USPS Full-Service Certified Mail: Preparation and Tracking Review
Mail Movers is USPS Full-Service Certified. We can support IMb barcoding, PostalOne! electronic documentation, Informed Delivery campaign components, and available scan visibility. USPS determines eligibility, requirements, and any postage adjustment for each mailing.
What Is USPS Full-Service Certification?
USPS Full-Service is a mailing-preparation option with requirements that are reviewed against current USPS standards for the individual job.
Intelligent Mail Barcode (IMb)
For qualifying cards, letters, and flats, a 65-bar IMb can encode routing, mailer ID, and serial-number data. IMpb is the distinct barcode for packages; scan visibility varies.
Electronic Documentation (eDoc)
Electronic documentation requirements and submission methods are reviewed for the specific mailing under current USPS standards.
Move Update Compliance
Move-update and address-quality requirements depend on the mailing and current USPS standards. Applicable options are reviewed during project planning.
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 tracking data. IMpb is the distinct barcode for packages; USPS scan availability and timing vary by mailing and operations.
| IMb Field | Purpose |
|---|---|
| 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 |
USPS may record scan events for qualifying mail. The availability, timing, and detail of scan information vary by mailing and operations and do not establish a delivery guarantee.
PostalOne! and Electronic Documentation (eDoc)
PostalOne! is a USPS system used for electronic mailing documentation. The required documentation, timing, and submission method depend on the mailing and current USPS standards.
mail.dat File
A standardized electronic file format that can transmit qualifying mailing-job data. Required data and use depend on the mailing and USPS standards.
Electronic Postage Statement
Electronic postage documentation may be required for qualifying mailings. The applicable forms, data, and preparation are reviewed for the job.
Container and Tray Manifests
Container and tray documentation may be required based on the mailing’s preparation and current USPS standards.
Electronic ACS (Address Change Service)
Address-correction options, available data, timing, and charges depend on the mail class, service selection, and current USPS standards.
Informed Delivery: Extend Your Mail Campaign into the Digital Channel
Informed Delivery is a USPS service that provides eligible residential users with digital previews of incoming mail. Campaign features, participation, and measurement depend on the mailing and current USPS program requirements.
