What is the primary purpose of address validation in mail processing?

The primary purpose of address validation in mail processing is to confirm that an address is deliverable. This process involves checking the provided address against a database of valid addresses to verify its existence and correctness. Ensuring that an address can be delivered is crucial for effective mail processing and distribution, as it reduces the chances of returned or undeliverable mail, which can be a significant cost and efficiency concern for mailing operations. Validated addresses also help in maintaining an accurate mailing list, contributing to better customer communication and satisfaction.

While enhancing the appearance of mail, ensuring proper postage, and increasing sorting speed are all important aspects of mail processing, they are secondary to the fundamental goal of address validation, which is to ascertain that the mail can reach its intended recipient.
