Barcode on mail

You're referring to the barcode on a mailpiece!

In the United States, the United States Postal Service (USPS) uses a barcode called the Intelligent Mail barcode (IMb) to track and sort mail. The IMb is a 65-character barcode that contains information about the mailpiece, such as:

  1. Delivery Point Sequence (DPS) number: a unique identifier for the mailpiece
  2. Mailer ID: the ID of the mailer (sender)
  3. Service type: the type of mail service used (e.g., First-Class, Priority Mail)
  4. Postage payment: the amount of postage paid
  5. Destination ZIP Code: the ZIP Code of the mailpiece's destination

The IMb is printed on the mailpiece in a specific location, usually in the top-right corner of the envelope or package. The barcode is read by automated processing machines at USPS facilities, allowing for efficient sorting and tracking of mail.

Here are some benefits of the IMb:

  1. Improved tracking: The IMb enables USPS to track mailpieces more accurately, reducing errors and improving delivery times.
  2. Increased efficiency: The IMb allows for faster sorting and processing of mail, reducing the need for manual sorting and increasing the speed of delivery.
  3. Cost savings: The IMb helps USPS reduce costs by minimizing the need for manual processing and reducing the risk of lost or misdirected mailpieces.
  4. Enhanced customer service: The IMb provides customers with more detailed information about their mailpieces, such as delivery status and tracking information.

If you're a mailer, you can use the USPS's online tools to generate and print the IMb on your mailpieces.
