pyzipcode
query zip codes and location data
Decision gist · record as of 2026-08-14
No. The package is abandoned (last update 2021-03-03), has high install friction (source-only distribution), and relies on a ZIP code database from 2004 that is now significantly outdated. For current applications, use a maintained alternative or a live API service that reflects current postal code assignments.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.6+; source distribution may require a C compiler or build tools to install.
- High install friction: the package ships as a source distribution only and requires compilation or build steps.
- Maintenance is abandoned—last release was 2021-03-03, over 1990 days ago, with no recent commits.

What it is and what it does
pyzipcode wraps a local SQLite database of US ZIP codes to provide fast, offline lookups of postal code metadata. It loads city, state, latitude, longitude, timezone, and daylight savings time information for any ZIP code, and supports search by city name and radius-based filtering around a given ZIP code.
The package exposes a dictionary-like ZipCodeDatabase interface: you can look up a ZIP code by integer or string, search for all codes in a city using SQL wildcards, or find codes within a specified radius. It requires no external API calls or network access, making it suitable for applications that need reliable ZIP code data without external dependencies.
Use it for
- Validate and enrich user-submitted ZIP codes with city/state information in web forms or data pipelines
- Find nearby ZIP codes for location-based features like store locators or delivery radius calculations
- Populate timezone and daylight savings time data for scheduling or time-aware applications
- Offline geocoding: convert ZIP codes to approximate latitude/longitude for mapping or distance calculations
- Bulk lookup of ZIP code metadata in batch processing without rate limits or API costs
