A good international address validation api saves businesses time and money by removing the need to maintain complete address files locally. It also optimises processes, reduces undelivered mail, addresses errors at the point of entry, and saves on the costs associated with reprinting or returning packages.
The best international address validation tools crosscheck an international address against a database managed by the authority in charge of that country’s postal system to make sure it is formatted correctly for mailing. They also correct for spelling mistakes, replace common roadway identifiers (street and parkway) with their standard abbreviations, and identify the state code and city name where necessary.
Many of the same issues that plague domestic address verification are exacerbated when dealing with international addresses. These include formatting differences, language difficulties, and regional variations in terminology. Fortunately, most of these problems can be handled by an international address validation service that offers freeform or structured address lookup, validating and standardizing for over 250 countries.
A good international address validation api will offer an automatic self-completion function that allows webshop customers or data entry employees to enter just part of an address and then select or confirm the remaining suggested fields. This not only makes the process faster and easier for end users, it is also more accurate than manually typing in full addresses. This is because it uses smart technology to recognise and correct common spelling errors and other address inaccuracies. It can even recognise characters from different writing systems and transliterate them into Latin characters for use in the reference data.
