Today’s DMM Advisory

The DMM Advisory is an email news brief that comes out periodically from the USPS. Today’s bulletin contained the following info:

Expanding the Use of Intelligent Mail Barcodes

Effective March 1, 2007, the Postal ServiceTM will allow mailers to use Intelligent Mail® barcodes (previously called “4-State Customer Barcodes”) on automation-rate First- Class Mail®, Periodicals, and Standard Mail® letters for rate eligibility, in lieu of POSTNETTM delivery point barcodes (DPBCs). We will revise 202, 233, 243, 707, and 708 of Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) to incorporate this change in our March update.

Currently, mailers who are Confirm® service subscribers or Address Change Service participants use either of two types of barcodes – an Intelligent Mail barcode or a DPBC – on automation-rate letters for rate eligibility. Allowing mailers to use the Intelligent Mail barcode on all automation-rate letters encourages use of this new barcode.

When mailers choose to use the Intelligent Mail barcode, they must include a numeric Business Entity Identifier. Mailers who do not have an assigned Business Entity Identifier may obtain one by contacting the PostalOne!® Help Desk at 800-522-9085. Complete specifications for Intelligent Mail barcodes are defined in USPS-B-3200, which is available for download at

As our technology evolves, we will continue to expand the use of Intelligent Mail barcodes.


All the Window Book Mailing products are able to utilize 4-State barcode information.

Best wishes,
