Updating or Correcting an Accepted ACI eManifest (Legacy Method) (ACI eManifest)

Last updated 30 July 2026

On this page
This article is part of the BorderConnect ACI eManifest Guide
In most cases, the default and recommended method for making changes or corrections to an accepted ACI eManifest is to use eManifest Sync. eManifest Sync is enabled by default and is designed to automatically handle supported updates with CBSA after changes are made in BorderConnect. The legacy send options in this guide should only be used if Sync is disabled or when specifically instructed by BorderConnect support. For the standard recommended workflow, see Making Changes or Corrections to an Accepted ACI eManifest Using eManifest Sync.

This guide explains how to update or correct an ACI eManifest that has already been submitted and is on file with Canada Border Services Agency (CBSA). While eManifest Sync can be turned off in the Company Settings page, or disabled on a specific manifest by clicking the three dots at the top right of the manifest details page, this is only recommended in rare cases. The legacy send functions described in this guide should only be used if Sync is disabled or when specifically instructed by BorderConnect support.

Overview

This guide assumes the ACI eManifest has already been submitted and is on file with CBSA. These changes can only be made prior to the driver's arrival at the border.

The correct procedure depends on which data element requires updating. With eManifest Sync enabled, many changes made in BorderConnect are automatically synced with CBSA. If Sync is disabled, or if the user is using the legacy send options, the user may need to manually send a change request, cancel, or resubmit the manifest after making changes.

Initial Step: For all types of changes, first open the manifest by using the ACI eManifest Search Page and clicking View.

Legacy send options on the ACI eManifest Details page

eManifest Sync

eManifest Sync is the recommended method for sending and updating ACI eManifests in BorderConnect. When Sync is enabled, BorderConnect is designed to keep the ACI eManifest in sync with CBSA after supported changes are made.

Users should normally leave Sync enabled unless there is a specific reason to disable it. If Sync has been disabled for the company or for a specific manifest, the user may need to use the legacy send options described below.

For the default workflow, see Making Changes or Corrections to an Accepted ACI eManifest Using eManifest Sync.

Change Requests

Most changes to a submitted ACI eManifest can be processed using a Change Request. This includes many changes to trip, equipment, seal, cargo exemption, shipper, consignee, and commodity information.

The main exceptions are:

  • changing the trip number;
  • changing a cargo control number;
  • adding a shipment; or
  • removing a shipment.

Those changes require the special procedures described in the sections below.

1 Apply Changes in BorderConnect

If more than one change is needed, complete all changes in BorderConnect before transmitting the change request to CBSA.

Information to change How to change it
Port of Entry or ETA Click Edit near the top left of the manifest details page. When saving, select Yes when the system offers to update all attached shipments to match.
Truck or Trailer Click Remove on the current truck or trailer, then use Quick Assign to add the new one.
Drivers Drivers can be updated on the manifest for company reference, but driver information is not transmitted to CBSA.
Seal Numbers Click View on the trailer or truck, depending on where the seals are located. Edit the seals, then click Back to ACI eManifest.
Cargo Exemptions Mouse over Set Cargo Exemption to add a cargo exemption. Click Remove Cargo Exemption Code to remove one.
Shipper, Consignee, or Commodity Click View for the shipment. Use Remove from Shipment and Assign or Quick Assign to update parties, or use Edit to correct commodity information.

2 Transmit to CBSA

Under Send to CBSA, select the appropriate message type based on the changes that were made.

Option When to use
Change Trip and Shipments Use for changes to both trip data and shipment data, such as port or ETA changes that should also update attached shipments, or when multiple varied changes were made.
Change Trip Only Use for changes to trip-level information only, such as truck, trailer, seals, or cargo exemptions.
Send Change Shipment Request Use inside the shipment when only shipment information changed, such as shipper, consignee, or commodity details.

3 Verify Acceptance

After the change request is sent, the manifest or shipment status will update while the request is pending. When CBSA accepts the change request, the manifest or shipment should return to an accepted or on-file status.

Review the ACI eManifest History or shipment history to confirm the accepted response. Do not assume the change has been accepted until the accepted response is visible.

Changing Trip Number

The trip number is a structural identifier and cannot be changed using a regular change request. To change the trip number, cancel the trip and then resubmit it with the corrected number.

  1. Under Send to CBSA, select Cancel Trip Only.
  2. Wait for CBSA acceptance. This can take 10 minutes or longer.
  3. After the cancel is accepted, click Edit on the manifest and update the trip number.
  4. Click Save.
  5. Under Send to CBSA, select Send Trip Only or Send Trip and Shipments, depending on what was cancelled and what needs to be re-filed.
  6. Confirm that CBSA accepts the corrected trip.

Changing Cargo Control Number

The cargo control number is a structural shipment identifier and cannot be changed using a regular change request. To change a cargo control number, cancel the trip and shipment data as needed, update the shipment, and resubmit.

  1. Under Send to CBSA, select Cancel Trip and Shipments.
  2. Wait for CBSA acceptance. This can take 10 minutes or longer.
  3. Click View for the shipment.
  4. Click Edit inside the shipment.
  5. Update the cargo control number and click Save.
  6. Return to the ACI eManifest details page.
  7. Under Send to CBSA, select Send Trip and Shipments.
  8. Confirm that CBSA accepts the corrected trip and shipment.

Adding a Shipment

Adding a shipment requires two distinct requests to ensure CBSA links the new shipment data correctly to the existing trip.

  1. Click Create New Shipment on the manifest and enter all required shipment data.
  2. Inside the shipment, under Shipment Only Send to CBSA, select Send New Unassociated Shipment Request.
  3. Wait until the shipment status is On File. This may take approximately 10 minutes.
  4. Return to the main manifest page.
  5. Under Send to CBSA, select Change Trip Only to link the shipment to the trip.
  6. Confirm that CBSA accepts the trip change and that the shipment is linked to the manifest.

Removing a Shipment

Removing a shipment also requires separate steps so CBSA knows the shipment is no longer attached to the trip and, if needed, that the shipment itself should be cancelled.

  1. Click Detach on the shipment within the manifest details.
  2. Under Send to CBSA, select Change Trip Only to update the list of attached shipments with CBSA.
  3. Go to the ACI Shipment Search Page.
  4. Search for the cargo control number and click View.
  5. Under Send to CBSA, select Send Cancel/Delete Shipment Request.
  6. Confirm that CBSA accepts both the trip change and the shipment cancel/delete request.

Best Practices

  • Keep eManifest Sync enabled unless BorderConnect support instructs otherwise.
  • Use Making Changes or Corrections to an Accepted ACI eManifest Using eManifest Sync as the default recommended workflow for most accepted ACI eManifest corrections.
  • Make all required changes in BorderConnect before sending a change request.
  • Use the correct change option for the type of data being updated.
  • Wait for CBSA acceptance before making the next related change.
  • Do not change structural identifiers, such as trip number or cargo control number, before cancelling the original record with CBSA.
  • Use ACI eManifest History and shipment history to confirm accepted responses.
  • Make corrections before the driver arrives at the border whenever possible.
  • If the driver has already arrived or the manifest status is unclear, contact BorderConnect support before making major changes.
