Addressify vs Ideal Postcodes Address Finder

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.

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.
