Mailing barcode

A mailing barcode, also known as a postal barcode or Intelligent Mail barcode (IMb), is a unique barcode used by the United States Postal Service (USPS) to track and sort mail. It is a 65-character barcode that contains information about the mailpiece, such as the sender's and recipient's addresses, the weight and size of the mailpiece, and the postage amount.

The mailing barcode is used to:

  1. Sort and route mail: The barcode helps the USPS sort and route mailpieces to the correct destination.
  2. Track mail: The barcode allows the USPS to track the movement of mailpieces and provide delivery confirmation.
  3. Verify postage: The barcode verifies that the correct postage has been applied to the mailpiece.
  4. Provide delivery information: The barcode provides information about the delivery status of the mailpiece, such as whether it has been delivered or returned to the sender.

The mailing barcode is typically printed on the mailpiece using a special printer or label. It is usually located in the top right corner of the mailpiece, although it can be placed elsewhere depending on the specific requirements of the mailer.

There are different types of mailing barcodes, including:

  1. Intelligent Mail barcode (IMb): This is the most common type of mailing barcode used by the USPS. It contains 65 characters and is used for First-Class Mail, Priority Mail, and Parcel Post.
  2. PLANET Code: This is a 12-digit barcode used for international mailpieces.
  3. USPS OneCode: This is a 12-digit barcode used for mailpieces that require additional tracking information.

To create a mailing barcode, you will need to use a software program or online tool that is certified by the USPS. The program will ask for information about the mailpiece, such as the sender's and recipient's addresses, the weight and size of the mailpiece, and the postage amount. The program will then generate the mailing barcode and print it on the mailpiece.
