Using IMb allows you to track letters and flats. When used in combination with IMb Tracing, a free service of the USPS, you will have the capability to track individual pieces of mail through the USPS Mail Tracking website. Although these are two different configurations and services, they are closely related.

To begin using barcodes, you will need a Mailer Identification (MID) number from the USPS. Once you have obtained a MID, then you will want to enable barcoding in Circulation:

• File > Configure List > Periodical Mail
• Check the box for “Barcoded Mailing” and “Meets deflection standards” (if your mailing qualifies. More about deflection standards here: http://about.usps.com/postal-bulletin/2010/pb22286/html/updt_002.htm)

•  Then, under Periodical Mail > Contact Information, type in your Mailer ID (MID) number and click ok.
