Managing your USPS Mailer ID on the SendPro MailCenter 1000, 2000, and 3000

You will need to add a USPS Mailer ID when you send mail using Electronic Return Receipt (ERR). The mailer ID is a 6 or 9-digit number that you receive when you submit Form 5053, Bulk Proof of Delivery to the USPS.

Adding the Mailer ID number

1. Select Settings from the Home screen.
2. Select Applications.
3. Select Tracking Services.
4. Enter the Mailer ID number in the Mailer ID field.

If the Mailer ID has been added or changed and you already had pre-existing jobs created using ERR, you need to manually edit the Mailer ID in those jobs. The global Mailer ID set in the above steps will not override pre-existing jobs.

Editing the Mailer ID on a pre-existing job

1. Select Jobs from the Home screen.
2. Select the job containing ERR that you want to edit. Select OK.
3. Edit the Mailer ID field on the left side of the screen.
4. Select Save.
