What You Will Find Here
Address data enters your systems as raw, unstructured text — OCR output, legacy CSV dumps, web-form submissions. This site documents the engineering discipline required to systematically transform that noise into clean, geocoding-ready records at production scale. Every guide is written for practitioners building real pipelines, not theoretical overviews.
From deterministic regex engines and Unicode NFKC normalization to statistical libpostal models and LLM-assisted parsing, the Core Address Parsing section covers the full spectrum of standardization techniques — including edge cases like PO Boxes, rural routes, military addresses, and international formats across Europe, Asia, and Latin America.
The Multi-API Routing section focuses on resilience: building async Python geocoding clients with
aiohttp and asyncio, implementing circuit-breaker fallback chains, tracking API quota consumption
with Redis, and routing requests intelligently across Google Maps, HERE, Mapbox, and OpenStreetMap based on regional accuracy benchmarks.
Transform unstructured location strings into machine-readable, geocoding-ready records. Covers regex engines, NFKC normalization, USPS CASS compliance, libpostal integration, and handling edge cases from PO Boxes to international formats.
