Updating or Correcting an Accepted ACI eManifest (ACI eManifest)
Last updated 30 July 2026

| This article is part of the BorderConnect ACI eManifest Guide |
This guide offers instructions on making updates or corrections to an ACI eManifest using BorderConnect ACI eManifest software. It assumes that the manifest has already been submitted and is on file with CBSA using BorderConnect ACI.
The changes in this guide can only be made prior to the driver's arrival at the border.
The procedure for changing a manifest depends on what part of the manifest needs to be changed. Most changes can be processed using eManifest Sync, but a few types of changes require additional steps.
In most cases, eManifest Sync is the default and recommended method for making changes or corrections to an accepted ACI eManifest. For all types of changes, first open the manifest from the ACI eManifest Search Page by clicking View.

Overview
Most accepted ACI eManifest corrections are made by editing the information in BorderConnect and then clicking Sync with CBSA. Sync sends the required update, cancellation, resubmission, or shipment-linking message when supported by the current manifest status and change type.
Some changes, such as adding a shipment, removing a shipment, changing the trip number, or changing a cargo control number, require specific steps so CBSA receives the correct trip and shipment updates. These changes should be made before the driver arrives at the border.
Syncing With CBSA
Most types of changes to an ACI eManifest can be completed using Sync with CBSA. For the changes below, make all required edits first, then sync once with CBSA.
- Make the change to the manifest in BorderConnect. If more than one item needs to be changed, complete all changes before moving to the next step.
- Changes to the port of entry or ETA (including date) can be made using the Edit button near the top left of the page. Once the changes are made, clicking Save updates the manifest in BorderConnect. The system will offer to update all attached shipments to match the port or ETA change made for the trip. Select Yes for this option.

- Changes to the truck or trailer can be made by clicking the Remove link for the current truck or trailer. Then use Quick Assign Truck or Quick Assign Trailer to add the new one to the manifest. The driver can also be updated this way, but the driver is not transmitted to CBSA and is only listed on the manifest for reference.
- Changes to seal numbers can be made by clicking the View link on the trailer or truck, depending on where the seals are located. From there, add, remove, or edit the seals. Once finished, use the Back to ACI eManifest button.
- A cargo exemption can be added to the truck or trailer by mousing over the Set Cargo Exemption button and selecting the appropriate exemption. A cargo exemption can be removed by clicking the Remove Cargo Exemption Code link for the truck or trailer.
- Changes to shipper, consignee, or commodity information can be made by clicking the View link for the shipment. From there, use the Remove from Shipment link on the shipper or consignee that needs to be changed, then assign or quick-assign the new one. The Edit link can be used instead to fix a mistake. Commodity information can be updated with the Edit link for the commodity, or by clicking Create Commodity to add another commodity to the shipment.
- Transmit the changes to CBSA. After the changes have been made in BorderConnect, CBSA will require the eManifest to be synced to see them.
- Use Sync with CBSA at the top of the ACI eManifest Details page to update the manifest with CBSA.

- Use Send Change Shipment Request (available only from Send to CBSA inside the shipment) if the changes only involve information in that shipment, such as shipper, consignee, or commodity information.
- Check back to verify that the change request is accepted by CBSA. Syncing the ACI eManifest updates the trip and/or shipment status to Transmitted to CBSA. When the ACI eManifest is accepted, the status reverts to On File with CBSA or On File with Transaction Numbers, and an accepted response appears under the ACI eManifest History.
Changing Trip Number or Cargo Control Number
Changes to the trip number or cargo control number also require the user to Sync with CBSA after the changes have been made. The manifest does not need to be re-entered in BorderConnect.
- Changing the Trip Number. This can be done on either an already cancelled manifest or a manifest that is already on file with CBSA. Click Edit on the top left of the ACI eManifest Details page, change the trip number, then click Save to return to the ACI eManifest Details page. From there, click Sync with CBSA to change the trip number with CBSA. The sync may take a few minutes. The eManifest Tracking Feature can be used to alert the user when the response comes in.
- Changing the Cargo Control Number(s). This can be done on either an already cancelled manifest or a manifest that is already on file with CBSA. Scroll down and edit the shipment, then change the cargo control number. Once it has been changed, click Save to return to the ACI Shipment Details page. From there, click Back or Back to eManifest, then click Sync with CBSA from the top of the ACI eManifest Details page. The sync may take a few minutes. The eManifest Tracking Feature can be used to alert the user when the response comes in.
Adding a Shipment to the Manifest
Adding a shipment to the manifest also involves syncing with CBSA.
- Add the shipment to the manifest in BorderConnect. Use the Create New Shipment button on the manifest, then enter all required data for an ACI shipment, including shipper, consignee, and commodity.
- Send the shipment to CBSA. This should be done from the ACI eManifest Details page by clicking Sync with CBSA.
- Wait for the eManifest Sync to complete. Once the sync is complete, the manifest will revert back to accepted with either three blue bars or four green bars. Because this can take 10 minutes or more, the user may want to go back to the ACI eManifest and use the eManifest Tracking Feature to alert them when the response comes in. An accepted response will appear in the ACI eManifest History.
- Check back to verify that the change request was accepted. The manifest status updates to On File with CBSA or On File with Transaction Numbers, and an accepted response appears under the ACI eManifest History.
Removing a Shipment from the Manifest
Removing a shipment from a manifest involves three steps. First, detach the shipment from the manifest. Next, sync with CBSA to de-link the shipment from the manifest in CBSA's system. Finally, cancel the shipment itself out of CBSA's system.

- Detach the shipment from the manifest in BorderConnect. To do so, use the Detach link for the shipment.
- Click Sync with CBSA from the original manifest. This de-links the shipment from the manifest in CBSA's system by updating the list of attached shipments.
- Wait for the sync to complete. The manifest status updates to On File with CBSA or On File with Transaction Numbers, and an accepted response appears under the ACI eManifest History.
- Cancel the shipment with CBSA. Now that the shipment is no longer linked to the manifest in CBSA's system, it is important to go back and cancel it. Because the shipment can no longer be accessed from the manifest, search for it on the ACI Shipment Search Page and click View to access the shipment. From there, under Send to CBSA, choose Send Cancel/Delete Shipment Request.
- Check back to verify that the cancellation was accepted. When the cancellation is accepted by CBSA, the status changes to Cancelled and an accepted response appears in the ACI Shipment History.
