Addressr

What Addressr is

Addressr provides Australian address search, validation, and autocomplete through an API or self-hosted software. It uses the Geocoded National Address File (G-NAF), which its maker describes as Australia's authoritative address database with more than 15 million addresses. Search covers addresses, localities, postcodes, and states or territories. Results include a stable address identifier, while an address-detail endpoint returns structured fields and available geocoding. Teams can use a hosted API through RapidAPI or run the software on their own infrastructure. RapidAPI handles hosted signup, API keys, billing, and plan changes; it is also where the maker directs users for current hosted prices and request limits. Self-hosting requires Node.js 22 or newer and OpenSearch, and the first full data download and index takes about an hour depending on the machine and options. G-NAF is released every three months, and the maker recommends scheduling updates to a self-hosted index. Optional latitude and longitude geocoding for self-hosting requires more memory and increases indexing time. The self-hosted software is free under Apache-2.0, but the team supplies infrastructure, hosting, monitoring, and data updates.
