Intelligent Mail barcode

A Barcode Identifier is assigned by the United States Postal Service to encode the presort identification that is currently printed in human readable form on the optional endorsement line (OEL). It is also available for future United States Postal Service use. This is accomplished using two digits, with the second digit in the range of 0–4. The allowable encoding ranges are 00–04, 10–14, 20–24, 30–34, 40–44, 50–54, 60–64, 70–74, 80–84, and 90–94.

The first digit of the Barcode Identifier is defined as:

A three-digit value represents both the class of the mail (such as first-class, standard mail, or periodical), and any services requested by the sender.

Basic STIDs, for the purpose of automation only, are as follows:

For a detailed list of STIDs, see Appendix A of the USPS Guide to Intelligent Mail Letters and Flats[4] or Service Type Identifiers.[5]

A six- or nine-digit number assigned by the United States Postal Service identifies the specific business sending the mailing. Higher volume mailers are eligible to receive six-digit Mailer IDs, which have a larger range of associated sequence numbers; lower volume mailers receive nine-digit Mailer IDs. To make it possible to distinguish six-digit IDs from nine-digit IDs, all six-digit IDs begin with a digit between 0 and 8, inclusive, while all nine-digit IDs begin with the digit 9.

A mailer-assigned six- or nine-digit ID specific to one piece of mail, to identify the specific recipient or household. The mailer must ensure that this number remains unique for a 45-day period after the mail is sent if a Full Service discount is claimed; otherwise, it does not have to be unique. The Sequence Number is either six or nine digits, based on the length of the Mailer ID. If the Mailer ID is six digits long, then the Sequence Number is nine digits long, and vice versa, so that there will always be fifteen digits in total when the Mailer ID and the Sequence Number are combined.

This section of the code may be omitted, but if it is present, the five-, nine-, or eleven-digit forms of the ZIP code are also encoded in the Intelligent Mail barcode. The full eleven-digit form includes the standard five-digit ZIP code, the ZIP + 4 code, and a two-digit code indicating the exact delivery point. This is the same information that was encoded in the POSTNET barcode, which the Intelligent Mail barcode replaces.

Over the years, more and more companies have been applying barcodes as part of document creation, with all barcode information included in the initial data payload. This trend has been driven by other initiatives, such as transpromotional transaction documents, where the goal is to produce individualized, relevant statements. Creating barcodes at this point in the process may require some added effort, but with the proximity to databases and business applications, some mailers may find it easier to track data back to its original data source (for example, to correct an address).

With today's document output technologies, mailers can modify and reengineer print streams, moving and adding information (such as barcodes) on the fly. Likewise, mailers can print barcodes directly on envelopes using an envelope finishing system. Either way, this approach enables mailers to centralize and standardize barcode creation on the production floor using the original data files without impacting upstream business applications.

Many organizations may not be able to place Intelligent Mail Barcodes during the document composition step. There may not be sufficient resources to make the production modifications, or the transaction print data stream may arrive already composed, without the capability to reach back and change the composition process. But the organization may still want to place the code into the electronic document before it is printed, rather than later in a post-print production process.

Adding Intelligent Mail barcodes post-composition into the electronic print file allows organizations to simultaneously clean up all their transaction print streams while adding the codes they need. Other document re-engineering options can also be made at this step, such as adding 2D barcodes for use by the newer Automated Document Factory systems, checking address blocks, and adding more marketing messages.

Many organizations find that by commingling multiple smaller print streams before printing into one larger stream (or a few larger streams, sorted by criteria such as weight or number of inserts) they can gain efficiencies and reduce overall postage costs. During this electronic commingling process IMBs can be added to the documents and mail pieces in the new stream(s). This is an option to in-house sortation.

When mailers run separate jobs and then want to combine them to achieve additional postal savings, they can physically sort mail after it is produced using sorter equipment. With new or upgraded sorter technology, mailers can accommodate the new Intelligent Mail barcode at the end of the mail production process. This is an option to electronic commingling.

Third-party presort houses provide mailers an easy way to comply with Intelligent Mail mandates and also provide them with the benefits of commingled mail. Even if a third-party applies the barcode, however, it may still be possible for the United States Postal Service to monitor the quality of the sortation using a mailer's unique Mailer ID. It is important for mailers to coordinate sequence numbers with their vendor so they can leverage OneCode ACS and OneCode Confirm services.
