Addressify

Addressify is a cloud API for Australian address verification and processing in websites, forms, apps, and business systems. It can check and correct address entries, including incomplete details, misspellings, or incorrect postcodes, and can parse free-form text into fields such as building name, unit, street, suburb, state, and postcode. Its autocomplete and geocoding features can return coordinates for an address or identify an address from coordinates; it can also provide a meshblock for integration with ABS sociodemographic data. Addressify uses the Australian government’s G-NAF dataset and says it refreshes data every three months when the government releases new data. The API supports HTTPS and can connect to systems that make HTTP GET calls and handle JSON, including customizable CRM and ERP systems and Microsoft Excel, Access, and Word. A 30-day Trial costs nothing and allows 1,000 daily API calls. Lite costs $2,000 a year, and Pro costs $4,000 a year; prices are GST exclusive. Lite validates street-level fields, while Pro provides complete validation.

Addressify brings address correction, parsing, autocomplete, and geocoding together for Australian data. The key plan distinction is validation depth: Lite covers street-level fields, while Pro provides complete validation.

Addressify may suit organizations that need Australian address processing in their own sites, forms, apps, or business systems. Lite and Pro are for internal organizational use; VAR accounts are intended for software vendors embedding and reselling the service.

Addressify is an API for correcting, validating and enriching Australian address data in websites, forms, apps and business systems. It is best suited to organizations building Australian-only workflows that can make HTTP GET calls and handle JSON. Its broad toolkit is useful, but full validation requires the more expensive Pro plan.

Overview

The service brings address correction, parsing, autocomplete and geocoding into one API. It can separate free-form entries into building, unit, street, suburb, state and postcode fields, correct errors such as misspellings or wrong postcodes, and attach coordinates or a meshblock for ABS sociodemographic data. That range serves both data-entry flows and downstream business systems, though international workflows need a different provider.

Addressify uses the Australian government’s G-NAF dataset and says it updates every three months when new government data is released. Postal boxes can be autocompleted and parsed when the suburb appears in its dataset; boxes available only through Australia Post that require a per-call royalty are not validated.

Key features

Address processing

Validation and correction can catch incomplete or inaccurate Australian addresses, while parsing converts a loose string into structured fields. Geocoding supplies latitude and longitude, and reverse geocoding can work from coordinates to an address. The meshblock output adds a specific option for teams joining address records to ABS sociodemographic data.

Integration, security and data handling

Addressify supports HTTPS on every plan through its API endpoint. It can connect to software able to make HTTP GET calls and handle JSON, including customizable CRM and ERP systems and Microsoft Excel, Access and Word. That flexibility favors teams comfortable integrating an API; developers can also implement it for an additional fee.

The service says it is hosted in Microsoft Azure data centres in Sydney and Melbourne with geo-redundancy and automatic failover, which may take about five minutes to begin resolving to backup servers. Its privacy policy says submitted processing data remains the customer’s property, is not distributed to third parties, and can be deleted on request. HTTP GET address data is held in transient memory; transaction logs may be retained for up to 90 days with written customer approval for support.

Pricing

Addressify offers an entry-level free Trial, annual Lite and Pro plans, and custom pricing for Bulk / VAR / Dev. Prices are GST exclusive.

The Trial’s 1,000-call daily allowance makes it a bounded way to evaluate the API. Lite’s lower annual price suits internal organizational use when street-level validation is enough, but it does not verify whether units, levels or street numbers exist; Lite accounts can make only Lite API calls. Pro provides complete validation, which makes it the better fit when those details must be checked. Lite and Pro have no hard call limit, but usage is expected not to significantly exceed 20,000 calls per day, and excessive use that affects service—or inability to contact the customer—can lead to suspension. Software vendors embedding and reselling the service should consider VAR pricing rather than the internal-use plans.

Platforms

Addressify is listed for Android, iOS, Linux, macOS, Windows and web, alongside API access. Batch validation and address standardization are supported. Its local coverage means these capabilities are aimed at Australian addresses, not international address databases.

Who it's for

Addressify fits organizations that need Australian address data corrected or enriched across customer-facing forms and internal systems, especially when they also need structured fields, coordinates or meshblocks. The Lite-versus-Pro distinction matters most to teams validating unit, level and street-number existence. It is not the right choice for international coverage or for organizations relying on Australia Post-only postal boxes that need validation.

Pros and cons

• Pros: One API combines correction, parsing, autocomplete and geocoding, reducing the need to assemble separate address-processing functions.
• Pros: G-NAF-based Australian coverage and a stated three-month update cadence give Australian-focused teams a defined data source.
• Pros: HTTPS, transient handling of HTTP GET address data and customer-controlled deletion support privacy-conscious integrations.
• Cons: Lite checks street-level fields but not the existence of unit, level or street numbers, so organizations needing complete validation must pay for Pro.
• Cons: Coverage is local, and Australia Post-only postal boxes requiring a per-call royalty are not validated.
• Cons: The usage policy’s expectation of no significant excess over 20,000 calls per day and possible suspension makes it unsuitable to treat “no hard limit” as unrestricted volume.

Alternatives

For another Australian-focused option, Addresser offers a free eCommerce plan with 1,000 lookups per 30 days and autocomplete, while Addressify’s Trial allows 1,000 calls daily for 30 days. Readers comparing other address services can browse Address Verification Software.

Choose Ideal Postcodes Address Finder if a one-off credit purchase is preferable: its 200-credit plan costs £90.05, with credits valid for 12 months. Smarty Address Verification is worth considering when a 42-day free trial with 1,000 address lookups and no credit card requirement better suits evaluation.

Addrex Address Validation API may suit teams prioritizing a free beta allowance of 10,000 monthly lookups, spreadsheet upload, map coordinates and CSV export without automatic overage billing. Melissa Global Address Verification offers a free tier capped at 250 records per month and a 1,000-record monthly plan starting at $40 a month.

PostalUp offers a free 1,000-request allowance that never expires, with a limit of 10 requests per minute. Addressr is a free self-hosted open-source option with no hosted request limit, but the team supplies infrastructure, hosting, monitoring and data updates. AddressZen offers 1,400 verified addresses free for one year, with a 55,000-address bundle priced at $1,000 as a one-time purchase.

Verdict

Choose Addressify if your organization processes Australian addresses and wants correction, structured parsing and geocoding in one API, particularly when Pro’s complete validation is worth its $4,000 annual price. Look elsewhere if you need international coverage, validation of Australia Post-only boxes, or a lower-cost plan that verifies unit, level and street-number existence.
