Ideal Postcodes Address Finder

What Ideal Postcodes Address Finder is
Ideal Postcodes Address Finder adds address autocomplete to online forms and uses fuzzy matching to correct common address-entry mistakes. A user can select a suggested address to receive the full address; suggestions are free, and a credit is charged for that completed selection. Address data is available for more than 240 international countries. For UK lookups, every address includes a UPRN and rooftop geocodes at no extra charge, while the UK data is refreshed daily against Royal Mail's PAF and Ordnance Survey datasets. The maker says the capture flow supports screen-reader users and lets them complete addresses independently. Address Finder is available through web, iOS, Android, extensions and API. Its REST API runs over HTTPS, returns JSON and authenticates with an API key. The maker lists more than 30 integrations, including Shopify, WooCommerce, Wix, BigCommerce, HubSpot, Zapier, Salesforce and Microsoft Dynamics. Ideal Postcodes states that it is ISO 27001:2022 and Cyber Essentials certified, holds data in UK and EU data centres, and handles it in line with UK GDPR. Credit purchases are one-off and valid for 12 months; the listed 200-credit purchase costs £90.05, paid once.
Who it suits
Address Finder suits businesses that need address autocomplete in online forms, including those serving users in multiple countries. It is also relevant to teams using its listed ecommerce, CRM and automation integrations, or building against a REST API.
