Geocode addresses that include apartment or unit numbers
Unit and apartment numbers do not need to be stripped out before geocoding an address, and doing so can lose useful information for no benefit.

How address formats differ between countries
The order of a street, a house number, a city, and a postal code is not universal. Getting the format wrong for a given country is one of the most common causes of failed geocoding.
Parse a free-text address field into structured components
Turn one free-text address string into separate street, city, region, and postal code fields using forward geocoding as a side effect of resolving coordinates.
Name transliteration and diacritics in address data
The same street name can be written correctly in several different scripts and spellings. Matching addresses across these variants is a genuine data quality challenge.
Address parsing ambiguity: apartments, units and PO boxes
A single address string can hide several distinct pieces of meaning, and the same abbreviation can mean different things in different countries. Parsing it correctly is harder than it looks.
Countries with no house numbering system
Not every country organizes addresses around a street name and a house number. Several use entirely different schemes, and geocoding has to accommodate that.
