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.
PostalUp
PostalUp provides ZIP code databases and an address validation API for U.S. address data. The API supports standardization, verification, geocoding, and bulk processing; PostalUp says its address API uses USPS data refreshed monthly. Submitted addresses are processed in real time and are not permanently stored except as needed to provide the service or as permitted by the Privacy Policy. Developers can use API documentation, code examples, a playground, webhooks, and a Postman collection, with examples or options for JavaScript, Python, PHP, Ruby, cURL, Go, and Java. An OpenAPI specification is also available. Database downloads vary by product and include CSV, JSON, Parquet, GeoJSON, and Shapefile formats; listed data sources include USPS, Census, OMB, HUD, and TIGER. Use cases include e-commerce, real estate, logistics, marketing, insurance, and healthcare. The free API plan includes 1,000 requests and basic validation. Paid API plans start at $29 a month; separate database plans are annual, starting at $19 a year for ZIP Code Database Basic. Internal commercial use is included with downloads, but redistribution to customers requires a redistribution license.
