Open Location Code is a library to generate short codes, called "plus codes", that can be used as digital addresses where street addresses don't exist.

## What it is
Open Location Code is a multi-language library that encodes latitude/longitude into short 'Plus Codes' usable as digital street addresses where addresses don't exist. Encoding and decoding work fully offline with no lookup tables or online services.

## Use cases
- generate plus codes from latitude and longitude
- convert a plus code back to coordinates offline
- give addresses to places without street addresses
- shorten a plus code relative to a reference location
- recover a location from a short code and reference point
- validate or parse open location codes

## When to choose
- you need address-like location codes that work offline without data tables
- you want a well-tested, multi-language implementation of the Open Location Code specification
- you're building mapping or delivery apps for regions lacking street addressing

## When to avoid
- you need full geocoding of place names to coordinates (use a geocoding service)
- you need postal addresses or building-level metadata rather than area codes

## Facets
- artifact type: library
- maturity: stable
- function: geospatial, sdk, parser
- domain: developer-tools
- platform: cross-platform, python, go, rust, jvm, cpp, c, ruby
- tags: plus-codes, open-location-code, geocoding, addresses, latitude-longitude, offline, maps, geospatial, javascript
