Intelligent Mail barcodes are fixed-length at 65 bars. Those 65 bars encode 20, 25, 29, or 31 digits of information, as zip codes are variable-length (0, 5, 9, or 11 digits).

Barcode Breakdown

A Intelligent Mail barcode has 5 sections.

  1. BI (Barcode Identifier) - 2-digit identifier assigned by the Postal Service.-digit 2 must be between 0 and 4 (inclusive).

  2. STID (Service Type Identifier) - 3-digit identifier assigned by the Postal Service for services requested for the mail.

  3. MID (Mailer ID) - 6- or 9-digit identifier assigned by the Postal Service that identifies the customer. 6-digit MIDs cannot begin with a 9, and 9-digit MIDs must start with a 9.

  4. Serial Number - 6- or 9-digit value to establish uniqueness. This value is 6 digits if a 9-digit MID is used, and vice-versa.

  5. Routing Code - 0, 5, 9, or 11-digit code for routing the mail to its final delivery point.
