I am looking for an address validation service which is not only free of charge but also available world-wide (or at least in Europe).

Background: I want to check the customers address in the background of a checkout process in an online shop. Currently this check is done manually by service staff after the the order is placed.

Note: I don’t want to bother the user with error messages, the check should only be done in the background to reduce effort and time in the backend.

Every free service I found (Google Maps, Yahoo Places) exludes the right to use their data within any scenario like that. And any commercial I found till now is a bit to expensive in that context.

Thanks for any hint 🙂

    I think that’s asking a lot, even in this age of free open-source community-licensed software.

    In the UK at least, you need to licence the Royal Mail’s Postcode Address File (PAF) for that sort of detailed check.

    However, a quick Google for Merchant services shows up several that include this check as part of their service.

    It may be cheaper to assume validity (just sense-check the address during checkout) and pay a premium to insure yourself against fraudulent purchases would be my advice.
