Important — Barcode Registration & Legal Use
EAN-13, EAN-8 and UPC-A barcodes used on retail products and marketplace listings must be registered with GS1 India (Indian prefixes start with 890). Using randomly generated numbers without GS1 registration may cause listing conflicts on Amazon, Flipkart and other marketplaces.

Code 128 and Code 39 require no registration and are suitable for internal use — warehouse labels, shipping slips and SKU tracking.

This tool generates barcodes for informational and operational purposes only. Always verify with your CA or marketplace support before printing on packaging intended for formal retail.
Frequently Asked Questions

Barcode types, GS1 standards, print sizes and best practices for Indian e-commerce sellers.

EAN-13 is the standard for Indian retail. Required by Amazon India, Flipkart, Meesho and most POS systems. Register with GS1 India for a company prefix (starts with 890). For internal SKU tracking, Code 128 requires no registration.

The first 3 digits of an EAN-13 indicate the GS1 Member Organisation. 890 = India (GS1 India). Other common prefixes: 000–039 = USA/Canada, 400–440 = Germany, 880 = South Korea, 690–699 = China. The prefix identifies who issued the company prefix, not where the product was made.

ITF-14 labels shipping cartons containing multiple retail units — a 14-digit code with a leading indicator digit (0–8), followed by the EAN digits of the contained product and a check digit. Required by large retailers (D-Mart, Reliance, Amazon FBA) for distribution centre identification.

GS1 standard 100% magnification = 37.29 mm × 26.26 mm. Minimum allowed is 80% (29.83 mm × 21.01 mm). For packaging, print at 100% or larger. Always test with at least two scanner apps before finalising your print run.

SVG for print, always. Infinitely scalable with no pixelation — what professional printers and design software (Illustrator, CorelDRAW, Canva) expect. PNG 3× works for label printers and digital use but pixelates if scaled further.
