Addressr
Sydney, New South Wales, Australia
What it is
Addressr provides Australian address validation, search, and autocomplete through an API, with hosted and self-hosted options. It uses the Geocoded National Address File (G-NAF), which its maker describes as Australia’s authoritative address database, containing more than 15 million addresses. Searches can cover addresses, localities, postcodes, and states or territories; results include a stable address identifier, and a separate endpoint returns structured details and available geocoding. For hosted use, RapidAPI manages signup, API keys, billing, and plan changes. The maker directs users there for current prices and request limits. The self-hosted open-source software is listed as free under an Apache-2.0 licence, with no hosted request limit; the team supplies infrastructure, hosting, monitoring, and data updates. Self-hosting requires Node.js 22 or newer and OpenSearch, and the first data download and index takes about an hour depending on the machine and options. Optional latitude and longitude geocoding needs more memory and adds indexing time. G-NAF is released every three months. Addressr also documents an MCP package for several compatible AI assistants.
For and against
For
- Search covers addresses, localities, postcodes, and states or territories.
- Results include a stable address identifier.
- Self-hosted software has no hosted request limit.
- An MCP package is documented for compatible AI assistants.
Against
- Self-hosting requires Node.js 22 or newer and OpenSearch.
- Initial self-hosted download and indexing takes about an hour.
- Optional geocoding needs more memory and increases indexing time.
- The self-hosted default does not enforce proxy authentication.
The verdict
Addressr offers Australian address lookup through a hosted API or self-hosted software, with structured results and optional geocoding. Self-hosting provides data and infrastructure control but requires a team to run and update the service; hosted prices and request limits are listed through RapidAPI.
Who it suits
Addressr suits teams that need Australian address search in an API, including teams that prefer a hosted service and those that need control of their own infrastructure and data updates. Self-hosting is for teams prepared to provide and maintain that infrastructure.
