Addressify vs Byteplant Address Validator

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.

Byteplant Address Validator checks postal addresses against reference data to assess deliverability and suggest corrections. It checks street, house number, postal code, and city combinations for validity and formatting, with coverage across more than 240 countries and territories. Its APIs provide autocomplete suggestions from freeform searches, geocoding, duplicate identification, and asynchronous bulk verification for up to 100,000 addresses in one request. Rooftop-accurate coordinates are available when geocoding is enabled. A free account includes 100 checks and corrections without payment details or an automatic subscription, and a free trial is listed. Credits purchased through pay-as-you-go do not expire; monthly subscriptions add credits automatically and unused credits roll over. Address checks use 1.0, 2.5, or 5.0 credits according to region, with additional credits for geocoding. Integrations include Zapier, plugins for WordPress, jQuery, and Node.js, plus CRM and e-commerce systems. Byteplant says data stays in the EU and personally identifiable end-user information is deleted within 14 days. It states a 99.9% availability guarantee and typical API responses within 125 milliseconds. The service cannot determine whether a person has moved; an existing former address may still validate.
