USPS allows shipments to be scanned in a scan form at once if the shipment is large. This sheet will contain bar codes of each individual mail.

Sometimes this status “Shipment Received, Package Acceptance Pending” may be due to the failure of the post office receiving the mails and doing their due diligence.

The shipment can be taken to the local post office or it can be picked up by the carrier at the senders premise. Now once the shipment is received at the post office the tracking changes to: “Shipment Received, Package Acceptance Pending” on each of the individual tracking pages.

If not for the Scan Form, the postal worker would have to scan each of the items individually this may cause frustration to the clerk. Here the clerk is required to scan each mail individually and therefore change status from ”Shipment received, package acceptance pending” to ”Received” status but due to the work being too much this may not happen.

The Mails or the shipment will continue with the the transit journey of delivery even without another scanning and therefore the status remaining the same.

It can also be mean that the sender has provided a tracking number but has failed to deliver the items to post office for further processing and forwarding.
