Addressify

Addressify is a cloud API for verifying, correcting and enriching Australian addresses in websites, forms, apps and business systems. It suits organizations that need Australian address workflows connected to an API. Its broad processing toolkit is useful, but the gap between Lite and Pro validation makes plan choice consequential.

Overview

Addressify combines address validation and correction with parsing, autocomplete and geocoding. It can split a free-form entry into fields such as building name, unit, street, suburb, state and postcode, and correct mistakes including misspellings and incorrect postcodes. Geocoding adds latitude and longitude; reverse geocoding can work from coordinates, and the service can provide a meshblock for use with ABS sociodemographic data.

Coverage is Australian only. Addressify uses the government’s G-NAF dataset and says it updates data every three months when new government data is released. That defined source and cadence suit Australian-focused projects, but teams handling international addresses will need another service.

Postal boxes can be autocompleted and parsed when the suburb is in Addressify’s dataset. Boxes available only through Australia Post and requiring a per-call royalty are not validated, a relevant limitation for businesses whose customers rely on those addresses.

Key features

Validation, parsing and geocoding

Addressify can check address entries, standardize them, split them into structured fields, and autocomplete them in forms. Its API can also add coordinates and meshblock data. This breadth makes it useful beyond checkout validation, including for business systems that need cleaner address records or location data.

The main qualification is validation depth. Lite checks street-level fields but does not verify whether a unit, level or street number exists; Pro provides complete validation. Lite accounts are restricted to Lite API calls, so teams that require those checks cannot treat the lower paid tier as a full substitute for Pro.

Integration, hosting and data handling

The API uses HTTPS on every plan at https://api.addressify.com.au. Systems that can make HTTP GET calls and handle JSON can integrate with it, including customizable CRM and ERP systems and Microsoft Excel, Access and Word. The service says it runs in Microsoft Azure data centres in Sydney and Melbourne with geo-redundancy and automatic failover; resolving to backup servers may take about five minutes to begin.

Submitted processing data remains the customer’s property under Addressify’s privacy policy, and customers can request deletion from the secure server. HTTP GET address data is held only in transient memory. Transaction logs may be stored for up to 90 days when the customer gives written approval for support. These terms offer a defined data-handling boundary, though the optional support logging period may matter to organizations with stricter retention requirements.

Pricing

The 30-day Trial costs 0.00 USD and allows 1,000 API calls per day. It includes street-level validation, unit, level and street-number checks, and geocoding. That makes it a useful short evaluation tier, but its daily allowance and fixed 30-day term limit its use as a continuing free service.

Lite costs $2,000 a year, billed annually, with prices GST exclusive. It has no hard call limit and includes street-level validation, unit, level and street-number fields, and geocoding; its usage expectation is that calls will not significantly exceed 20,000 per day. The field list should not be confused with existence checks: Lite does not validate whether unit, level or street numbers exist. It fits organizations needing street-level checks and a paid API, but not those relying on complete address validation.

Pro costs $4,000 a year, billed annually, with prices GST exclusive. It includes the same stated capabilities and usage expectation, while providing complete validation. It is the appropriate tier for organizations that need existence checks for unit, level and street numbers. Both paid plans have no hard call limit, but the acceptable usage policy expects usage not to significantly exceed 20,000 calls per day and permits suspension if excessive use harms service or the customer cannot be contacted.

Bulk / VAR / Dev has custom pricing. It covers bulk calls for large organizations, reseller accounts for software vendors embedding Addressify for third parties, and free developer-only accounts. Lite and Pro are for internal organizational use; software vendors reselling the service should consider the VAR account instead. Addressify developers can implement the API for an additional fee.

Platforms

Addressify supports Android, iOS, Linux, macOS, Windows and web workflows, alongside API access. In practice, compatibility depends on a system being able to make HTTP GET calls and process JSON, so the platform range does not remove that integration requirement.

Who it's for

Addressify fits organizations that process Australian addresses and want validation, parsing, autocomplete or location enrichment in their existing software. Lite is for teams whose needs stop at street-level validation; Pro is for those that need complete checks. Software vendors embedding the service for resale should look at VAR pricing. International address operations and workflows centered on Australia Post-only postal boxes are poor matches.

Pros and cons

• Pros: Validation, correction, parsing, autocomplete and geocoding are available through one Australian-focused API, with meshblock data as an additional option for ABS integration.
• Pros: HTTPS is supported on all plans, and the privacy policy keeps submitted processing data the customer’s property.
• Cons: Lite does not check whether unit, level or street numbers exist, despite including those fields; complete validation requires Pro at twice Lite’s annual price.
• Cons: The stated 20,000-calls-per-day expectation and possible suspension make the lack of a hard limit less reassuring for consistently high-volume workloads.
• Cons: Coverage is limited to Australia, and some postal boxes requiring Australia Post’s per-call royalty are not validated.

Alternatives

For another Australian address service, Addresser has a free eCommerce plan with 1,000 lookups over 30 days and autocomplete, as well as a free plan and trial. Melissa Global Address Verification is the alternative to consider when the workflow needs broader geographic reach: its platforms include self-hosted deployments, and its free plan covers 250 records per month.

PostalUp suits a small request volume or a quick standardization trial: its free tier never expires, covers 1,000 requests and includes basic validation, with a 10-requests-per-minute cap. Addrex Address Validation API offers a larger free beta allowance of 10,000 monthly lookups, spreadsheet upload, map coordinates, a usage dashboard and CSV export.

AddressZen is an option for buyers who prefer a one-time address bundle: its $1,000 USD bundle covers 55,000 verified addresses and includes US and other coverage. Lob Address Verification may suit a mailing workflow, with a Developer plan for up to 6,000 mailings, one user and additional per-address charges for US and international verification.

Addressr offers a self-hosted open-source option with no hosted request limit, provided the team supplies infrastructure, monitoring and data updates. PostNL Address Validation API is an alternative for Benelux addresses when the customer has a PostNL parcel contract. Browse the Address Verification Software category for more options.

Verdict

Addressify is a strong fit for organizations building Australian address processing into their own systems, especially when parsing, geocoding and meshblock enrichment matter alongside validation. Choose Pro when unit, level and street-number existence must be checked; Lite’s lower price does not provide that assurance. Look elsewhere for international coverage, Australia Post-only postal boxes, or daily usage that may regularly exceed the policy’s expected level.
