Frequently asked questions
Is this a real, scannable barcode?+
Yes. It's drawn from the official UPCA specification with proper module widths, quiet zones and an auto-calculated check digit, so standard barcode scanners and apps read it correctly.
Do I need to include the check digit?+
No — enter the 11 data digits and the tool computes and appends the final check digit automatically. If you enter the full number, it's verified for you.
How do I get a valid retail (GS1) number?+
To sell in shops you need a GTIN from GS1 (the body that issues unique company prefixes). This tool renders any number you own into a compliant barcode image — it doesn't assign you a number.
Is my data uploaded?+
No — the barcode is rendered on a canvas in your browser; nothing is sent anywhere.
