Frequently Asked Questions
What barcode format should I use for retail products in India?
Use **EAN-13** for most retail products in India and internationally. It requires a GS1 company prefix. For internal use and testing, Code 128 is flexible and supports any alphanumeric data.
What is the difference between EAN-13 and UPC-A?
EAN-13 is 13 digits (used internationally). UPC-A is 12 digits (used in North America). Both are standard retail barcodes readable by all POS systems.
Can I create barcodes for Amazon FBA or inventory management?
Yes — Code 128, FNSKU, and EAN barcodes are all supported. Check your platform's specific barcode requirements before generating.
Are there any restrictions on what data I can encode?
Code 128 supports all 128 ASCII characters. EAN-13 and UPC-A are numeric only. Code 39 supports uppercase letters and some special characters.
Is the barcode generator free to use?
Yes — completely free with no login, no subscription, and no watermarks on downloaded images.
What is the difference between a barcode and a QR code?
Traditional barcodes (1D) encode data in horizontal lines and are scanned by laser. QR codes (2D) store more data in a matrix pattern and are read by camera-based scanners and smartphones.
Can I print the generated barcode on product labels?
Yes — download as SVG for scalable, high-quality print output. SVG barcodes can be scaled to any size without pixelation.
