Label generation errors can occur across any shipping carrier (e.g., FedEx, UPS, DHL, USPS), and are often caused by service availability, address formatting, or package limits.
Common Causes
The selected carrier service is limited or not available for the origin/destination.
The address is unrecognized (new zipcodes, remote locations, etc) or improperly formatted.
The package exceeds the carrier's size or weight limits.
Typical Error Messages
"Shipping label generation failed""The service 'XX' is not valid for this shipment""Unsupported origin or destination""Invalid address"
How to Troubleshoot
1. Check the Address:
Use Google Maps to find the nearest drop-off service point or delivery point near the customer’s address.
Try using that address to regenerate the label — this helps determine if the issue is address-related.
2. Confirm Carrier Service Support:
Reach out to your carrier or 3PL to verify which services are valid for that country or route. Make sure the weight and dimensions fall within the service’s allowable range.
Update support@yayloh.com to update your shipping configuration to use a supported service type.
Still Not Working?
Try generating the label directly via the carrier’s own system to rule out integration issues.
