Falsehoods about address format
The falsehoods
The falsehoods
An address is not necessarily a point on a map. It is not necessarily a polygon. It is not necessarily a discrete building. It is not necessarily at ground level. It is not necessarily the only address at its coordinates. And it is not necessarily stationary.
This article series is inspired by and cites Michael Tandy's excellent, exhaustive original — the canonical catalogue of address falsehoods, maintained since 2013. Tandy's article is a taxonomy of assumptions that break parsers, validators, and databases. This series expands on that taxonomy, adding historical context on how geocoders have handled (or failed to handle) each category, and what Mailwoman's neural approach changes.
The falsehoods
"Close enough" is a statement about your use case, not about the coordinate. A geocode that is correct for statistical aggregation may be catastrophically wrong for emergency dispatch. And the coordinate itself answers a question — "the front door" — that nobody bothered to define.
