What barcode formats are supported?

We support Code128 (alphanumeric, most versatile), EAN-13 (European retail products), UPC-A (North American retail), Code39 (industrial applications), and ITF/Interleaved 2 of 5 (shipping and packaging).

Which barcode format should I use?

For retail products, use EAN-13 (Europe/international) or UPC-A (North America). For general-purpose alphanumeric data, Code128 is most versatile. For industrial applications with limited characters, Code39 works well. For shipping labels, ITF is commonly used.

What are the character limitations for each format?

EAN-13 requires exactly 12-13 digits. UPC-A requires exactly 11-12 digits. Code128 supports all ASCII characters. Code39 supports uppercase letters, digits, and some symbols. ITF requires an even number of digits.

Can I download the barcode for printing?

Yes, you can download your barcode as a high-resolution PNG image suitable for printing on product labels, packaging, inventory tags, and other materials.

Why is my barcode not scanning?

Common issues include: insufficient contrast between bars and background, barcode too small for the scanner, damaged or distorted print, or incorrect format for your scanner. Ensure adequate quiet zones (white space) around the barcode.

What is a Barcode Generator?

A barcode generator creates machine-readable representations of data using parallel lines (1D barcodes). Unlike QR codes that store information in two dimensions, traditional barcodes encode data horizontally using varying line widths and spacings. Our free online barcode generator supports multiple formats including Code 128 for logistics and shipping, EAN-13 for retail products worldwide, UPC-A for products sold in North America, Code 39 for automotive and defense industries, ITF-14 for packaging, and Pharmacode for pharmaceutical packaging. All barcodes are generated instantly in your browser with complete privacy.
