❓ Frequently Asked Questions
Everything you need to know about barcode generation
Which barcode formats are supported?
We support all mainstream barcode formats: CODE128 series (for any ASCII characters), EAN-13/EAN-8 (product barcodes), UPC-A (North American product codes), CODE39 (industrial applications), ITF-14/ITF (logistics packaging), MSI series (inventory management), and Pharmacode (pharmaceutical industry).
How do I choose the right barcode format?
Format selection depends on usage: use EAN-13 or UPC-A for product sales; CODE128 for alphanumeric content; CODE39 for industrial environments; ITF-14 for logistics packaging; Pharmacode for pharmaceutical products. Our tool automatically validates whether input content meets the selected format requirements.
What is a check digit and how is it calculated?
A check digit is the number at the end of a barcode used to verify barcode correctness. For EAN-13, EAN-8, UPC-A, and ITF-14 formats, if you enter one digit less, we automatically calculate and add the check digit; if you enter the complete digits, we verify whether the check digit is correct.
Can the generated barcodes be used commercially?
Yes! Our generated barcodes fully comply with international standards and can be used for commercial purposes. However, note that certain formats (like EAN-13, UPC-A) require applying for official product codes from relevant organizations. Our tool is mainly for testing, internal management, or generating barcodes for existing codes.
What's the difference between PNG and SVG formats?
PNG is a bitmap format, suitable for direct use and printing with smaller file sizes; SVG is a vector format that can be scaled infinitely without quality loss, suitable for scenarios requiring size adjustments. We recommend PNG for printing and SVG for design and large-scale applications.
