For address providers
Your address data. Every store system. One integration.
Address Validation iO sends every address to the provider that's best for that country. Integrate once and reach merchants on Shopify, Shopware and WooCommerce — in the countries where your data is strongest.
Why partner with Address Validation iO
Built for providers who are best somewhere.
One integration, three platforms
Shopify, Shopware 6 and WooCommerce, plus headless storefronts and the API. No separate apps or plugins to build and maintain.
Win country by country
Per-country routing means national and regional specialists don't need global coverage. You become the main provider where your data is best.
Proven on real orders
Merchants A/B-test providers on their own orders, so strong data shows in the results.
Backup traffic
Where you aren't the main provider, you can still serve as the backup when the main one fails or is unsure.
No merchant overhead
Address Validation iO handles onboarding, merchant UI, billing and first-level support.
Visibility
You are listed on the Providers page and on the coverage map with your documented coverage.
Insights
Aggregated performance per country, such as match rates, with no personal data.
EU-hosted, privacy-first
Addresses are only sent to the provider that checks them. Hosting in Frankfurt, with a DPA in place.
