I Keep Hearing I need a Mailer Id, Do I?

As of January 28, 2013, the USPS requires that all mail that receives automation discounts implements the Intelligent Mail Barcode (IMb). The mailer id is important to the USPS, because it enables them to identify who owns the mail. The confusion arises because depending on the mailing scenario in question, the answer of whether you need a mailer id changes. The easiest way to determine whether you need a mailer id of your own, or are okay using your vendor's mailer id is to identify the functional uses that are required with the IMb.

• For outbound Intelligent Mail requiring no additional services
  Most letter shops will allow you to use their mailer id, which is what we recommend.
• For outbound Intelligent Mail requiring Tracking and ACS
  The mailer id should belong to the organization charged with collecting and managing the Tracking and ACS data. This will most likely be your vendor.
• For outbound Full Service Intelligent Mail
  The mailer id should belong to the organization managing the uniqueness of the serial numbers. This will most likely be your vendor.
• For Intelligent Return Mail
  The mailer id should belong to the permit holder. Most likely this is your organization and not your vendor.

If you have determined that you do, in fact, need to have your own mailer id, it is easy to get. The USPS has provided an online application process that is quick and easy. You can access the application throught the Business Customer Gateway.
