AddressValidation

AddressValidation for Magento 2

Introduction

The goal is to make an extension that can both lookup and validate customer addresses. This extension should solve the problem that orders are shipped to non-existing addresses. The extension will be a bridge between various address lookup services and magento.

Approach

• We make the assumption that an address must be valid, once we get an address from the lookup.
• We do not use a special "house number" address attribute but make usage of the different address lines (configurable).

Address lookup service interface parameters

Fields needed for looking up address (multiselect)

• Country (always needed)
• State (optional)
• Address (optional
• House number (optional)
• Postcode (optional)

List of countries that are allowed/supported by the service (multiselect)

Is the user allowed to order without a valid address (dropdown)

• No (not allowed to order)
• Yes (enter address manually)

Address Validation (and formatting)

Optional reg-ex validation can be added for the following fields

• Address
• House number
• Postcode Optional there could be autocorrection (like removing or adding spaces from dutch postcodes etc)

Backend configuration

In the admin, per country you can enable "lookup/validation" by setting the following parameters.

• An "address lookup service" (services are configured individually)
• Configuration for which of the address fields is the house number and which is the streetname
• An address validator

Workflow frontend

• Customer enters address (in checkout)
• When necessary fields are entered (Depending on the adapter) the form will silently submit itself to a controller
• The controller will return one of: -- A single address > we use this as a valid address -- A list of possible addresses > user must select one of the addresses or choose to set an address manually -- No address > enter address manually or do not order (depending on setting)

Workflow backend

• An address that is submitted for lookup will be validated before looking up according to the validator
• It the address is valid a lookup will be done
• An address (both from a service, or entered manually) that is submitted as "quote address" will be validated according to the validator
