然而，Google for Merchant 服务的快速显示显示了几项将此项检查作为其服务一部分的内容。
我的建议是，假设有效性（只需在结帐时检查地址）并支付额外费用以确保自己免受欺诈性购买可能会更便宜。
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.
As Widor answered, many countries have fees/licenses associated with getting access to their postal data so. I am not aware of any free solutions that will verify postal data.
Also worth noting verifying addresses on Google Maps / Yahoo doesn't necessarily mean that they are a deliverable address for mail/packages.
There are some good commercial solutions that are affordable, consumption based, and do not require the purchase of software. If you decide to go that route, please take a look at StrikeIron (full disclosure, my company), we offer a Web Service with monthly/yearly subscriptions (with a free trial) to do international and North American address verification.

我认为即使在这个免费开源社区许可软件的时代，这个要求也很高。
至少在英国，您需要获得皇家邮政邮政编码地址文件 (PAF) 的许可才能进行此类详细检查。

正如维多尔回答的那样，许多国家/地区都有与访问其邮政数据相关的费用/许可证。我不知道有任何免费的解决方案可以验证邮政数据。
另外值得注意的是，验证 Google 地图/雅虎上的地址并不一定意味着它们是邮件/包裹的可投递地址。
有一些很好的商业解决方案，它们价格实惠，基于消费，并且不需要购买软件。如果您决定走这条路，请看看 StrikeIron（完全披露，我的公司），我们提供按月/按年订阅（免费试用）的网络服务来进行国际和北美地址验证。
最好的，
