libpostal

About

libpostal is a C library for parsing and normalizing street addresses around the world using statistical NLP and open geodata. It can parse an address into components and generate normalized variants, making it a preprocessing layer for search, matching, and geocoding systems rather than a geocoder itself. Official bindings are available for Python, Ruby, Go, Java, PHP, and Node.js.

Features

• Parses addresses into labeled components
• Normalizes addresses across 60+ languages
