What is a mailer id?

A mailer ID is a unique identifier assigned to a mailer by the United States Postal Service (USPS). It is used to track and monitor mailings, allowing the USPS to identify and measure mail quality.

Here are some key points about mailer IDs:

1. Purpose: The primary purpose of a mailer ID is to monitor and assess mail quality and provide data for postal discounts and incentives. It helps the USPS measure the effectiveness of mailings and ensure proper processing.

2. Unique Identifier: Each mailer ID is unique and typically consists of a 9-digit code. It is given to businesses, organizations, or individuals who regularly send bulk mail. Mailers can have multiple IDs if they have different types of mailings or multiple locations.

3. Application Process: To obtain a mailer ID, mailers need to apply through the USPS Business Customer Gateway or PostalOne! website. A mailer must meet specific criteria set by the USPS to be eligible for a mailer ID.

4. Mailer Scorecard: The USPS uses the data gathered from mailer IDs to generate a Mailer Scorecard. This scorecard provides mailers with detailed information on the quality of their mailings, including errors and performance metrics.

5. Postal Discounts: Mailers who maintain high-quality standards, verified through the mailer ID, can qualify for postal discounts and incentives. The USPS offers various programs like the Seamless Acceptance program that benefits mailers with consistent and accurate mailings.

6. Mail Tracking: Mailer IDs can be used to track individual mailpieces as they move through the USPS system. This tracking data can be accessed by the mailer to monitor the delivery status and provide customer updates.

7. Compliance: Mailers are expected to meet certain criteria and guidelines set forth by the USPS under the mailer ID program. This ensures that mailings are prepared, presented, and addressed correctly to facilitate smooth processing and delivery.

In summary, a mailer ID is a unique identifier provided by the USPS to monitor and assess the quality of bulk mailings. It helps mailers track their mailings, qualify for postal discounts, and maintain compliance with USPS standards.
