Known Canpar Limitations

Canpar availability and shipping options depend on the Canpar shipper account and ShipHero account setup.

Limitation Detail

Dangerous goods Canpar may reject dangerous goods based on the service, route, or shipper account. Confirm eligibility with Canpar before shipping.

PO boxes Canpar shipments to PO boxes are not supported.
Return labels ShipHero cannot create Canpar return labels.
U.S. rates Canpar rates for U.S. destinations depend on the shipping methods configured for your account.

Canpar Rate and Label Errors

Canpar rate and label errors often point to a phone number, postal code, credential, or account service setting.

Error or symptom Likely cause What to do
“Delivery address: Invalid address phone format” The recipient or shipper phone number is not in a format Canpar accepts. Canpar allows up to 16 characters. Correct the phone number on the order or shipper address, then request rates or create the label again.
“Invalid delivery postal code or postal code and province combination” The destination postal code or province does not match Canpar’s records. Check the destination postal code and province on the order, then try again.
“Destination postal code … not found” Canpar cannot find the destination postal code. Verify the postal code with the recipient and Canpar, then update the order.
“NSR not allowed” The Canpar account requires a signature for the lane or service. Add the signature option if available. Contact Canpar or ShipHero Support if the error continues.
“Dangerous goods not allowed for this service” The service or shipper account does not allow dangerous goods for this shipment. Confirm whether Canpar allows dangerous goods for your account and route. Use Ground only when Canpar confirms that your shipment is eligible.
“Unauthorized shipper” The shipper number is wrong, or the Canpar account is not enabled for the requested service or option. Check the shipper number. Contact Canpar to confirm the account is enabled for the service, then contact ShipHero Support if the error remains.
“Object cannot be empty: password / user_id” The Canpar connection is missing a username or password. Reconnect Canpar with the correct username and password. Contact ShipHero Support if the credentials are correct and the error continues.
“This service not allowed” The selected service is not enabled for the Canpar shipper account. Choose a service enabled on your Canpar account or ask Canpar to enable it.
No Canpar rates for a U.S. address The Canpar shipping methods configured for your ShipHero account may not include a U.S. service for rating. Contact ShipHero Support to check the Canpar services configured for your account.
A label uses Ground after Select or Overnight was selected Your account may not be set up to send the selected Canpar service on labels. Contact ShipHero Support to check your Canpar service setup before creating more labels.
Saturday delivery is missing Saturday delivery is limited to eligible services and shipments sent Friday with one-day transit. Your account may also need setup. Check the ship date and service. Contact Canpar to confirm eligibility and ShipHero Support to verify your account setup.

Canpar Manifest and Void Issues

Canpar end-of-day manifests close out shipments for the selected shipper and date. A manifest request that is already processing may remain pending until Canpar finishes.

Error or symptom Likely cause What to do
“Shipment has been already manifested” when voiding The end-of-day manifest was submitted before the void request. Canpar no longer allows the void. Contact ShipHero Support or your Canpar account representative for next steps.
Manifest remains pending Canpar reports that an end-of-day process is already running. Wait for the current process to finish before retrying. Contact ShipHero Support if the manifest remains pending.
No manifest document is returned Canpar has no shipments to manifest for that shipper and date. Check that the correct shipper and date have shipments. If you expected a manifest, contact ShipHero Support.

Canpar Tracking Issues

ShipHero retrieves Canpar tracking updates from the carrier. A status of “Unknown” means ShipHero does not recognize the Canpar event code.

If tracking remains unchanged or shows “Unknown,” confirm the tracking number on the shipment and contact ShipHero Support with the tracking number and the status shown.
