_code column sometimes list several codes?
Many metro areas use overlay area codes, so one ZIP can be served by several codes. They are listed slash-separated (for example 212/332/347/646/718/917/929 for 10001). A single-code ZIP shows just one value.
How current is the data?
The underlying compilation is the May 2026 vintage of curated-us-zips. ZIP codes change slowly, but the USPS is the authoritative source if you need guaranteed up-to-the-day accuracy for production address validation.
