In their own words
Addresser
Addresser validates Australian and New Zealand addresses, email addresses, and phone numbers in real time or in batches. Its address API parses, standardizes, verifies, and enriches an address in one call, with results that can include a DPID, geocoordinates, SA1, SA2, LGA, and Meshblock data. Address Auto Complete offers suggestions through a JavaScript drop-in or REST API. Addresser states that it covers Australia, including PO Boxes, and New Zealand, with a 99.9% match rate against Australia Post and G-NAF. The API output meets AMAS criteria and may qualify for Australia Post bulk mail discounts. A WordPress plugin brings autocomplete to WooCommerce checkout, while HTTP-compliant requests allow API use from desktop, mobile, and web applications. Address data updates monthly in Australia and quarterly in New Zealand. Addresser says customer data is processed and stored in Sydney and not transferred outside Australia in ordinary operations; data is encrypted at rest and in transit. Free plans include 1,000 lookups over 30 days; Lite costs $10, paid once.
UPU POST*CODE API
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.
