# address

A physical location, described down to the components a postal system and a legal description each need.

<!--source:mortgage-registry-->
An address describes a physical location described in terms of street address, city, state, region, province, country and other geo-location references.
<!--/source-->

## Why it matters

The widest class in the model, because an address has to satisfy several consumers at once: postal delivery, legal description, geocoding, and the jurisdiction lookups that tax and title depend on.

Components are separate properties rather than lines of text. A line is enough to print a letter and not enough to match two records, and matching is the operation that actually gets performed.
