Best practices for preventing import failures
| S.No. | Error | Description | User action required |
|---|---|---|---|
| 1. | ErrorCsvInvalid | CSV file format is incorrect, resulting in unparsability | Import data using the correct template we provide |
| 2. | ErrorCsvTooLarge | CSV file size is more than 5MB | Split files to reduce individual file size |
| 3. | ErrorCsvEmpty | CSV file is empty | Fill in the CSV file with tracking data using our basic or full CSV template |
| 4. | ErrorCsvTooManyRows | The number of shipments imported at a time exceeds the maximum limit which is 60,000 for whitelist Enterprise users and 10,000 for other users | Split files to reduce shipment volume per CSV file |
| 5. | ErrorCsvNoRecord | CSV file with no data | Fill in the CSV file with tracking data using our basic or full CSV template |
| 6. | ErrorCsvColumnsInconsistent | CSV file wrong format. The data column count does not match the table header count | Please add the missing headers or reduce the data columns to align the data |
| 7. | ErrorCsvDuplicate | Repeat import of the same CSV file | Please change the file content |
| 8. | ErrorUrlAccessDenied | No permission to access the user's CSV file or FTP server | Please check whether the FTP rule configuration within the AfterShip admin is correct |
| 9. | ErrorFetchCSVDataFailed | Unable to connect to the user's FTP server | Please check whether your FTP service is operating normally and hosted on the public network |
| 10. | ErrResourceNotFound | File does not exist | Please check whether the file address is correct |
Troubleshooting
Always use the latest AfterShip CSV template for your data format to avoid structural errors.
Validate your CSV file in a spreadsheet tool (like Excel or Google Sheets) before importing.
If you're importing via FTP, confirm your server is online and credentials are up to date.
Large import files? Break them into smaller parts and ensure each is within file size and row limits.
For ongoing issues, consider testing the file with a few rows before bulk import.
FAQs
1. What is the maximum number of shipments I can import via CSV?
Enterprise users with whitelist access can import up to 60,000 rows, however all other users can import up to 10,000.
2. What if I keep getting ErrorCsvDuplicate even though I’ve edited the file?
Make sure the data itself (not just the file name) is different. AfterShip checks for content duplication.
3. Can I use my own CSV format instead of the AfterShip template?
No, using the AfterShip-provided basic or full CSV template is mandatory for proper import parsing.
Key takeaways
CSV imports may fail due to issues with formatting, size, permissions, or server connectivity.
AfterShip provides specific error codes to help diagnose and resolve problems quickly.
Using the correct template and adhering to size/row limits ensures a smooth import process.
FTP-based imports require careful configuration to avoid access and connectivity errors.
