A common assumption is that countries maintain pristine address databases and all you need to do is connect to those and cross-reference your data. In reality, it is much more complicated.
Typically, a company will use an API to verify an address, which will check the input against the data of multiple international sources. However, the process is not always seamless and there are many things that can cause inaccuracies. These include language (half the world uses Latin, while the other half uses their own alphabet) and different formats (apartments, post office boxes, casing).
Then there are the country-specific issues. Usually, each country has its own unique address formatting, and it’s important to ensure that all data is properly formatted for each country to avoid any potential errors during onboarding or shipping.
Additionally, many countries have different rules for mandatory address fields like postal codes, and some even have requirements that are specific to their region, such as abbreviations or the order of words. This makes it difficult to build a robust international address validation system.
The solution is to have a service that is capable of validating addresses across all regions and languages. A good service will support all major global writing systems and alphabets, and have a database that is updated often to provide the best possible coverage. This way you can eliminate waste, improve customer experience and reduce lost packages and mail.
