International deliverability insights

Lob's International Deliverability provides greater visibility into an address’s delivery response so customers can make more informed decisions about how they manage international address data. Customers are able to understand when a portion of the address has been corrected and if it has resolved the deliverability issues. To leverage this data, review the complete API documentation under Status.

International autocomplete

International address autocompletion for non-US addresses is not currently available. If you believe this feature is integral to your business, please reach out to support to see if we can support your needs.

Configurable transliteration

Configurable Transliteration provides Address Verification customers greater flexibility and customization when operating around the world. Lob ensures that addresses are correct and deliverable while providing optionality for the address response to be in the native language. This means a customer is able to provide cart checkout messaging that adapts based on where the end customer is located thus creating a more personalized experience. It also means that when working with foreign languages with non-Latin characters the data is seamlessly transliterated and mapped for normalized data storage.

To customize your language response, review the complete API documentation under x-lang-output.
