A barcode identifies a product. It can't prove it's genuine.
Barcodes are public and printed identically on every unit — counterfeiters copy them freely. FirstScanIt adds a cryptographically signed, serialised QR layer that proves authenticity and catches clones the moment they're scanned.

Pick a barcode type, enter your data, and the barcode renders instantly. For retail barcodes (EAN-13, UPC-A, EAN-8, ITF-14) you only enter the data digits — the final check digit is computed automatically using the GS1 modulo-10 algorithm, so the result is always valid. Download a PNG for documents or a scalable SVG for print artwork.
Which Barcode Type Do I Need?
- EAN-13 — the worldwide retail standard. India's GS1 prefix is 890.
- UPC-A — 12-digit retail barcode used mainly in the US and Canada.
- EAN-8 — compact 8-digit code for small packages.
- ITF-14 — printed on shipping cartons and cases for logistics.
- Code 128 — high-density alphanumeric code for internal labels, asset tags, and shipping.
- Code 39 — older alphanumeric code still common in automotive and defence supply chains.
Need an Official Retail Barcode?
To sell through retailers you need a GTIN issued by GS1 (in India, GS1 India). This tool draws a valid barcode from any number, but only a GS1-allocated GTIN is registered to your company. Check any existing number's check digit with the GTIN check digit calculator.

Questions and answers
Can I use these barcodes on retail products?
Yes, if the number itself is yours. Retail GTINs must be issued to your company by GS1.
Which format is best for print?
SVG, because it stays sharp at any size.
Does a barcode stop counterfeiting?
No. Anyone can print a barcode. It identifies a product; it does not prove who made the pack.
