Frequently asked questions

Does this tool assign official product numbers?

No. It creates an image from your number. Confirm official numbering and marketplace requirements before using retail product codes.

What if a check digit is invalid?

Check the original number. You may omit the final digit to calculate it, or enter a full number for validation.

Can I create multiple labels?

Use the bulk tool and a CSV file. Keep number columns as text to preserve leading zeros.
