What Is USPS Full-Service Certification?

USPS Full-Service is the highest tier of mail preparation, combining three requirements that unlock the deepest discounts and most advanced tracking available from USPS.

1

Intelligent Mail Barcode (IMb)

A unique 65-bar barcode on every mailpiece that encodes routing, mailer ID, and a unique serial number for piece-level tracking from induction to delivery.

2

Electronic Documentation (eDoc)

All postage statements, mailing manifests, and container data are submitted electronically via PostalOne! using mail.dat files — no paper forms, no manual calculations.

3

Move Update Compliance

Addresses must be updated within 95 days of mailing using NCOA, ACS, or other USPS-approved methods. Full-Service automates compliance tracking via eDoc.

Who handles this for you: Mail Movers manages all three Full-Service requirements on your behalf. You provide print-ready artwork and a mailing list — we handle IMb assignment, mail.dat generation, PostalOne! submission, and USPS entry. You never need to interact with USPS systems directly.

Inside the Intelligent Mail Barcode (IMb)

The IMb is a 65-bar barcode that encodes five distinct data fields. Understanding what's in the barcode helps explain why Full-Service tracking is so precise.

Example IMb (65 bars)
01 · 234 · 123456789 · 000001 · 218041234
IMb FieldPurpose
Barcode ID (2 digits)Identifies the barcode type (01 = Full-Service)
Service Type ID (3 digits)Encodes the mail class and service level
Mailer ID (6 or 9 digits)Uniquely identifies the mail service provider (Mail Movers)
Serial Number (6 or 9 digits)Unique sequence number for each individual piece
Routing Code (up to 11 digits)ZIP+4 + delivery point for automated sorting

The IMb is scanned at every USPS processing facility and delivery point, creating a complete movement history for each piece. This data is available through USPS Business Customer Gateway and can be integrated with your CRM or campaign analytics.

PostalOne! and Electronic Documentation (eDoc)

PostalOne! is the USPS system that receives electronic mailing data before your mail arrives at the post office. Full-Service certification requires eDoc submission for all mailings over 500 pieces.

mail.dat File

A standardized electronic file containing all mailing job data — piece counts, postage calculations, container and tray information, and IMb assignments. Mail Movers generates and submits mail.dat files for every Full-Service mailing.

Electronic Postage Statement

Replaces paper PS Forms 3600, 3602, and 3541. Postage is calculated automatically from the mail.dat file, eliminating manual errors and reducing BMEU processing time from hours to minutes.

Container and Tray Manifests

Every tray and sack of mail is electronically manifested with a barcode that links back to the mail.dat file. USPS can verify the contents of any container without opening it.

Electronic ACS (Address Change Service)

When a piece is undeliverable or the recipient has moved, USPS returns an electronic notification with the new address. This data is used to update your mailing list — included at no extra charge with Full-Service.

Full-Service vs. Basic Mail Preparation

Basic mail preparation is the minimum required for presort rates. Full-Service adds IMb, eDoc, and tracking — and unlocks additional discounts that more than offset any additional preparation cost.

The Intelligent Mail Barcode (IMb) is a 65-bar barcode printed on every Full-Service mailpiece. It encodes five data fields: Barcode ID, Service Type ID, Mailer ID, Serial Number, and Routing Code (ZIP+4 + delivery point). As your mail moves through the USPS system, the IMb is scanned at processing facilities and delivery points, providing piece-level tracking from induction to delivery. This data is available through USPS Business Customer Gateway and can be integrated with your CRM or campaign analytics tools.

PostalOne! is the USPS electronic documentation system that Full-Service providers use to submit postage statements, mailing manifests, and mail.dat files electronically. It replaces paper PS Forms and manual calculations, reducing errors and processing time at the USPS Business Mail Entry Unit (BMEU). Full-Service certification requires PostalOne! submission for all mailings over 500 pieces. Mail Movers handles all PostalOne! submissions on your behalf — you never need to interact with the system directly.

Informed Delivery is a free USPS service that sends residential recipients a daily email digest showing grayscale scans of their incoming mail. As a Full-Service mailer, you can enhance your Informed Delivery campaign by adding a full-color digital ride-along image and a clickable URL to the notification — extending your direct mail piece into the digital channel at no additional postage cost.

Basic mail preparation uses paper postage statements, optional barcodes, and manual address correction (ACS) notices that cost $0.07–$0.09 each. Full-Service requires IMb on every piece, electronic documentation via PostalOne!, and provides piece-level tracking, electronic UAA data, automated move update compliance, and the additional $0.003/piece Full-Service IMb discount. For any mailing over 500 pieces, Full-Service almost always produces lower total cost and better campaign data.

A mail.dat file is a standardized electronic file format used to transmit mailing job data to PostalOne!.

Mail Movers generates and submits mail.dat files for every Full-Service mailing, ensuring accurate postage calculations and seamless USPS acceptance. You never need to create or manage mail.dat files yourself.

You need a USPS mailing permit (Permit Imprint account) to mail at presort automation rates. Mail Movers can help you establish a permit at the Salisbury, MD Post Office, or you can mail under our permit for a nominal fee. You do not need a postage meter — permit imprint indicia are printed directly on your mailpieces as part of our production process. Call 410-749-1885 to discuss the best permit arrangement for your mailing volume.

Full-Service provides electronic Address Change Service (ACS) data at no additional charge. When a piece is undeliverable or the recipient has moved, USPS sends an electronic notification with the old address, new address (if available), and reason code. This data is returned to Mail Movers and can be used to update your mailing list, reducing waste on future mailings. Basic mail preparation charges $0.07–$0.09 per ACS notice; Full-Service includes this data electronically at no extra cost.

Yes — Full-Service is available for Nonprofit Marketing Mail and provides the same IMb tracking, eDoc, and Informed Delivery benefits as commercial mailings.
