A mail volume of 10 million or more results in what type of mailer ID?

A mail volume of 10 million or more results in a 6-digit mailer ID, which is essential for large volume mailers. The 6-digit mailer ID is part of the Intelligent Mail® system, which simplifies tracking and processing for high-volume mailings. This ID allows the United States Postal Service (USPS) to efficiently manage and route large quantities of mail, ensuring better service and delivery accuracy.

In contrast, lower mail volume categories correspond to fewer digits in the mailer ID, such as 5-digit IDs for smaller mailings. By using a 6-digit mailer ID, businesses that send a substantial amount of mail can take advantage of additional services, such as better pricing or enhanced tracking capabilities, which are crucial for businesses aiming to maximize their mailing efficiency and effectiveness.
