Address validation is all about getting the details right before putting the package into the mail. It’s important, especially for businesses who want to deliver orders to customers and clients. International address verification helps businesses eliminate bad addresses which could lead to failed deliveries or even worse, lost orders.
An international address verification tool takes the information that the customer or prospect enters into your website forum and matches it with a reliable database managed by authorities in that country. It then standardizes the information to return a real-world address that is guaranteed to be correct. This helps businesses eliminate errors, builds trust, and ensures that the packages will reach the intended recipients.
When choosing an international address verification service, look for one that is CASS certified. This means that the API provider has been verified by USPS to be able to fill in missing information, standardize and update the address information regularly, and provide accurate results for all addresses. It should also have a variety of client libraries for various programming languages, including Python, JavaScript, C#, and iOS.
Some of the leading international address validation providers include Melissa Data, PostGrid, and A2Z Technologies. These companies have been around for years, offering top-notch address validation services and stellar support. They also have extensive clientele, including some of the biggest brands in the world. They are easy to use and feature straightforward documentation. They also offer a free trial to help you test their service before committing to a subscription.
