How to Create USPS SCAN Forms for Ecommerce
By Anata Inc. ·

The short answer.
Use a USPS Shipment Confirmation Acceptance Notice, or SCAN form, to group eligible labels under one master barcode for a shipment handoff. Create labels with the correct ship date and ship-from ZIP Code, verify the package list, generate and print PS Form 5630 before the applicable deadline, and present the complete group with the form. The USPS acceptance scan applies a Shipment Accepted event to the associated packages. Preserve the form, label manifest, package count, pickup or counter handoff, and tracking evidence. Reconcile any missing package or scan immediately, and never assume the master scan proves delivery or correct postage for every parcel.
Section 01
Build the shipment group from label truth
A SCAN form is a shipment-acceptance tool, not a replacement for correct labels. Start with the packages physically ready for the USPS handoff. Verify each label's tracking number, service, ship date, ship-from ZIP Code, destination, weight, dimensions, postage, and package contents. Remove canceled, refunded, duplicate, damaged, or not-yet-packed labels before generating the form. The digital list must match the containers leaving the facility.
USPS describes PS Form 5630 as a master form that represents multiple packages. In Click-N-Ship, transactions with two or more labels can automatically receive a SCAN form, and users can create, manage, print, and reprint forms from the SCAN Forms area. High-volume or integrated shippers can also use approved manifesting workflows. Confirm the current workflow used by the label system rather than mixing labels from unrelated manifests.
Assign one owner to close the group. That person should count packages, compare the count with the manifest, confirm the ship date and origin, print the readable master barcode, and prevent late label changes. Record excluded packages and why they were excluded. A label created after the form is closed should move through an approved supplemental or individual acceptance path, not be placed in the pile without evidence.
Section 02
Create and print the form on time
Create the SCAN form from labels that share the required manifest conditions. USPS Click-N-Ship guidance says users can manually add labels with the same ship date and ship-from ZIP Code, and the form must be created and printed by the stated deadline on the ship date. Check the current interface because deadlines and field requirements can change. Do not wait until the driver arrives to discover an ineligible label or printer problem.
Review the package list before printing. Confirm label count, tracking numbers, service mix, origin, and ship date. After the form is created, follow the system's restriction on changes. USPS warns Click-N-Ship users that no changes can be made after printing and that labels on a form have refund consequences when they are not shipped with that form. Treat printing as the manifest close, with any correction routed through the documented recovery process.
Test barcode quality. Print at the supported size, avoid scaling that distorts the code, and keep toner, paper, and scanner contrast reliable. Store a controlled copy with the shipping batch record while protecting customer data. If the barcode is damaged or unreadable before handoff, use the approved reprint path. Do not redraw, crop, or manually reconstruct the barcode from a screenshot.
Section 03
Control the physical acceptance handoff
Present the complete package group and the SCAN form together at the scheduled pickup or acceptance location. The master barcode must be scanned by USPS at acceptance. USPS explains that this single scan enters the associated packages into tracking as Shipment Accepted. Observe the handoff when practical and preserve the form or receipt evidence according to the operating record policy.
Understand what the scan proves. It records acceptance for the linked labels, improving visibility into when the shipment entered the mailstream. It does not prove that every package had the correct weight, dimensions, postage, contents, or destination, and it does not prove delivery. Keep label creation, packing verification, acceptance, movement, delivery, claims, and refunds as separate evidence stages.
Handle exceptions at the dock. If the package count differs, a parcel is missing, or the form will not scan, stop and reconcile before the handoff closes. Identify every affected tracking number and route it through individual acceptance or a corrected manifest only when USPS and the shipping system support that action. Never send an unmanifested extra package in the group and assume the master barcode covers it.
Section 04
Reconcile acceptance and investigate gaps
After handoff, compare the manifest with tracking evidence. Confirm that the expected packages received the Shipment Accepted event and record the scan time. Review missing acceptance events, duplicate labels, refunded labels, late-added packages, and packages that remain at label-created status. Use the manifest, physical count, pickup record, carrier event, and warehouse close record together before deciding what happened.
Create an exception queue with tracking number, batch, form identifier, package owner, issue, last evidence, next action, and due time. Contact the appropriate USPS support channel with specific package and form evidence when the operating record does not reconcile. Do not tell a customer that a parcel was accepted or lost based only on an internal label record. Use carrier evidence and keep the statement limited to what the record supports.
Measure form usage, packages per form, missing-acceptance rate, late manifest additions, unreadable forms, excluded labels, and time to reconcile. Segment by facility, workstation, pickup, label source, and operator. Fix deterministic problems first: address errors, wrong ship dates, printer quality, package-count mismatch, or late manifest close. The goal is a clean carrier handoff with traceable evidence, not simply a printed form.
Keep the batch record long enough to support the business's shipping, support, refund, and claims workflow, while limiting access to customer data. Define retention from approved policy rather than convenience. When records expire, remove them through the governed process without erasing the aggregate operating evidence needed to improve future handoffs.
