International Address Validation Service
International Address Validation Service is the process of comparing an address outside the United States against a reliable database managed by authorities in that country. The results of this process can be used to standardize and correct addresses with the most accurate information possible, giving businesses the ability to reduce reworks, improve deliveries, save money on postal rates and customer service costs, and build a strong global base for business.
International address validation works using a variety of pattern matching techniques. These can range from deterministic matching (using precision to match each part of an address) to fuzzy or partial matching, which takes into account mistakes like extra blank spaces and minor spelling errors. A key component of international address validation is including the value designating the country of destination, which can be done by using either a full country name or an ISO Code Designation.
When choosing an international address validation service, it is important to consider the accuracy of the data and the country coverage rate. Different vendors may host their own databases or have partnerships with various global data sources, and the quality of these can vary significantly. Ultimately, the best address validation services will have high-quality data and a wide country coverage rate.
Additionally, it is useful to look for an international address validation solution that supports the use of different languages and writing systems. For example, some countries may have letters that are not represented in the Latin alphabet, so it is important to find a system that can translate these into other characters and writing systems.
