Printing Best Practices
To ensure your barcodes scan correctly every time, follow these tips:
- High Contrast: Use black bars on a white background. Avoid light colors or transparent backgrounds.
- Scale Carefully: Do not stretch or compress the barcode, as this can change the width of the bars and make them unreadable.
- Quiet Zone: Maintain a clear space around the barcode (the 'Quiet Zone') to help scanners identify the start and end of the code.

UPC-A is primarily used in the United States and Canada, while EAN-13 is the standard for the rest of the world. EAN-13 is essentially a 13-digit version of the 12-digit UPC.
Can I generate a QR code with this tool?
Yes! Select 'QR Code' from the format list to generate a scannable 2D code for URLs, text, or contact information.
What format should I download for printing?
We recommend high-resolution PNG or SVG formats to ensure the bars remain sharp and scannable when printed on labels.

FAQs
What is Code 128?
Code 128 is a very high-density alphanumeric barcode. It can encode all 128 characters of ASCII and, by use of an extension character, the Latin-1 characters. It is widely used in shipping and packaging industries.
What is the difference between UPC and EAN?
UPC (Universal Product Code) is primarily used in the USA and Canada, typically consisting of 12 digits. EAN (European Article Number) is used globally and typically consists of 13 digits. Both are used for retail point-of-sale scanning.
Can I use these barcodes for commercial products?
To put a scannable barcode on a commercial retail product, you typically need to purchase a unique prefix from GS1. While this tool generates technically valid barcodes, you must own the number sequence to use it legally in retail stores.
