Postal addresses are at the heart of multiple services

Although digital channels are becoming more and more important in customer relations, the postal service is still a valued channel for many scenarios and industries. For example, in e-commerce orders are sent by mail or home delivery service. It is impossible to get items to the right mailboxes without verified postal addresses. The verification of postal information involves both the real-time entry of addresses by your customer service department or the customers themselves, and the addresses stored in your database, which may change over time. This is why managing the quality of customer addresses and ensuring they are valid and up-to-date is an integral part of your customer data quality efforts.

Beware of unvalidated address information

Between a business address, home address, primary or secondary address, your customers may have multiple addresses. They’ve also possibly moved, changed companies, or actively reside in different locations. Without verification, your mail and deliveries are subject to being undelivered or returned, potentially incurring losses to your business. In addition to your logistical hassle, these mailing hiccups affect customer relationships. Nothing is more frustrating than not receiving their packages. Data quality is crucial to ensuring you the correct values for street name, city, zip code, and more in real time, and that you have reliable information in your contact database or can modify an address in case of change.

The quality of verified addresses better guarantees of delivery to the right address

Data quality allows you to capture the exact address in real time with the help of data entry assistance to correct basic info, like adjusting a postal code, according to postal standards and to update them when a customer's contact information needs to be changed. The best data quality solutions are based on international standards approved by the postal services of the respective countries, ensuring smooth international deliveries.
