International address verification

No matter the distance, make your messages heard. We validate addresses—domestic and abroad. That’s address verification for over 240 countries and territories across the globe. This means shipments reach their destinations, returned mail is no longer a problem, and you’re able to better communicate with customers.

Test out our international address verification for yourself

International customers are a vital part of the operations of many businesses and organizations, which makes it essential that you are able to communicate with them quickly and effectively. International customers do not get packages or letters from you, and your mailing costs go up because of redundant mailings and additional efforts to deliver your mail.

International address validation is the best way to ensure the accuracy of your international addresses and reduce mailing problems based on incorrect customer data. The right international address lookup tools will help you to have the right address for each customer the first time and cut down on delivery mistakes.

Our international address validation API software tools are used by satisfied clients across the country to improve their international data for the sake of improved communication with their customers.
