libpostal is a C library for parsing and normalizing street addresses from around the world using statistical NLP and open geo data. It converts free-form address strings into clean, normalized forms suitable for machine comparison, deduplication, and full-text indexing.

Use cases

• parse street addresses into components like house number, street, and city
• normalize address strings for deduplication and record linkage
• preprocess addresses before geocoding
• index addresses in a full-text search engine
• handle international addresses in many languages and formats
• clean up messy user-entered address data

When to choose

• you need to parse or normalize addresses across many countries and languages
• you want a fast C library with bindings for other languages
• you're building geocoding, delivery, or place-search features that need address preprocessing
• you need address deduplication or record linkage at scale

When to avoid

• you need a full geocoder that returns coordinates - libpostal is not a geocoder itself
• you can't accommodate its large trained model data downloads
• you only need simple US-only address parsing with minimal dependencies
• you need a pure high-level-language solution without C compilation
