METANORM AI Address Validation checks and suggests corrections for both billing and shipping addresses in WooCommerce Classic Checkout, Block Checkout, and My Account address forms.

When customers place an order or save an address in My Account, Metanorm checks the address and may suggest a correction.

Customers can review suggested corrections directly in the checkout or account address form and choose whether to use the suggestion or keep their entered address.

External Services

Address validation requires a paid Metanorm subscription and an API key. The plugin itself is free.

Service provider legal notice: Legal notice

When a customer places an order or saves an address in My Account, the plugin sends the address details needed for validation to Metanorm. Depending on the service configuration, Metanorm may use AI and geocoding providers to process them.

The transmitted data may include:

Address line 1 (street and house number).
Address line 2 (additional address information).
Postal code, city and country code.
Browser language and a random request ID.

The API key is used to authenticate requests. Separate name, company, email, telephone and state fields are not sent for validation. Customers may enter personal information in address lines.

Without a saved API key, the plugin does not send addresses to Metanorm. “Test connection” checks whether the service is reachable without sending an address or API key.

See the service terms and privacy policy for data retention and other providers involved in processing. Shop owners should describe address validation in their own privacy notice.

For troubleshooting, the plugin records request IDs, response status, duration and error codes, but no addresses or API keys. To prevent misuse, it temporarily counts requests from each connection.

Source Code

The plugin includes its source code in src/. See BUILDING.txt for build instructions.
