Addresser vs Ideal Postcodes Address Finder

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.

Ideal Postcodes Address Finder adds address autofill to online forms and uses fuzzy matching to correct common address-entry mistakes. Suggestions are free; a credit is charged when a user selects an address and receives the full address. Address data covers more than 240 international countries. UK data is refreshed daily against Royal Mail’s PAF and Ordnance Survey datasets, and each UK lookup includes a UPRN and rooftop geocodes at no extra cost. The maker says its capture flow supports screen-reader users and independent address completion. It lists more than 30 integrations, including Shopify, WooCommerce, Wix, BigCommerce, HubSpot, Zapier, Salesforce, and Microsoft Dynamics. The REST API runs over HTTPS, returns JSON, and uses an API key; requests use TLS 1.3 encryption in transit, with hybrid post-quantum key exchange when supported by the client. Ideal Postcodes states that it is ISO 27001:2022 and Cyber Essentials certified, stores data in UK and EU data centres, and handles it in line with UK GDPR. Plans are one-off credit purchases, with credits valid for 12 months. The listed 200-credit plan costs £90.05 as a one-time purchase; the pricing note says From £9 and includes a 30-day trial.
