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.
