Addressify vs UPU POST*CODE API

Addressify is a cloud API for Australian address verification and processing in websites, forms, apps, and business systems. It can correct incomplete or inaccurate entries, including misspellings and incorrect postcodes, and parse free-form text into fields such as building name, unit, street, suburb, state, and postcode. Its autocomplete supports address entry; geocoding can return latitude and longitude from an address or identify an address from coordinates. It can also provide a meshblock for use with ABS sociodemographic data. Addressify uses the Australian government's G-NAF dataset and says it refreshes data every three months when new government data is released. The API supports HTTPS and can integrate with software that makes HTTP GET calls and handles JSON, including CRM and ERP systems and Microsoft Excel, Access, and Word. Lite validates street-level fields but not whether unit, level, or street numbers exist; Pro provides complete validation. The 30-day Trial costs nothing and permits 1,000 daily API calls. Lite costs $2,000 a year and Pro costs $4,000 a year; both prices are GST exclusive.

UPU POST*CODE API verifies international addresses using official locality names and postcode data from UPU member countries. Its checks cover a country’s postcode format, whether a postcode matches a locality, postcodes associated with a locality, and localities associated with a postcode. LocalityLike suggests official locality names and postal regions from the beginning of a partial locality input. The API is intended for designated postal operators, businesses, and individuals handling international addresses, including customs declarations, web shops, user platforms, and ERP systems. It can run as a CDS plugin, through the CDS API gateway or other middleware, or inside postal websites and local applications. Development guidance covers HTML, web applications, JavaScript form handling, and sample code for jQuery and Python. Documentation includes tutorials, quick-start guides, and developer tooling. UPU says response time is under one second and performance can be adjusted to expected call volume. Pricing is on request, with a free trial available by contacting UPU.
