What Are Intelligent Mail Barcodes?

Intelligent Mail Barcodes (IMbs) are advanced, USPS-developed barcodes that uniquely identify and track individual mailpieces throughout the postal system. Used on letters, flats, and postcards, IMbs combine routing and tracking data into a single barcode, enabling full visibility from print to delivery.

Each IMb encodes critical information, including:

• Mailer ID – Identifies the sender

• Service Type Identifier (STID) – Specifies the mail class and any optional services like tracking or address correction

• Sequence Number – A unique identifier for each piece of mail

• Routing Code – ZIP Code or delivery point information to guide USPS sorting and delivery

The IMb is formatted as a 65-bar, four-state barcode, meaning it uses four types of bars to encode multiple data points in a compact space.

How Intelligent Mail Barcodes Work In Practice

We apply IMbs to bring full visibility and precision to every mailpiece. Here’s how the process unfolds on our production floor:

1. Barcodes Are Generated: Each piece is assigned a unique barcode, containing mail class, routing info, and tracking IDs, built from your recipient data.

2. Printed On Demand: The IMb is printed directly onto each document or envelope during production as part of the variable data printing process, ensuring each mailpiece is completely individualized.

3. Mail Is Sorted & Entered: Mail is automatically sorted and introduced into the USPS network.

4. Tracking Begins Immediately: IMbs are scanned throughout the mailpiece’s journey, including when the mailpiece is en route, when it’s arrived at the local post office, and when it’s delivered, creating a complete chain of custody.

5. Delivery Data Comes Back to You: Every time an IMb is scanned, the data is sent directly back to our real-time tracking platform and compiled into easy-to-use reports, dashboards, or API feeds, giving you full transparency at every stage.

Who Benefits from Intelligent Mail Barcodes?

Industries where IMbs can enhance your workflow include:

• Finance: Ensure compliance with SEC and FINRA regulations, track time-sensitive communications like statements and disclosures, and reduce fraud through piece-level verification.

• Healthcare: Support HIPAA compliance by tracking sensitive patient mail, reduce missed appointments, and improve patient communications with real-time delivery visibility.

• Government: Create audit trails for election ballots, tax notices, and official correspondence, while improving transparency and reducing returned mail costs.

• Marketing: Track delivery of campaign mail in real time, sync physical mail with digital outreach, and use delivery predictions to optimize timing of marketing initiatives and boost engagement.

• Legal: Establish proof of mailing and delivery for court documents and contracts, support chain-of-custody requirements, and reduce liability in sensitive communications.

• And More: Any organization that depends on accurate, accountable, and timely mail delivery can rely on Intelligent Mail Barcoding to help ensure that your mail arrives, and that you know when it does.

How IMbs Support Regulatory Compliance

Intelligent mail barcodes help organizations across industries maintain chain-of-custody records, reduce liability from missed or disputed deliveries, support audits with time-stamped USPS scan data, and respond quickly to undelivered or returned mail. IMbs are also of particular assistance in meeting compliance requirements in the healthcare, finance, and government sectors, such as:

• HIPAA: IMbs help healthcare providers identify undelivered mail, monitor delivery timelines, and demonstrate compliance with HIPAA mailing standards.

• FINRA/SEC: The digital paper trail created by IMbs proves when a mailpiece was sent, entered USPS custody, and reached its destination, supporting compliance with oversight from agencies like FINRA and SEC.

• Government Mailing Standards: IMbs generate full delivery audit trails and reduce the risk of lost or delayed mail, helping public agencies handle sensitive, time-bound mailings such as voter notifications or tax forms.

How Intelligent Mail Barcodes Pair With Variable Data Printing (VDP):

VDP ensures each document is personalized. Intelligent Mail Barcodes give each personalized piece its own digital footprint. When paired together, you gain the ability to track, verify, and optimize all of your personalized mail at the individual level.

• VDP alters text, layout, graphics, or other content based on the individual recipient.

• IMbs are generated on the fly as part of the VDP process, with IMb data fields such as Mailer ID, Service Type, Sequence Number, and Routing Code being pulled from the same dataset that drives VDP personalization.

• While traditional batch mailing offers delivery visibility only by group or tray, IMbs tied to VDP allow true piece-level intelligence, enabling targeted re-mailing, customer service responses, and compliance verification.

• Tying IMbs to VDP simplifies workflows and reduces manual prep and sorting by enabling a multitude of variations and tracking to be handled on just one print run.

Why Intelligent Mail Barcodes Matter:

When customer expectations are high, and regulatory compliance is a paramount concern, IMbs give mailing programs the data they need to effectively reach clients and optimize their workflows. Here’s a summary of how:

• While traditional mail offers little transparency once it leaves your hands, IMbs enable end-to-end tracking, giving you real-time updates, predictive delivery windows, and proof of mailing at the individual document level.

• The chain of custody and time-stamped delivery evidence provided by Intelligent Mail Barcodes help your business comply with HIPAA and other regulations.

• Intelligent Mail Barcodes are efficient on an operational level: since IMbs are embedded during the VDP process, no extra handling is required.

• IMbs reduce return mail, delays, and manual intervention.

• Every IMb scan returns data that can be turned into actionable insights, allowing you to optimize delivery timing, respond to customer inquiries, or feed metrics into your CRM.

If your business depends on mail reaching the right person at the right time, and you being able to prove that it did, then Intelligent Mail Barcodes aren’t optional. They’re essential.
