Getting Started with Intelligent Mail
Full-Service Intelligent Mail offers mailers elimination of permit fees, address correction and visibility and tracking of mailings. USPS is proud to offer a list of certified software vendors and certified mail service providers that can help you start enjoying the benefits of Full-Service.
Solutions are available for small, medium and large volume mailers. Quick Service Guides are also available to provide an overview of mailing standards on the applicable subject matter
The Mailer Identifier (MID) is a field within the Intelligent Mail barcode that is used to identify mailers. MIDs are assigned by the USPS® to a Mail Owner, Mailing Agent or other service providers who request them.
MIDs are either a 9-digit or a 6-digit numeric code and are assigned based on annual mail volume criteria. One 9-digit MID is assigned to a business location without a volume requirement.
The USPS® Customer Registration ID (CRID) is a unique number that identifies a specific business location involved in a mailing. In order to submit electronic documentation (and receive Full-Service benefits), customers must have a customer registration ID assigned to their business location.
The Intelligent Mail barcode (IMb) is used to identify mailpiece movement through the postal system and support any additional services requested for that mailpiece. The STID defines the mailpiece as full-service or basic (non-automation) and is also used to determine the disposition of undeliverable-as-addressed (UAA) mail and the form of address correction that a mailer desires if any.
The Move Update standard is a means of reducing the number of mailpieces in a mailing that require forwarding or return by the periodic matching of a mailer’s address records with change-of-address orders received and maintained by the Postal Service™. Mailers who claim presorted or automation prices for First-Class Mail®, Standard Mail®, or Parcel Select Lightweight® prices must demonstrate that they have updated their mailing list within 95 days before the mailing date.
For those new to Full-Service Intelligent Mail, there are several guides, specifications and manuals that will get you started and give a broad overview of the fundamentals of the program.
Full-Service Intelligent Mail enables seamless acceptance and verification, as well as end-to-end visibility into the mail stream. It streamlines mail entry, provides visibility via scan data, expands access to scan data and mail-quality feedback to improve decision making, and improves efficiency. Full-Service is available for First-Class Mail, Periodicals, Standard Mail, and Bound Printed Matter cards, letters, and flats.

To participate in Full-Service Intelligent Mail®, mailers must submit information electronically. This computer-consumable version replaces existing hardcopies and includes the following: postage statement and qualification report.
The electronic Induction (eInduction) process simplifies the induction of drop shipments and expedited plant load mailings by leveraging existing eDoc, Intelligent Mail Container barcode (IMcb), and handheld scanner technologies to verify payment and preparation of commercial mail containers.
Seamless Acceptance automates the entry and verification of commercial mailings by leveraging electronic documentation, Intelligent Mail barcodes (IMbs), and information collected from handheld sampling devices and mail processing equipment scans.
The Mailer Scorecard provides a dashboard view of the results of the letter and flat mailing activity with the Postal Service over a calendar month. This view is available to both the mailer who submitted the electronic documentation for the mailing (eDoc submitter) and the mail owner/mail preparer.
Secure Destruction is a cost effective, secure, and convenient way to manage mail with personal protected information.
Part of the USPS® BlueEarth sustainability initiatives and an opt-in service, this new program securely shreds and recycles letter-size pieces of Undeliverable-As-Addressed (UAA) First-Class Mail® with personal protected information that would otherwise be returned to the sender (RTS).
The United States Postal Service® offers complimentary Reply Mail artwork via the Automated Business Reply Mail® (ABRM) tool, which allows Reply Mail customers to create approved USPS camera-ready artwork for domestic Reply Mail pieces in just a few steps.
Full-Service mailers have the opportunity to use the same permit at any location via the Mail Anywhere program. Entry into the Mail Anywhere program is limited to mailers who meet the quality thresholds for Full-Service electronic verification.
Informed Visibility Mail Tracking & Reporting (IV-MTR) is a near real-time, single source for all mail and mail aggregate tracking information.
Intelligent Mail® for Small Business Mailers (IMsb) is a free online tool which will allow you to produce the presorted Intelligent Mail barcodes (IMb) for your mail pieces, tray labels and submit an electronic postage statement to the acceptance units.
The Manifest Mailing System (MMS) is an automated system that allows a mailer to document postage and fees for all pieces in a mailing paid via permit imprint indicia.
Mail Quality Data (MQD-IV) leverages the Informed Visibility® Mail Tracking & Reporting (IV-MTR) application to enable mailers to receive uncapped Mail Quality Data. Detailed error data from the Mailer Scorecard is available for Full Service, Move Update, eInduction, and Seamless Acceptance.
Intelligent Mail Barcodes
The Intelligent Mail barcode (formerly known as the 4-State Customer Barcode) is the next generation of USPS® barcode technology used to sort and track letters and flats with unprecedented accuracy and ease.
The suite of Intelligent Mail barcodes contains three separate barcodes. The Intelligent Mail barcode is applied to individual mailpieces (letters, cards and flats). The Intelligent Mail Tray barcode is applied on tray labels that are attached to trays, sacks, and tubs, and the Intelligent Mail Container barcode is applied on container labels (or placards) that are attached to handling units such as pallets, containers, and APCs.
The suite of barcodes for Intelligent Mail share some common characteristics: identify the owner or sender of the mailpiece, identify the mailpiece or mail aggregate to allow for tracking, encode product or service requests on individual mailpieces or to include unique indicators for processing mail aggregates, and provide sorting and/or routing information.
The Intelligent Mail® barcode (IMb) is used to sort and track letters, cards and flats and offers greater versatility by allowing many services to be requested and embedded within one barcode. The Intelligent Mail barcode combines the data of the existing POSTNET™ and the PLANET Code® barcodes, as well as other data, into a single barcode.
The Intelligent Mail® Container barcode (IMcb) will be applied to Mailer-generated container labels and is designed to be scanned at acceptance and at other points throughout transportation and processing. The Intelligent Mail Container barcode allows each container to be associated with a unique mailing and facilitates tracking of containers throughout the mail processing network.
All tray label production systems are being transitioned to produce a 24-digit Intelligent Mail® (IM®) tray label in support of the USPS® "100% Visibility" strategy. The IM tray label allows for the unique identification of every tray, tub, and sack traveling throughout our mail processing and delivery network.
The Postal Service provides Intelligent Mail® barcode files, fonts and encoders, available for download.
CLDS is a web-based application that provides mailers with the capability to create, edit, and locally print or submit Intelligent Mail® tray label orders online for printing by the Topeka National Print Center (NPC).
NOTICE: Topeka National Printing Center (NPC) is working to fix a maintenance issue with their tray label printing press. All label orders are on hold and will not be accepted until further notice and while they make the necessary repairs. If users need tray labels immediately, they can use the local print option. Please see Section 9 of the CLDS Users Guide.
