Ideal Postcodes Address Finder

Ideal Postcodes Address Finder adds address autofill to online forms, with fuzzy matching to help correct common entry mistakes. Its suggestions are free; a credit is charged when someone selects an address and receives the full address. Address data covers more than 240 international countries, while UK data is refreshed daily against Royal Mail’s PAF and Ordnance Survey datasets. Each UK lookup includes a UPRN and rooftop geocodes at no extra cost. The service works on Android, iOS, web, as an extension, and through an API. That API is a REST service over HTTPS, returns JSON, and uses an API key. The maker lists more than 30 integrations, including Shopify, WooCommerce, Wix, BigCommerce, HubSpot, Zapier, Salesforce, and Microsoft Dynamics. Ideal Postcodes says its address capture supports screen-reader users and independent address completion. It states that it is ISO 27001:2022 and Cyber Essentials certified, keeps data in UK and EU data centres, and handles it in line with UK GDPR. Pricing is paid, with a 30-day trial and credit packages valid for 12 months.

Address Finder combines form autofill, address correction, and broad integration options, with specific support for accessible form completion. Buyers should account for credit-based charges and the API’s 100-address page limit.

It suits organizations adding address capture to forms, especially those seeking API access or integrations with listed commerce and business platforms. Its screen-reader support may also suit teams prioritizing independent form completion.

Ideal Postcodes Address Finder adds address autocomplete and correction to online forms, making it a strong fit for businesses that need UK address data and broad integrations. Its accessible-form support and included UK lookup data are useful advantages, but buyers should weigh one-off credit purchases against their expected usage.

Overview

Address Finder suggests addresses as users type and uses fuzzy matching to correct common entry mistakes. Suggestions do not consume credits; a credit is charged when a user selects an address and the full address is returned. That model keeps browsing suggestions free, while making completed lookups the cost to budget for.

UK address data is refreshed daily against Royal Mail’s PAF and Ordnance Survey datasets. Each UK lookup also includes a UPRN and rooftop geocodes at no extra cost, which adds location data without a separate lookup charge. The service also offers address data for more than 240 countries, giving it scope beyond UK-focused forms.

Key features

Form completion and accessibility

Autocomplete reduces manual address entry, while fuzzy matching is designed to catch common mistakes. The maker says the address capture supports screen-reader users and independent address completion, making this more than a convenience feature for forms that need to work for a wider range of users.

Integrations and API

Address Finder lists more than 30 integrations, including Shopify, WooCommerce, Wix, BigCommerce, HubSpot, Zapier, Salesforce and Microsoft Dynamics. That breadth suits teams looking to add address capture to an existing platform rather than build every connection themselves. For custom implementations, its API is a REST service over HTTPS that returns JSON and uses an API key for authentication.

Data handling and support

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. API requests use TLS 1.3 encryption in transit, with a hybrid post-quantum key exchange when the client supports it. Support is available by email, phone and live chat from 9.00 AM to 5.00 PM Monday to Friday UK time, excluding public holidays.

A practical API constraint is its limit of 100 addresses per page for a postcode. A postcode with more results may require additional pages, so implementations that need to retrieve large result sets should account for pagination.

Pricing

Address Finder is paid, with a 30-day trial and no free plan. The pricing note says “From £9,” while the listed credit bundles are one-off purchases with credits valid for 12 months:

The 200-credit bundle is the smallest listed commitment and may suit a lower-volume rollout; larger bundles provide more credits for teams expecting greater use. All bundles expire after 12 months, so buyers should match the purchase to likely completed lookups rather than suggestions. The 30-day trial offers a way to assess the service before buying, but there is no ongoing free tier.

Platforms

Address Finder is available on Android, iOS, web, as an extension, and through its API. The combination covers app and browser contexts as well as custom integrations.

Who it's for

It is best suited to businesses adding address capture to online forms, especially those relying on UK addresses, needing international coverage, or working within one of its listed commerce, CRM or automation integrations. It is also a considered option when accessible address completion and included UK geocodes matter. Teams seeking a permanent free tier or usage billed without expiring credit bundles should look elsewhere.

Pros and cons

• Pros: More than 30 integrations plus API access give businesses multiple implementation paths.
• Cons: There is no free plan, and completed address returns consume credits, requiring paid usage.

Verdict

Choose Ideal Postcodes Address Finder if your forms need reliable UK address capture, accessible completion and integrations that fit your existing stack. Its daily-refreshed UK data, included geocodes and international coverage make a strong case, but the credit model and 12-month expiry are meaningful trade-offs. Look elsewhere if a permanent free plan or non-expiring usage is essential.
